• The most popular and robust Java 7+ and Android library for JSON Web Tokens (JWT)
• Supports all standard signature (JWS) and encryption (JWE) algorithms, including recent developments such secp256k1, ECDH-1PU and XC20P
• Open source Apache 2.0 license

Check out the library homepage for more info and examples.

Create, parse and process:

• JOSE secured objects:
  • With compact URL-safe serialisation:
    • JSON Web Signature (JWS) objects
    • JSON Web Encryption (JWE) objects
    • Unsecured (alg=none) JOSE objects
    • Signed, encrypted and unsecured JSON Web Tokens (JWTs)
• With JSON serialisation:
  • JWS JSON objects with one or more signatures
  • JWE JSON objects with one or more recipients
• JSON Web Key (JWK) objects and JWK sets

The library handles the following 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, ES512 and EdDSA
• Key encryption with RSAES-PKCS1-V1_5: RSA1_5 (deprecated)
• Key encryption with RSAES OAEP: RSA-OAEP, RSA-OAEP-256 and RSA-OAEP-512
• 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
• Public key authenticated encryption utilising the One-Pass Unified Model for Elliptic Curve Diffie-Hellman key agreement: ECDH-1PU, ECDH-1PU+A128KW, ECDH-1PU+A128KW, ECDH-1PU+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
• Content encryption with extended nonce ChaCha20-Poly1305: XC20P
• JWE Compression with DEFLATE.

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

• JCIP for concurrency annotations
• (shaded) GSon for parsing and serialisation of JSON
• (optional) BouncyCastle as an alternative JCA provider and for selected key and certificate utilities. Must not be imported together with the BouncyCastle FIPS provider!
• (optional) BouncyCastle FIPS as a FIPS 140-2, Level 1 compliant JCA provider. Must not be imported together with the plain BouncyCastle provider!
• (optional) Tink for OKP generation, EdDSA with Ed25519, ECDH with X25519 and content encryption with XC20P.

For Maven add:

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

where [ version ] is the latest stable version.

To work around missing class errors when using this library with ProGuard and
R8 "full mode":

-dontwarn net.jcip.annotations.Immutable
-dontwarn net.jcip.annotations.ThreadSafe
-dontwarn com.google.crypto.tink.subtle.XChaCha20Poly1305

See issue #518 for details.
