Seeking assistance with javax.crypto.BadPaddingException: Unexpected padding

  • 1.  Seeking assistance with javax.crypto.BadPaddingException: Unexpected padding

    Posted 02/20/26 01:56 PM

    I am currently experiencing an issue with the 'javax.crypto.BadPaddingException: Unexpected padding' error, likely related to Java encryption/decryption processes.

    I have reviewed the available IBM community resources, but I was not able to find information addressing this specific problem within the context of IBM products or services.

    Could anyone provide guidance on troubleshooting this issue, particularly if you have experience dealing with it in a Java environment or using IBM's cryptographic tools? I'm eager to resolve this and ensure that any code or configurations used align with recommended security practices.

    This error occurred when I changed our System Certificate for our Organization, when I clicked on "Finish".

    Sincerely,

    Cindy
