I have a certificate with a generated a CSR within go daddy.
I tried generating my own CSR to get a certificate for my domain.
I have followed their tutorial to generate a store with the CSR:
keytool -genkey -alias codesigncert -keypass -keyalg RSA -keysize 2048 -dname "CN=displayname,O=companyname,C=US,ST=state,L=city" -keystore codesignstore -storepass
But the godaddy rejected the generated CSR, so I used the one they generate.
After that I used this command from a tutorial at thomasvitale.com.:
keytool -import -alias <my alias> -file <downloadedcertificate file>.crt -keystore keystore.p12 -storepass password
The generated .p12 keystore wouldn't boot because spring said:
DerInputStream.getLength(): lengthTag=109, too big.
Reading a LOT on that I have found out it was the way the keystore was generated and the version of something. Because of that I had to generate another keystore.
To generate the current problematic keystore I tried following medium.com instructions:
Used this to generate the keystore:
keytool -genkey -alias <alias> -keyalg RSA -keystore <keystore.jks> -keysize 2048
Used this to generate a CSR:
keytool -certreq -alias <alias> -keystore <keystore.jks> -file <domain>.csr
Sent the CSR to generate the ssl certificates, downloading them using the tomcat option. Then imported the certificates:
intermediate certificate: keytool -import -trustcacerts -alias <alias> -file gd_bundle-g2-g1.crt -keystore <keystore.jks>
root certificate: keytool -import -trustcacerts -alias <alias> -file e2e56xxxxf40c7.crt -keystore <keystore.jks>
Then I created the pcks keystore this way:
keytool -importkeystore -srckeystore <keystore.jks> -destkeystore <keystore.p12> -srcstoretype JKS -deststoretype PKCS12 -deststorepass <password> -srcalias <src alias> -destalias <dest alias>
After that, my spring boot config to install the certificate is:
After comments on this question I changed to use the JKS and removed ciphers.
server:
port: 8443
ssl:
enabled: true
key-store-type: JKS
key-store: classpath:asgard_keystore.jks
key-store-password: generated
key-alias: asgard
After installing all those to the p12, the server started okay, but any requests to the server would yield: err_ssl_version_or_cipher_mismatch or SSL_ERROR_NO_CYPHER_OVERLAP
Capturing that in wireshark just said Alert 21 using TLS 1.2 Handshake Failure (40).
I'm using undertow as a server. I don't remember if I used the domain in the name and last name field of the CSR.
Decoding my CSR using digicert tool I got:
Common name
<my domain>
Organization
<my org>
Organizational unit
<my city>
City/locality
<my city>
State/province
<my estate>
Country
<my country>
Signature algorithm
SHA256
Key algorithm
RSA
Key size
2048
Seems I'm doing everything exactly like every single tutorial, and every time something fails :(
As per the comment on the question, the keytool -list calls:
keytool -list for the .jks:

I have removed parts of the response that I find not relevant. I found it weird that the pkcs (.p12) file reported as being a jks type.
Also, the files that I received form the certificate authority are:
5<removedhex>6b1b.crt
gd_bundle-g2-g1.crt
gdig2.crt.pem
The gd_bundle contains 3 certificates -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- three times. The other two are just one.
You have told java to use the certificate with an alias of asgard. I can see in your .p12 dump that "asgard" is actually a CA. Look at the owner:
Alias name: asgard
Creation date: Dec 14, 2018
Entry type: trustedCertEntry

I'm guessing that you actually want to tell spring to load your .jks file and specify an alias of codesigncert.
Also, delete your ciphers and enabled-protocols properties unless you have a good reason to override what spring sets up as defaults. Spring keep their defaults up to date with the latest security bulletins.
Finally, change your keystore password because the whole internet now knows what it is :)
I have solved the problem.
After fiddling A LOT with each certificate, I have found out that GoDaddy issues the certificate response and 2 equal intermediate certificates. Both come in the download package and there is no root certificate in there.
What happened is that I had a self signed dummy key, as stated in the comments and I didn't knew that I had to import the server certificate (the certificate response) with the same alias as my private key. I was importing with another alias thinking it was something else. My private key would remain self signed and not validated.
The errors I was getting about ciphers were because I was telling spring to use a certificate that was not a private key. Those don't support decoding the handshake.
Another problem that I faced is that godaddy doesn't provide the root certificate in the bundle you download. I was trying to add two intermediates, while the root was avaliable at a repository they had. After downloading and importing the correct root certificate, then I was able to import the private key validation certificate to the same alias as my dummy key.
