GopenPGP is a high-level OpenPGP wrapper library for Go, developed by Proton Mail and built on a fork of the golang crypto library. It provides a simple API for key generation, encryption, decryption, signing, and verification, and is compatible with go-mobile.

Use cases

• encrypt and decrypt data with PGP keys or passwords in Go
• generate OpenPGP key pairs programmatically
• sign messages with detached, inline, or cleartext signatures
• add PGP encryption to a mobile app via go-mobile
• implement RFC 9580 compliant OpenPGP encryption
• verify signed PGP messages in a Go backend

When to choose

• you need an easy-to-use, well-maintained OpenPGP library in Go
• you want RFC 9580 support and security-audited crypto primitives
• you need PGP functionality on mobile platforms through go-mobile

When to avoid

• you need low-level control over OpenPGP packet handling
• you are not working in Go or a go-mobile target
• you require backward compatibility with the V2 API without migration
