The signature is the base64url-encoded HMAC of the first two parts:

base64UrlEncode(HMACSHA256(base64UrlEncode(header) + '.' + base64UrlEncode(payload), key))

The encoded header and encoded payload are joined with a period, undergoes HMAC with the token signing key, and then the entirety is encoded.
