*** DO NOT USE THIS UNLESS YOU KNOW WHY IT EXISTS ***

This fork modifies some of the key selection heuristics to handle very old PGP keys that don't have proper flags set.

You almost certainly do not want this - use the originals below:

go get github.com/ProtonMail/go-crypto

This module is backwards compatible with x/crypto/openpgp, so you can simply replace all imports of golang.org/x/crypto/openpgp with github.com/ProtonMail/go-crypto/openpgp.

A partial list of changes is here: ProtonMail#21 (comment).
