Nimbus JOSE + JWT

Create, parse and process JOSE and JWT objects:

A framework for secure application-specific processing of JWTs as well as generic (i.e. arbitrary payload) JOSE objects is provided.

The library implements all standard JWS and JWE algorithms:

JWS algorithms:

HMAC integrity protection: HS256, HS384 and HS512
RSA signatures: RS256, RS384, RS512, PS256, PS384 and PS512.
EC signatures: ES256, ES384 and ES512

JWE key management algorithms:

Key encryption with RSAES-PKCS1-V1_5: RSA1_5
Key encryption with RSAES OAEP: RSA-OAEP and RSA-OAEP-256
Key encryption with AES key wrap: A128KW, A192KW and A256KW
Key encryption with AES GCM key wrap: A128CGMKW, A192CGMKW and A256CGMKW
Direct encryption with a symmetric key: dir
Key Agreement with Elliptic Curve Diffie-Hellman Ephemeral Static: ECDH-ES, ECDH-ES+A128KW, ECDH-ES+A192KW and ECDH-ES+A256KW
Password-based encryption: PBES2-HS256+A128KW, PBES2-HS384+A192KW and PBES2-HS512+A256KW

JWE content encryption algorithms:

AES_CBC_HMAC_SHA2: A128CBC-HS256, A192CBC-HS384, A256CBC-HS512, the deprecated A128CBC+HS256 and A256CBC+HS512 are also supported
AES GCM: A128GCM, A192GCM and A256GCM

New JWA algorithms can be easily added. The library provides a set of simple interfaces to decouple the representation of JOSE / JWT objects from JWA crypto code for signing / verification or encryption / decryption. Multiple JCA providers, including hardware-based can be configured.

Implemented IETF standards:

Dependencies (see the Maven pom.xml for details):

JSON Smart for highly efficient parsing and serialisation of JSON.
Apache Commons IO.
JCIP for concurrency annotations.
[optional] The BouncyCastle.org JCA provider.
