I have Java app that has remote db credentials in hibernate config file in JAR file. I want to encrypt password that if "simple" user would search for the password in would be not human readable.
I have seen Jasypt examples on the web, but there is Jasypt only for hibernate 4. There is no for hubernate 5.
Can I use Jasypt for hibernate 4 with hibernate 5?
Or maybe there is another solution? I know that placing login and password in JAR file is not safe, but thats the way my app is created.
Thanks in advance.
Place the password(s) in an external .properties file. To use the application in test-setup, you can place a properties file inside your project with fake/test credentials to a local database. For production you can place the secrets on the specific machine that needs to connect to the database.
Never put things you want to keep secret in the jar, source or repository.

I created a maven project which connects to a database . The problem I am facing is I have hardcoded the db username and password but I according to the requirement it should be dynamically read from a .txt file in local path.
Is there any possible way for this solution or any other strategy that I should follow.
Thanks in advance
The java.util.Properties class has several load-methods that is easy to use.
I have stored the password of MongoDB in spring.data.mongodb.password property in application.yml file in my spring boot project. I need to encrypt it so that it is not directly accessed by anyone. I do not intend to do any code changes for it but want to achieve it by some kind of spring boot configuration.
The properties file should never be accessible by anyone (who uses of course the app)... Given that for granted, then I guess you mean to the other people working on your project, in that case I guess a possible solution would be to use BCEncryptor to encode a password and store it either in the properties file or on a side DB and then decrypt it at the launch of the application, through a configuration class or XML.
In any other case you could create a side user in MongoDB giving that use only the permissions you want.
But still, I wouldn't really see the use of it, because if someone have access to the backend of your application...
The issue got resolved. The problem was with the jasypt version. I was using jasypt-3.0.0 and it worked on 2.0.0. The full steps of configuring jasypt in the project can be found here :
https://medium.com/#mail2rajeevshukla/hiding-encrypting-database-password-in-the-application-properties-34d59fe104eb
I have passed the key in application.yml itself as the 3 mentioned methods were not working in my case.
jasypt:
encryptor:
password: secretkey
I got a requirement in Spring boot. I a nearly beginner so kindly ignore my mistake.
Main requirement is I have to encrypt all application.properties data so even someone get access, not be able to read. I don't know whether it is possible or not, So let me know that also.
Why want to do this - I Application.properties hold lots of credentials for DB and Data for other service and some how any hackers get's the credentials then he/she will get other data too of DB and API keys. So doing it for security purpose. It is some finance project.
Requirement: I have Encrypted application.properties file present on S3 Bucket and have to download from there and decrypt the file at the starting of project and the project will load the data from that application.properties file.
I broke down the problem in download and Encryption/Decryption:
So I know how to download file in Maven from URL in specific folder. - Done
How to Decrypt application.properties file and use it to load Credential. - Answer Looking for!
I got the ways by using Jasypt Library in Spring boot but that encrypt the value only.
jasypt.encryptor.password=pass
encrypted.property=ENC(S3oSEyuNwaFBrwfoaNhqvauLAui9F+L9)
And in Any Java file I get the value:
#Value("${encrypted.property}")
private String property;
But that is not hiding any data as If i get the Jasypt then i can decrypt data on Online websites also. And it is also not hiding the keys.
So didn't find it working according to my requirement. So kindly help me in this problem.
We have to use ssl certificate for our rest web service which are created through springboot application.
Now, what I came to know that password is necessary in order to use a certificate. So we are changing our available .pem (without password) to .p12 (with password) using openssl. Now we have to provide spring this password.
Problem is the overhead which comes with introducing any new password.
We cannot hard-code this password in our application.properties due to bad design. So we are thinking of finding out the other ways to use password in application. So far I can think of below options. which one is better one and why?
Rather then setting password in application.properties, set it from java code. (I am not sure it will be set as environment variable or system variable)
use environment variable to store the password.
use any text file which stores the password (not preferred again due to bad design)
you can achieve your scenario in the following way.
i am posting sample example.\
In Properties File:
spring.datasource.url=${db.url}
spring.datasource.username=${db.username}
while starting the project,
you can give the following command:
java -jar -Ddb.url=jdbc:postgresql://localhost:5432/postgres -Ddb.username=postgres sample.0.0.1-SNAPSHOT.jar(your jar name)
option 3 seems feasible, but instead of storing it in a plain text file, you can encrypt the file, and put a decryption function in the application when reading the file.
For the provided options, i would go with the option 2, by using environment variables it will be easier to provide and change the password even in containerized environments and clouds.
But you can also consider other options, like using a safe k-v storage like Hashicorp Vault or etcd.
Note that using Vault or etcd, you can also provide and change the certificate dynamically, instead of shipping it with the application.
I can think of 3 ways you can do it
1. You can define password property only in application.properties but pass
the value of the property during application startup.
java -jar -Dmyapp.password=YOUR_PASSWORD myapplication.jar
2. You can put encrypted passwords in application.properties and pass the decryption key during application startup. Jasypt plays very good with spring boot.
java -jar -Dmyapp.decryptKey=YOUR_KEY myapplication.jar
3. You can use spring vault
Recently I have gone through Jasypt API to secure the property file entries. As per Jasypt, in order to decrypt the entry in the property file that was enclosed with ENC(..), we need to use a secure password, a secret key, as shown below (Not a web application):
encryptor.setPassword("jasypt"); // could be got from web, env variable..
Of course we can configure such password using
org.jasypt.encryption.pbe.config.SimplePBEConfig setPassword()
But my question, if we extract the jar file, 3rd party could be able to find out the secret key. How could we ensure security in such cases?
Thanks in advance,
JK
secret key should be stored in environment variable outside the application.
For example, in your spring configuration file:
<bean id="environmentConfig" class=
"org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig"
p:passwordEnvName="APP_ENCRYPTION_PASSWORD" ...
Now, add APP_ENCRYPTION_PASSWORD in the env variable either in OS or app server.
