Java JWT signature example

This is an example showing how to sign and verify JSON Web Tokens (JWT) with Tink.

It demonstrates the basic steps of using Tink, namely loading key material, obtaining a primitive, and using the primitive to do crypto.

The key material was generated with:

shell

$ tinkey create-keyset --key-template JWT_ES256 --out-format JSON \
    --out jwt_signature_test_private_keyset.json

Build and Run

Bazel

shell

$ git clone https://github.com/google/tink
$ cd tink/examples/java_src
$ bazel build ...
$ touch token.txt

$ ./bazel-bin/jwt/jwt_sign \
    ./jwt/jwt_signature_test_private_keyset.json example_audience token.txt

$ ./bazel-bin/jwt/jwt_generate_public_jwk_set \
    ./jwt/jwt_signature_test_private_keyset.json public_jwk_set.json

$ ./bazel-bin/jwt/jwt_verify \
    public_jwk_set.json example_audience token.txt
