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) formats.

Web Encryption (JWE) 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 version number tracks the IETF jose working group draft revisions. For now, expect breaking API changes on any version change except for the final (fourth) part being incremented.

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, but EC and symmetric key generation is not yet implemented.

Contributions are welcome.
