Hello all,   After upgrading my app for a customer from Mx4.4.3.1 to Mx6.9.1, I now get an error message "JCE cannot authenticate the provider BC". The message occurs when trying to encrypt a file to be put on an SFTP-server.   To add to the mix: I am familiar with Java, but I'm certainly no expert. Any help on what might be causing this would be greatly appreciated.   The following files are in my 'userlib': -          bcpg-jdk15on-150.jar -          bcpg-jdk16-145.jar -          bcpkix-jdk15on-150.jar -          bcprov-jdk15on-150.jar -          bcprov-jdk16-145.jar I tried removing them all, hoping Mendix packages this by default: the project won't compile. I tried using only the '-150' files: the project compiles but still generates the same error (these were added in the conversion to Mx6 somewhere, presumably by the Encryption module) I tried using only the '-145' files: the project won't compile (these were the ones that were in my Mx4 version of the project) I even tried using the '-155' files, the latest version of BouncyCastle: the project won't compile (this breaks the Encryption module)   For completeness, I have included the full stack trace below. Thanks in advance for any help provided.   Kind regards,   Ronald     The full stack trace: com.mendix.core.CoreException: com.mendix.core.CoreRuntimeException:
