I have a GPG certificate from someone used for email
-----BEGIN PGP PUBLIC KEY BLOCK----- Version: GnuPG/MacGPG2 v2.0.14 (Darwin)
I would like to import that into Windows Certificate Manager
So I can use it in Thunderbird, which uses Certificate Manager
Which can only import
*.crt, *.cert, *.cer, *.pem, *.der.
I couldn't find anything relevant https://duckduckgo.com/?q=convert+gpg+to+crt
I found this
But I don't have access to OpenPGP2SSH.
I found MonkeySphere and compiled it from source, but it's giving an error.
