• describes how the token signature can be checked
• payload (JSON > Base64 URL Encoded)
• Basically a map of whatever you want to put in it
• Some standard entries such as expiration
• signature (Binary > Base64 URL Encoded
• The actual digital signature
• made exclusively by the /oauth2/token endpoint
• If RSA, can be checked by anyone

jPrimeConf HTTP Signatures
• No “secret” ever hits the wire
• Signs the message itself
• Proves identity
• Prevents message tampering
• Symmetric or Asymmetric signatures
• IETF Draft
• https://tools.ietf.org/html/draft-cavage-http-signatures
• Extremely simple
• Does NOT eliminate beneﬁts of JWT

Speciﬁcation Reference

jPrimeConf Observations
• HTTP Signatures the only HTTP friendly approach
• Signatures does not solve the “Identity Load” problem
• OAuth 2 with JWT signiﬁcantly improves IDP load
• Plain OAuth 2
• HTTP Session-like implications
• OAuth 2 with JWT
• Signed cookie
• Signing key to the future
