jose: Javascript Object Signing and Encryption and JSON Web Token library

[ apache, cryptography, library, program ] [ Propose Tags ]

An implementation of the Javascript Object Signing and Encryption (JOSE) and JSON Web Token (JWT; RFC 7519) formats.

The JSON Web Signature (JWS; RFC 7515) implementation is complete. JSON Web Encryption (JWE; RFC 7516) is not yet implemented.

All JWS algorithms (HMAC, ECDSA, RSASSA-PKCS-v1_5 and RSASSA-PSS) are implemented, however, the ECDSA implementation is is vulnerable to timing attacks and should therefore only be used for JWS verification.

The Crypto.JOSE.Legacy module is provided for working with the Mozilla Persona (formerly BrowserID) key format. Only RSA keys are supported - DSA keys cannot be used and must be handled as opaque objects.

jose - Javascript Object Signing and Encryption & JWT (JSON Web Token)

jose is a Haskell implementation of Javascript Object Signing and Encryption and JSON Web Token.

Encryption (JWE) is not supported but signing is supported. All key types and algorithms are supported, however, EC signing is currently vulnerable to timing attacks therefore its use is strongly discouraged (EC validation is safe).

Contributions are welcome.
