Symptoms


When attempting to use a security Provider (for example BouncyCastle) with a key larger then 128-bit within the JavaVM of the database the following error occurs:

ERROR
-----------------------
Exception in thread "Root Thread" java.security.InvalidKeyException: Illegal key size or default parameters
at javax.crypto.Cipher.a(DashoA12275)

It works fine when the used encryption key is 128-bit or less.