So the solutin was simply to start with the JKS keystore used to create the CSR (one that contains only the private key I generated). Then add to it the root and intermediate certificates, and finally add the server cert (the one with the hex name), with the same alias as the private key.
I am trying to connect to a server with a Java Http client to make a web service call. If I turn net debugging on with the below code..
System.setProperty("javax.net.debug", "all");
I am seeing that certificates from Entrust seem to be added as trusted certificates. Among those added were the below...
adding as trusted cert:
Subject: CN=Entrust.net Certification Authority (2048), OU=(c) 1999 Entrust.net Limited, OU=www.entrust.net/CPS_2048 incorp. by ref. (limits liab.), O=Entrust.net
Issuer: CN=Entrust.net Certification Authority (2048), OU=(c) 1999 Entrust.net Limited, OU=www.entrust.net/CPS_2048 incorp. by ref. (limits liab.), O=Entrust.net
Algorithm: RSA; Serial number: 0x3863def8
Valid from Fri Dec 24 12:50:51 EST 1999 until Tue Jul 24 10:15:12 EDT 2029
It seems as if the server is using a cert from Entrust because I also see in the debug...
main, READ: TLSv1 Handshake, length = 2649
*** Certificate chain
chain [0] = [0] Version: 3
SerialNumber: 1356119177

Start Date: Wed Jul 15 11:50:20 EDT 2015
Final Date: Sun Jul 15 18:27:04 EDT 2018
And yet during the handshake process I get the below exception...
***
Caught: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException:
PKIX path building failed: java.security.cert.CertPathBuilderException:

I was able to fix this by adding server certificate to my java client (jre's cacerts and jssecacerts).
If we add a certificate to java client this way we are asking our jre to trust this server's certificate.
echo | openssl s_client -showcerts -connect www.xyz.com:443 2>&1 |
sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/cert.pem
#cacerts
keytool -import -alias certname -file /tmp/cert.pem -keystore
/usr/java/jdk1.8.0_45/jre/lib/security/cacerts -storepass changeit
#jssecacerts(Normally we remove this file)
keytool -import -alias certname -file /tmp/cert.pem -keystore
/usr/java/jdk1.8.0_45/jre/lib/security/jssecacerts -storepass changeit
If this piece of client code is executed via application server , please restart your application server.
Make sure you have openssl, keytool in enviornment variables and change your respective JAVA_HOME location.
I got around this problem by creating a Trust Manager which accepts the server's certificate and pointed my Apache HttpClient to use that Trust Manager...
private class TrustAll implements X509TrustManager
{
public void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException
{
}
public void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException
{
}
public X509Certificate[] getAcceptedIssuers()
{
return new X509Certificate[0];
}
}
TrustManager[] trustArray = [new TrustAll()] as TrustManager[]
SSLContext ctx = SSLContext.getInstance("TLSv1");
ctx.init(null, trustArray, null);
// create an http client builder
HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
httpClientBuilder.setSslcontext(ctx)
httpclient = httpClientBuilder.build();
I have a class that will download a file from a https server. When I run it, it returns a lot of errors. It seems that I have a problem with my certificate. Is it possible to ignore the client-server authentication? If so, how?

The problem appears when your server has self signed certificate. To workaround it you can add this certificate to the list of trusted certificates of your JVM.
In this article author describes how to fetch the certificate from your browser and add it to cacerts file of your JVM. You can either edit JAVA_HOME/jre/lib/security/cacerts file or run you application with -Djavax.net.ssl.trustStore parameter. Verify which JDK/JRE you are using too as this is often a source of confusion.
See also: How are SSL certificate server names resolved/Can I add alternative names using keytool? If you run into java.security.cert.CertificateException: No name matching localhost found exception.
Here's what reliably works for me on macOS. Make sure to replace example.com and 443 with the actual hostname and port you're trying to connect to, and give a custom alias. The first command downloads the provided certificate from the remote server and saves it locally in x509 format. The second command loads the saved certificate into Java's SSL trust store.
openssl x509 -in <(openssl s_client -connect example.com:443 -prexit 2>/dev/null) -out ~/example.crt
sudo keytool -importcert -file ~/example.crt -alias example -keystore $(/usr/libexec/java_home)/jre/lib/security/cacerts -storepass changeit
I had the same issue with a valid signed wildcard certificate from symantec.
First try running your java application with -Djavax.net.debug=SSL to see what is really going on.
I ended up importing the intermediate certificate which was causing the cert chain to break.
I downloaded the missing intermediate cert from symantec (you can see the download link to the missing cert in the ssl handshake log: http://svrintl-g3-aia.verisign.com/SVRIntlG3.cer in my case).
And I imported the cert in the java keystore. After importing the intermediate certificate my wildcard ssl cert finally started working:
keytool -import -keystore ../jre/lib/security/cacerts -trustcacerts -alias "VeriSign Class 3 International Server CA - G3" -file /pathto/SVRIntlG3.cer
Export the SSL certificate using Firefox. You can export it by hitting the URL in the browser and then select the option to export the certificate. Let's assume the cert file name is your.ssl.server.name.crt
Go to your JRE_HOME/bin or JDK/JRE/bin
Type the command
keytool -keystore ..\lib\security\cacerts -import -alias your.ssl.server.name -file .\relative-path-to-cert-file\your.ssl.server.name.crt
Restart your Java process

Quoting from No more 'unable to find valid certification path to requested target'
when trying to open an SSL connection to a host using JSSE. What this usually means is that the server is using a test certificate (possibly generated using keytool) rather than a certificate from a well known commercial Certification Authority such as Verisign or GoDaddy. Web browsers display warning dialogs in this case, but since JSSE cannot assume an interactive user is present it just throws an exception by default.
Certificate validation is a very important part of SSL security, but I am not writing this entry to explain the details. If you are interested, you can start by reading the Wikipedia blurb. I am writing this entry to show a simple way to talk to that host with the test certificate, if you really want to.
Basically, you want to add the server's certificate to the KeyStore with your trusted certificates
Try the code provided there. It might help.
This solved my issue,

problem: I was trying to connect to an endpoint(https://%s.blob.core.windows.net) using a simple java class(main method).
So I was getting this certification issue as mentioned above, in the question.
Solution:
Get the certificate using a browser(chrome). To do this paste your endpoint URL in the browser and enter. Now you will see a lock icon, click on that -->certificate--> details --> copy to files--> download it.
open the cmd(i am using windows) as admin and then navigate to the directory where you have downloaded the .cer file.
3.(Optional)If you are using multiple JDK in the same machine then change your JDK version the same as you are using in your application.
Now use the below command
keytool -import -alias mycertificate -keystore "C:\Program
Files\Java\jdk-11.0.5\lib\security\cacerts" -file myurlcrt.cer
Give the default password: changeit
Trust this certificate: yes
And you are done.
Thanks!
I was able to get it working with code only, i.e. no need to use keytool:

The source of this error on my Apache 2.4 instance (using a Comodo wildcard certificate) was an incomplete path to the SHA-1 signed root certificate. There were multiple chains in the issued certificate, and the chain leading to a SHA-1 root certificate was missing an intermediate certificate. Modern browsers know how to handle this, but Java 7 doesn't handle it by default (although there are some convoluted ways to accomplish this in code). The result is error messages that look identical to the case of self-signed certificates:
Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
at sun.security.provider.certpath.SunCertPathBuilder.engineBuild(SunCertPathBuilder.java:196)
at java.security.cert.CertPathBuilder.build(CertPathBuilder.java:268)
at sun.security.validator.PKIXValidator.doBuild(PKIXValidator.java:380)
... 22 more
In this case, the "unable to find valid certification path to requested target" message is being produced due to the missing intermediate certificate. You can check which certificate is missing using SSL Labs test against the server. Once you find the appropriate certificate, download it and (if the server is under your control) add it to the certificate bundle. Alternatively, you can import the missing certificate locally. Accommodating this issue on the server is a more general solution to the problem.
For Windows only, follow these steps:
In Chrome go to settings.
In Settings click show advance settings.
Under HTTPS/SSL Click on Manage Certificates.
Export Your Certificate.
In Windows searchs (Pressing windows key on keyboard) type java.
Select (Configure Java) Option Which will open Java Control Panel
Select Security tab in Java Control Panel
Select Manage Certificates
Click Import
Under (User) tab selected and certificate type as (Trusted Certificates)
Click import button and browse to downloaded certificate and import it.
There is a lot of way to solve this...
One way is set the TrustStore certificates in a keystore file and put it in the path of the application, and set these system properties in the main method:
public static void main(String[] args) {
System.setProperty("javax.net.ssl.trustStore", "trust-store.jks");
System.setProperty("javax.net.ssl.trustStorePassword", "TrustStore");
...
}
Other way is place the keystore as resource file inside the project jar file and load it:
public static SSLContext createSSLContext(String resourcePath, String pass) throws NoSuchAlgorithmException, KeyStoreException, IOException, CertificateException, UnrecoverableKeyException, KeyManagementException {
// initialise the keystore
final char[] password = pass.toCharArray();
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(ThisClass.class.getResourceAsStream(resourcePath
), password);
// Setup the key manager factory.
