• The most popular and robust Java library for JSON Web Tokens (JWT)
• All standard signature (JWS) and encryption (JWE) algorithms are supported, including secp256k1 used in Bitcoin and Ethereum
• Open source Apache 2.0 license

Check out the library homepage for more info and examples.

Create, serialise and process compact-encoded:

• Plain (unsecured) JOSE objects
• JSON Web Signature (JWS) objects
• JSON Web Encryption (JWE) objects
• JSON Web Key (JWK) objects and JWK sets
• Plain, signed and encrypted JSON Web Tokens (JWTs)

The less frequently used alternative JSON encoding is on the road map.

The library can handle all standard JOSE algorithms:

• HMAC integrity protection: HS256, HS384 and HS512
• RSASSA-PKCS1-V1_5 signatures: RS256, RS384 and RS512
• RSASSA-PSS signatures: PS256, PS384 and PS512
• EC signatures: ES256, ES256K, ES384 and ES512
• Key encryption with RSAES-PKCS1-V1_5: RSA1_5 (deprecated)
• 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: A128CGMKW, A192CGMKW and A256CGMKW
• Direct shared symmetric key encryption: 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
• Content encryption with AES_CBC_HMAC_SHA2: A128CBC-HS256, A192CBC-HS384, A256CBC-HS512, the deprecated A128CBC+HS256 and A256CBC+HS512 are also supported
• Content encryption with AES GCM: A128GCM, A192GCM and A256GCM
• JWE Compression with DEFLATE.

The Nimbus JOSE+JWT library requires Java 7+ and has minimal dependencies.

• JSON Smart for highly efficient parsing and serialisation of JSON.
• JCIP for concurrency annotations.
• [optional] BouncyCastle as an alternative JCA provider.

For Maven add:

<dependency>
    <groupId>com.nimbusds</groupId>
    <artifactId>nimbus-jose-jwt</artifactId>
    <version>[ version ]</version>
</dependency>

where [ version ] is the latest stable version.
