Failed to decode base64 certificate - Encryption-at-Rest

[Obsidiannite21]

I'm attempting to enable encryption at rest. I created a PGP Certificate with emClient. This certificate works when encrypting / decrypting messages just fine. I copied the Public Key Block into the Encryption at reset configuration page and get Failed to decode base64 certificate. Operation failed (see attached). I've tried modifying the data I pasted by removing a few of the line breaks but that doesn't help. Any assistance would be appreciated.

Try removing the Version: header, it does not look valid.

The base64 seems to be invalid. Try generating the key using OpenPGP or Thunderbird.

The key was generated by emClient and worked fine, but I did as you suggested, using Thunderbird, and that key worked with Stalwart. Thank you.
