We’ve been running Kleopatra PGP decryption inline with an SSIS package to process bulk files for awhile. It had been running fine until recently when it started to fail when decrpyting some of our files not not others.

Under the cmd line these files failed due to “Unknown Error”.

When using the Kleopatra client to decrypt/verify we get the error: File…..contains certificates and can’t be decrypted or verified.”

We haven’t had any updates to our encryption processes and Kleopatra seems to still be decrypting a subset of our files. Are there any troubleshooting steps I can employ here?