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, password);
// Setup the trust manager factory.
TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
tmf.init(ks);
SSLContext sslc = SSLContext.getInstance("TLS");
sslc.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
return sslc;
}
public static void main(String[] args) {
SSLContext.setDefault(
createSSLContext("/trust-store.jks", "TrustStore"));
...
}
In windows you can try this solution too: https://stackoverflow.com/a/59056537/980442
I created the keystore file from a Certificate authority CA .crt file in this way:
keytool -import -alias ca -keystore trust-store.jks -storepass TrustStore -trustcacerts -file ca.crt
FYI: https://docs.oracle.com/javadb/10.8.3.0/adminguide/cadminsslclient.html
For those who like Debian and prepackaged Java:
sudo mkdir /usr/share/ca-certificates/test/ # don't mess with other certs
sudo cp ~/tmp/test.loc.crt /usr/share/ca-certificates/test/
sudo dpkg-reconfigure --force ca-certificates # check your cert in curses GUI!
sudo update-ca-certificates --fresh --verbose
Don't forget to check /etc/default/cacerts for:
# enable/disable updates of the keystore /etc/ssl/certs/java/cacerts
cacerts_updates=yes
To remove cert:
sudo rm /usr/share/ca-certificates/test/test.loc.crt
sudo rm /etc/ssl/certs/java/cacerts
sudo update-ca-certificates --fresh --verbose
UPDATE: That a reboot helped was coincidental (I hoped so, hooray!). The real cause of the problem was this: When Gradle is directed to use a specific keystore, that keystore must also contain all the official root certificates. Otherwise it cannot access libraries from regular repositories. What I had to do was this:
Import the self-signed certificate:
keytool -import -trustcacerts -alias myselfsignedcert -file /Users/me/Desktop/selfsignedcert.crt -keystore ./privateKeystore.jks
Add the official root certificates:
keytool -importkeystore -srckeystore <java-home>/lib/security/cacerts -destkeystore ./privateKeystore.jks
Maybe the Gradle daemon also got in the way. Might be worth killing all running daemons found with ./gradlew --status if things start looking bleak.
ORIGINAL POSTING:
Nobody will believe this, I know. Still, if all else fails, give it a try:
After a reboot of my Mac the problem was gone. Grrr.
Background:
./gradlew jar kept giving me "unable to find valid certification path to requested target"
I am stuck with a self-signed certificate, saved from browser, imported in privateKeystore.jks. Then instructed Gradle to work with privateKeystore.jks:
org.gradle.jvmargs=-Djavax.net.debug=SSL -Djavax.net.ssl.trustStore="/Users/me/IntelliJ/myproject/privateKeystore.jks" -Djavax.net.ssl.trustStorePassword=changeit
As mentioned, this only worked after a reboot.
Had the issue like this image.
Tried a few solutions.
But found that even if it's same project, when it's on other one's working place, it's totally fine. No extra settings needed. So we guessed it's an enviroment issue. We tried changing JDK version, IDE but didn't work. it took about 4 hours for investigation, until we tried the top-rated answer. I didn't find the error mentioned in that answer but I found via my browser about HTTP URL (lock) that there was a certification of Charles. Then I realized my charles was on all the time. As long as I turned that off, it's working all fine.
So I left my experience that could be helpful for your case.
This can also be caused by using GoDaddy certs with Java 7 that are signed using SHA2.
Chrome and all other browsers are starting to deprecate SSL certs that are signed using SHA1, as it's not as secure.
More info on the issue can be found here, as well as how to resolve it on your server if you need to now.
AVG version 18.1.3044 (with Windows 10) interfer with my local Spring application.
Solution: enter in AVG section called "Web and email" and disable the "email protection".
AVG block the certificate if the site isn't secure.
I had the same problem with the certificates error and it was because of SNI: the http client that I used didn't have SNI implemented. So a version update did the job
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.3.6</version>
</dependency>
Download the certificate from Nexus3 Browser (click on the lock-pad for View Site Information in case of Edge broser)
Click on Connection is secure
Click on the certificate details
Click on Copy To file (it opens up export certificate wizard)
Choose Base-64 encoding
Browse and select a download location and file-name (let’s say mycert)
Open cmd
Goto the download location and execute the below command
keytool -import -alias mycert -keystore "<<your-JAVA_HOME-directory>>\jre\lib\security\cacerts" -file mycert.cer
Restart the machine
Execute maven build again.
