GopenPGP V3 is a high-level OpenPGP cryptographic library developed by ProtonMail that provides a user-friendly API for common encryption and signing operations in Go, abstracting the complexity of the underlying OpenPGP standards and golang crypto primitives. This library lets developers perform key generation, message encryption and decryption, digital signing, and signature verification with straightforward functions that hide much of the boilerplate and nuance typically required when working directly with OpenPGP implementations. Built on top of a forked version of the Go crypto library, gopenpgp supports current OpenPGP RFC standards and includes examples for working with password-based encryption and PGP keys, as well as detached and inline signatures. Because it’s designed for broad use, the library also targets go-mobile compatibility, meaning it can support mobile app use cases alongside server and desktop tooling.
