I am trying to configure tomcat with the SSL on server (Because i need to make a request through https).
I followed these steps-:
1). generating a keystore
$Tomcat\bin>keytool -genkey -alias mkyong -keyalg RSA -keystore
c:\mkyongkeystore
Enter keystore password:
Re-enter new password:
What is your first and last name?
[Unknown]: yong mook kim
What is the name of your organizational unit?
//omitted to save space
[no]: yes
Enter key password for <mkyong>
(RETURN if same as keystore password):
Re-enter new password:
$Tomcat\bin>
2). configuring tomcat with keystore by adding a connector In server.xml
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"
keystoreFile="/var/lib/tomcat7/webapps/key/mykeystore"
keystorePass="password" />
then I tried to open the https://[host]:8443/
But its still shows This page can’t be displayed
But when I tried the same method for localhost then it worked.
Why its not working on server
Here are some quotes from Tomcat documentation on setting HTTPS:
Tomcat can use two different implementations of SSL:
the JSSE implementation provided as part of the Java runtime (since 1.4)
the APR implementation, which uses the OpenSSL engine by default....
As configuration attributes for SSL support significantly differ between APR vs. JSSE implementations, it is recommended to avoid auto-selection of implementation. It is done by specifying a classname in the protocol attribute of the Connector.
To define a Java (JSSE) connector, regardless of whether the APR library is loaded or not, use one of the following:
<!-- Define a HTTP/1.1 Connector on port 8443, JSSE NIO implementation -->
<Connector protocol="org.apache.coyote.http11.Http11NioProtocol"
port="8443" .../>
My understanding on that is that you should try to use a classname for the protocol attribute:
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
SSLEnabled="true" maxThreads="150" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"
keystoreFile="/var/lib/tomcat7/webapps/key/mykeystore"
keystorePass="password" />
I think better you can redirect the tomcat port to IIS,in IIS you can easily enable HTTPS.

We are running a spring boot application on tomcat server 8.5.5. We have security certificates and SSL configured for it to support https. Currently is uses TLSv1.2. Our payment gateway provider has plans to discontinue TLSv1.2 support and continue support for only TLSv1.3.
Hence we want to add TLSv1.3 support to our application server. Our connector block with the required ciphers for TLSv1.3 is below.
<Connector port="443" maxThreads="150" scheme="https" secure="true" SSLEnabled="true" keystoreFile="/home/ubuntu/ourkey.p9"
keystorePass="ourpass" clientAuth="false" keystoreType="keystore"
sslProtocol="TLSv1.2" sslEnabledProtocols="TLSv1.2+TLSv1.3" protocol="org.apache.coyote.http11.Http11NioProtocol" server="Web"
useServerCipherSuitesOrder="true"
ciphers="TLS_AES_256_GCM_SHA384,
TLS_CHACHA20_POLY1305_SHA256,
TLS_AES_128_GCM_SHA256,
TLS_AES_128_CCM_8_SHA256,
TLS_AES_128_CCM_SHA256,
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384,... other ciphers/>
We are using the JSSE implemetation and so far no concrete documntation could be found for tomcat. The official doc has the connector block as below:
<!-- Define an SSL Coyote HTTP/1.1 Connector on port 8443 -->
<Connector
protocol="org.apache.coyote.http11.Http11NioProtocol"
port="8443" maxThreads="200"
scheme="https" secure="true" SSLEnabled="true"
keystoreFile="${user.home}/.keystore" keystorePass="changeit"
clientAuth="false" sslProtocol="TLS"/>
Here the sslProtocol attribute has TLS which by defaults to TLS version 1.2. We tried it changing to TLSv1.3 but did not work. Also, as mentioned here tried adding the sslEnabledProtocol attribute. That did not work as well. We addded the necessary ciphers needed for a TLSv1.3 handshake to be successful.
How can we configure the server.xml connector block for it to support TLSv1.3 is what we are trying to figure out. Any inputs, hints would be helpful.
Use both sslProtocol="TLS" and sslEnabledProtocols="TLSv1.2+TLSv1.3".
That works for me (on tomcat 9 with java 13.0.1)
I have a SSL Certificate (Cert1.cer file)
I created a keystore file using
keytool -import -alias es-staging.cdac.in -keystore key2 -file Cert1.cer
I updated my server.xml with
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"
keystoreFile="/var/lib/tomcat7/webapps/key/key2"
keystorePass="changeit"
sslEnabledProtocols="TLSv1.2,TLSv1.1,TLSv1"
ciphers="TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_RC4_128_SHA, TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA256, TLS_RSA_WITH_AES_256_CBC_SHA,SSL_RSA_WITH_RC4_128_SHA"
/>
Then I Restarted the tomcat server
And tried to access https://52.39.134.231:8443/
My Browser(Mozilla FireFox) is showing
I tried to access "(Not secure) Try loading 52.39.134.231 using outdated security "
But its still redirecting me to same page
Where am I going wrong?
The error message says that Firefox and Tomcat don't have a mutual cipher they could agree on. Well, there are ciphers that both Tomcat and Firefox are supporting in your case, but those have been disabled in Firefox for security reasons.
The ciphers you configured are pretty strong and restricting. Are you sure that all of them are supported by the underlying JDK version?
I've deployed a number of SSL configurations, including both Tomcat (cacerts + keytool) and IIS (Windows Certificate Store + netsh http sslcert) so I'm familiar with these procedures.
