bouncy-gpg VS sop-java

That's why I decided to create PGPainless. Originally, I was looking for other alternatives and stumbled across a library called bouncy-gpg, but I quickly figured that it was not suiting my needs and decided to go my own way. Nevertheless, bouncy-gpg heavily influenced PGPainless' development, especially in the early phases.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 What happens on your Mac if you add the `--openpgp` option when encrypting the file? (i.e. `gpg --openpgp -e -r max test`) This was a suggestion that seemed to work for someone else that says they encountered a "unknown packet type encountered: 20" error. See: https://github.com/neuhalje/bouncy-gpg/issues/64#issuecomment-913516574 According to my version of GnuPG (2.2.20), the `--openpgp` option does the following: ``` - --openpgp Reset all packet, cipher and digest options to strict OpenPGP behavior. Use this option to reset all previous options like --s2k-*, --cipher-algo, --digest-algo and --compress-algo to OpenPGP compliant values. All PGP workarounds are disabled. ``` I'd be interested to see if this fixes your problem. -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEOPlkN8g6yI4ot6lSV9pX2VF+b4YFAmJSnXIACgkQV9pX2VF+ b4bY9g/8DtI2yObUYCXFHbofqFVB3sPHXtt7BGL93U7LtQgSffWppSYEsYvWFEk8 2En2bSM8o4ubtUWDjjGOx09Vw6Tu56OWSBoRm+wO9wU65JrZxhbtbSXD2HCuzW3X f8Kx8IrBnC2ZAUxx4X9QXjt/6dZRLNwJdPf3UQJ58gj15cvgGDER7yW0JeiLwv5A 4xuBrUzff/BliFu0xJ5/0ClOg4JKczPoiMx1Qy5h/gKw5MbMk3IG4oXwoDd0zND2 V/QGe6UMxcB4Jos8zIV10jI1yDOvxhKeDmQVJiZuztj5wRzSNY/edLrZklh5GV20 H150TUPXOYKuHc2PdXOV3zufED1dyD5UFnNpjTD5hdyq0yeJeRGIZrA3SlKGhB4L VonpEGhyJ88ZJQUvhdffBvf4S3uKQJUhQcZT5ycTM2rCoHQrTOh4N1xnqz0D+hzw X0qfMszmWjHYSuC+g4AUDeuhsB6ikLJLNu3IGVS/WY68hXW3cWrKHjzoCbsruN/s IemjANQ2rgWS2v2KmJJ6WYyR3Gi2NNci9WXHF/gXcJuYohDHTWX6DHzyjDep3Tcn EBGTutpRvXDh7vQKUtEoNDq/c/A/smVuce03PPYr19x0jSREYevPClP3tP53/enf 0o6EU+lCtJYgRH7EvC5uMiIh75KpXWFcnuFqRFLprW5ZQV1i7eI= =KvC8 -----END PGP SIGNATURE-----

PGPainless provides both a programmatic adaption of this API, as well as a CLI app. This means that if your app needs to do basic OpenPGP operations, you can simply depend on a module called sop-java which defines the programmatic SOP interface (here is a guide). This interface can be implemented by any OpenPGP library, but PGPainless provides its own implementation through the module pgpainless-sop. That way you can benefit from a super simple-to-use OpenPGP API while not being locked in to use PGPainless.
