I wonder if/when a C or C++ bindings to this library will be made. It would be nice to have some alternative to GpgME.

There is also sequoia, with an explicit goal of being easy to link to C. If you can bear the license.

For those wondering, the license for Sequoia is GPLv3.

The instructions aren't very straightforward, but you can compile Go code (which GopenPGP is) into a C archive https://golang.org/cmd/go/#hdr-Build_modes

This[0] (from Alistair Crooks (NetBSD), who constantly amazes me) might fit the bill?

I’m not sure I understand why Protonmail forked the Go crypto library here. Did they fork the entire thing and make substantial changes/updates throughout, or did they just make changes to the PGP implementation available in Go/crypto?

Go/crypto already implements elliptic curve cryptography[1], so I’m curious which specific elliptic curve primitives (or algorithms) they added to their fork.

They changed defaults. 570d0c5fa7ef500786f15958b39af43af3359719 is interesting: "Add secp256k1 / x25519 / brainpool curves to openpgp".

Go wanted to deprecate OpenPGP support. But, it looks as if they have walked that back a lot:

https://github.com/golang/go/issues/30141

"We will be deprecating the packages listed above, except openpgp/, otr/ and xts/.

I'll update the proposal and send a CL shortly."

iOS/macOS developers have an alternative with https://github.com/krzyzanowskim/ObjectivePGP that is tailored to the Apple platforms.
