'Websphere Encryption getting java.security.InvalidKeyException: Illegal key size Error

Was trying to encrypt string and pass back to front end as byte array in IBM Websphere. Implementation as per following:

        import sc.core.utils.CryptoUtil;

        String msgKey = CryptoUtil.randomString();
        String salt = CryptoUtil.generateSaltKey(); 
        String passphrase = CryptoUtil.getHashSHA512(msgKey); 
        byte[] cipherText = CryptoUtil.encryptWithAlias(nrRecord.getBytes(), passphrase, salt, "CDC");

However, I am getting following error message when trying to run the application hosted on webshpere:

java.security.InvalidKeyException: Illegal key size

WHen I ran as normal Java application, it works fine. Have tried this solution to set configuration on websphere but to no futile.

Any ideas? Thanks!

Witch IBM JDK version is Websphere using. If it is not one of the latest ones I think you would need to install the unrestricted policy files in the Websphere JDK.

How do I install the unrestricted SDK policy files in WebSphere Application Server from IBM.com? https://www.youtube.com/watch?v=Nz6vJCqvDrc

You can download the unrestricted policy files from the following site: https://www-01.ibm.com/marketing/iwm/iwm/web/pickUrxNew.do?source=jcesdk

I hope this helps

Best Regards
