OpenPGP.js is a pure JavaScript implementation of the OpenPGP protocol (RFC 9580), maintained by Proton Mail. It lets applications encrypt, decrypt, sign, and verify data and manage PGP keys in browsers, Node.js, and Deno without requiring native GPG installations.

Use cases

• encrypt and decrypt messages with PGP keys in the browser
• sign and verify cleartext or detached signatures in JavaScript
• generate and revoke OpenPGP key pairs
• add end-to-end encryption to a webmail client
• encrypt files with a password in Node.js
• implement PGP encryption in a browser extension

When to choose

• you need OpenPGP encryption/signing in JavaScript without native dependencies
• you're building a browser app, extension, or Node.js server that handles PGP email or messages
• you want a well-audited, actively maintained library implementing the latest RFC 9580

When to avoid

• you need PGP in a non-JavaScript environment or want native GPG performance
• you need general-purpose symmetric encryption rather than the OpenPGP format
• your runtime lacks Web Cryptography (SubtleCrypto) or Web Streams support
