Empty securerandom.strongAlgorithms Security Property


When I am setting up as a application in Jenkins. The code works fine in local and other build environments. In Jenkins i am getting this error during the build and unit tests. Our application only needed external change is download JCE (Jave Crypto Extension) from oracle and replace the policy jars in JAVA_HOME/jre/lib/security folder. that I did. I can see log it is picking up those jars. Still i see below error. Do i need to do anything for secure random? SecureRandom.getInstanceStrong(); is causing the issue. any help?

Below is my java code.

public class AesGcmCipher {
    public static AesGcmCipher generate(BiConsumer<AesGcmCipher, SecretKey> consumer) {
        try {
            UUID cipherId = UUID.randomUUID();
            SecureRandom random = SecureRandom.getInstanceStrong();
            KeyGenerator keyGen = KeyGenerator.getInstance(AES);
            AesGcmCipher cipher = new AesGcmCipher(cipherId, secretKey, new Date());
            return cipher;
        } catch (NoSuchAlgorithmException ex) {
            LOGGER.error(msg);
            throw new CryptoException(msg, ex);
        }
    }
}

FYI Jenkins is running on java version "1.8.0_73". The code which is running perfectly on other machines with version 1.8.0_51 and 1.8.0_91


Solution

  • It should be an issue with your jdk. Could you verify this file $JAVA_HOME/jre/lib/security/java.security:

    securerandom.source=file:/dev/random
    securerandom.strongAlgorithms=NativePRNGBlocking:SUN
    

    This is my configuration, probably you'll need to reinstall JDK