Has anyone come up with a way to point Tomcat's SSL connector to a Windows Store (i.e. configuration, extension, plugin, etc.)? Just looking to centralize management of SSL deployments to one store, vs. having multiple stores.
According to the answer on "SSL enabling in Tomcat Windows server" you can specify keystore type as "Windows-My" in configuration of connector in server.xml, it worked for me on Tomcat 8.0.22 as well
<Connector port="8443"
protocol="org.apache.coyote.http11.Http11NioProtocol"
SSLEnabled="true"
maxThreads="150"
scheme="https"
secure="true"
keyAlias="<alias of the cert>"
keystoreFile=""
keystoreType="Windows-My"
clientAuth="false"
sslProtocol="TLS"
keepAliveTimeout="200000" />
<Connector port="8443"
protocol="org.apache.coyote.http11.Http11NioProtocol"
SSLEnabled="true"
maxThreads="150"
scheme="https"
secure="true"
keyAlias="<alias of the cert>"
keystoreFile=""
keystorePass=""
keystoreType="Windows-My"
clientAuth="false"
sslProtocol="TLS"
keepAliveTimeout="200000" />
keystoreFile and keystorePass has to be set to empty string. see my comment at bz.apache.org "BUG 56021"
If not set they will default to values that causes trouble.
keyAlias should be either the friendly name (if it has one) or the common name of the certificate.
It seems not possible. From tomcat 8 documentation https://tomcat.apache.org/tomcat-8.0-doc/ssl-howto.html
tomcat currently operates only on JKS, PKCS11 or PKCS12 format keystores.
Windows Store would require an specific connector similar to the 'WINDOWS-MY' of JSSE.
There is no reference in documentation to any plugin or connector to Windows Certificate Store.
While Dmitry's solution works on Tomcat 8.0, from Tomcat 8.5 onward there is a small caveat: you need to explicitly set JSSE as SSLImplementation. Hence the configuration becomes (considering also the new structure introduced in Tomcat 8.5):
<Connector port="8443"
sslImplementationName="org.apache.tomcat.util.net.jsse.JSSEImplementation"
scheme="https" secure="true" SSLEnabled="true">
<SSLHostConfig>
<Certificate certificateKeystoreType="Windows-MY"
certificateKeystoreFile=""
certificateKeyAlias="tomcat" />
</SSLHostConfig>
</Connector>
Alternatively, one can also set useOpenSSL="false" on the AprLifecycleListener.
We have some problems with SSO (single sign on) authentication. We use JASIG CAS and our implmentation is not working. It is allert "You are currently accessing CAS over a non-secure connection. Single Sign On WILL NOT WORK. In order to have single sign on work, you MUST log in over HTTPS." But we added the sertificate to Tomcat server.xml
our settings in server.xml
<Connector port="8443"
protocol="org.apache.coyote.http11.Http11NioProtocol"
SSLEnabled="true"
maxThreads="150"
scheme="https"
secure="true"
clientAuth="false"
sslProtocol="TLS"
keyAlias="myalias"
keystoreFile="C:\Program Files\Java\jdk1.8.0_65\bin\ssoServer.jks"
keystorePass="12345678" />
If you did add the cert, then why are you going over localhost and 8080?
I am implementing https project.So i just tried ssl connection with tomcat
i created the key and certificates using the following commands from the following site.
http://mircwiki.rsna.org/index.php?title=Configuring_Tomcat_to_Support_SSL
genrsa –des3 –out tomcatkey.pem 2048
req –new –x509 –key tomcatkey.pem –out tomcatcert.pem –days 1095 -config "c:/openssl/tomcatkey.pem"
So i got the certificate and key from the openssl commands.(i used the key as "pratap")
i put these 2 files in tomcat folder.
i changed the connector element 8443
<Connector
port="8443" maxThreads="200"
scheme="https" secure="true" SSLEnabled="true"
SSLCertificateFile="c:/tomcat7/tomcatcert.pem"
SSLCertificateKeyFile="c:/tomcat7/tomcatkey.pem"
clientAuth="optional" SSLProtocol="TLSv1" SSLPassword="pratap" />
when i run https://localhost:8443 it is running fine.
Now in eclipse i created the server of this and try to run from the eclipse
But it is showing the following error.
java.io.IOException: Keystore was tampered with, or password was incorrect
at sun.security.provider.JavaKeyStore.engineLoad(Unknown Source)
at sun.security.provider.JavaKeyStore$JKS.engineLoad(Unknown Source)
at java.security.KeyStore.load(Unknown Source)
i did not use keystore command at any where.
could any body give some light on this..Thank you..
You should read http://tomcat.apache.org/tomcat-5.5-doc/ssl-howto.html#Configuration.
BTW: "Keystore was tampered with, or password was incorrect" - this error means your keystore is crashed or you have used wrong password. If you use selfsigned cert remeber to create truststore.
You need to pass the keystore password into your connector configuration. Here is an example:
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
keystorePass="qwerty"
clientAuth="false" sslProtocol="TLS" />
If you want to use another keystore you need to create one:
keytool -genkey -alias tomcat -keyalg RSA -keystore /home/user/.keystore2
and use it in your configuration:
<Connector
port="8443" maxThreads="200"
scheme="https" secure="true" SSLEnabled="true"
keystoreFile="${user.home}/.keystore2" keystorePass="qwerty"
clientAuth="false" sslProtocol="TLS"/>
