Sign a JWS token::

>>> from jwcrypto import jwk, jws
>>> from jwcrypto.common import json_encode
>>> key = jwk.JWK.generate(kty='oct', size=256)
>>> payload = "My Integrity protected message"
>>> jwstoken = jws.JWS(payload.encode('utf-8'))
>>> jwstoken.add_signature(key, None,
...                        json_encode({"alg": "HS256"}),
...                        json_encode({"kid": key.thumbprint()}))
>>> sig = jwstoken.serialize()

Verify a JWS token::

>>> jwstoken = jws.JWS()
>>> jwstoken.deserialize(sig)
>>> jwstoken.verify(key)
>>> payload = jwstoken.payload