And if you are here in 2022 and are on mac follow this
1. Download the certificate.
echo -n | openssl s_client -connect <ServerName>:<PORT> -servername <ServerName> \
| openssl x509 > /tmp/<ServerName>.cert
2. Find your JDK path by executing the command.
/usr/libexec/java_home
3. Now import the cert into the cert-store of jdk.
sudo keytool -import -alias mycertificate -keystore "<JDK_HOME>/lib/security/cacerts" -file /tmp/<ServerName>.cert
You have two options, import the self-signed cert into java's keystore for each jvm the software will run on or try the non-validating ssl factory:
jdbc:postgresql://myserver.com:5432/mydatabasename?ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory
Make sure that the https://176.66.3.69:6443/ have a valid certificate.
you can check it via browser firstly if it works in browser it will work in java.
that is working for me
If getting this error in maven, or maven with TestNG :
download the certificate from the target website and install certificate on your machine (using keytool as suggested above, or on windows)
add the following content to the maven arguments (command line and/or IDE):
-Djavax.net.ssl.trustStore=C:\Users\me.keystore -Djavax.net.ssl.trustStorePassword=X
Where X is the password you used at the keytool step.
note : C:\Users\me.keystore should also be set to match your machine.
For instance :
mvn -ea -Dtestng.dtd.http=true -Djavax.net.ssl.trustStore=C:\Users\me\.keystore -Djavax.net.ssl.trustStorePassword=X -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Dmaven.wagon.http.ssl.ignore.validity.dates=true -Dcucumber.features=src/test/resources -Dcucumber.glue=com.myapp -Dcucumber.filter.tags="#MY_TEST"
In my case I'm running MacOs High Sierra with Java 1.6. The cacert file is in a different location than referenced above in Gabe Martin-Dempesy's answer. The cacert file was also already linked to another location (/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/lib/security/cacerts).
Using FireFox, I exported the certificate from the web site in question to a local file called "exportedCertFile.crt". From there, I used keytool to move the certificate into the cacert file. This fixed the problem.
bash-3.2# cd /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/security/
bash-3.2# keytool -importcert -file ~/exportedCertFile.crt -alias example -keystore cacerts -storepass changeit
first Download the ssl certificate then you can go to your java bin path execute the below command in the console.
C:\java\JDK1.8.0_66-X64\bin>keytool -printcert -file C:\Users\lova\openapi.cer -keystore openapistore
In my case I had both keystore and truststore having the same certificate so removing truststore helped. Sometimes the chain of certificates can be an issue if you've multiple copies of certificates.
As original question was - how to ignore the cert error, here is solution for those using SpringBoot and RestTemplate
#Service
public class SomeService {
private final RestTemplate restTemplate;
private final ObjectMapper objectMapper;
private static HttpComponentsClientHttpRequestFactory createRequestFactory() {
try {
SSLContextBuilder sslContext = new SSLContextBuilder();
sslContext.loadTrustMaterial(null, new TrustAllStrategy());
CloseableHttpClient client = HttpClients.custom().setSSLContext(sslContext.build()).setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE).build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(client);
return requestFactory;
} catch (KeyManagementException | KeyStoreException | NoSuchAlgorithmException var3) {
throw new IllegalStateException("Couldn't create HTTP Request factory ignore SSL cert validity: ", var3);
}
}
#Autowired
public SomeService(RestTemplate restTemplate, ObjectMapper objectMapper) {
this.objectMapper = objectMapper;
this.dimetorURL = dimetorURL;
restTemplate.setRequestFactory(createRequestFactory());
}
public ResponseEntity<ResponseObject> sendRequest(RequestObject requestObject) {
//...
return restTemplate.exchange(url, HttpMethod.GET, ResponseObject.class);
//...
}
}
This is what worked for me on macOS. Replace server-name and server-port with your own.
Run these two commands on your terminal.
Download certificate from the remote server
openssl x509 -in <(openssl s_client -connect server-name:server-port -prexit 2>/dev/null) -out ~/server-name.crt
Import cert to Java keystore
sudo keytool -importcert -file ~/server-name.crt -alias server-name -keystore $JAVA_HOME/jre/lib/security/cacerts -storepass changeit
Restart your application and the certs errors should go away!
This works on any OS you just need JDK installed :
Download the certificate from the remote server :
keytool -printcert -rfc -sslserver <your remote server hostname> > /tmp/remorte-cert.crt
Import the certificate to your JDK keystore :
keytool -importcert -file /tmp/remorte-cert.crt -alias <an alias for your remote server> -storepass changeit -keystore "${JAVA_HOME}/lib/security/cacerts" -noprompt
