Is it possible to sign a PDF with an OpenPGP key generated by Thunderbird ?

Hi everyone,

I was wondering if you know a way to use the generated OpenPGP key created trough Thunderbird to sign PDF's ?

(Devuan distro)

Thanks.

Thank you all for your quick reactions !!

To summarize if I want to use the PDF built-in signing I will need to convert my OpenPGP into a X.509 cert otherwise I can simply use the OpenPGP file signing

I want to stick to the UNIX Philosophy especially:

Write programs that do one thing and do it well.

So I will use the OpenPGP signing tool :)

Thanks !

OpenPGP is kind of like the opposite of that - it does a lot of things, and none of them particularly well. To quote:

PGP does a mediocre job of signing things, a relatively poor job of encrypting them with passwords, and a pretty bad job of encrypting them with public keys. PGP is not an especially good way to securely transfer a file. It’s a clunky way to sign packages. It’s not great at protecting backups. It’s a downright dangerous way to converse in secure messages.

minisign is more in the UNIX spirit.
