I Left My JWT in San JOSE

Published on

JSON Web Token (JWT) is emerging as the goto format for security tokens in next generation identity systems. This talk will provide a technical overview of JWT and it’s underpinnings, the JavaScript Object Signing and Encryption (JOSE) suite of specifications, and equip you with the knowledge and sills needed to talk about and use JWT and JOSE effectively. All the cool kids are doing it and JWT+JOSE recently won a Special European Identity Award for Best Innovation for Security in the API Economy at the 2014 European Identity & Cloud Conference.

I Left My JWT in San JOSE

  1. 1. `` Brian Campbell @__b_c Cloud Identity Summit 2014 http://www.slideshare.net/briandavidcampbell A technical overview of JSON Web Token (JWT) and JavaScript Object Signing and Encryption (JOSE)
  2. 2. Introductions http://blog.talkingidentity.com/2013/08/thanking-the-iam-venn-erables-in-my-own-way.html Me
  3. 3. More Introductions… Copyright © 2014 Ping Identity Corp. All rights reserved. 3https://twitter.com/itickr/status/354999490928857088 https://flic.kr/p/f6PKjB
  4. 4. • JavaScript Object Signing and Encryption (JOSE) – JSON Web Signature (JWS) • A way of representing content secured with a digital signature or MAC using JSON data structures and base64url encoding – JSON Web Encryption (JWE) • Like JWS but for encrypting content – JSON Web Key (JWK) • JSON data structures representing cryptographic keys – JSON Web Algorithms • Defines the use cryptographic algorithms and identifiers for JWS, JWE and JWK • JSON Web Token (JWT) – A compact URL-safe means of representing claims/attributes to be transferred between two parties – A JWT is a JWS and/or a JWE with JSON claims as the payload Copyright © 2014 Ping Identity Corp. All rights reserved. 4 JWT + JOSE Overview JWS JWE JWT JWK JSON
  5. 5. • Not even official RFCs yet but – Well regarded – And widely used: • OAuth • OpenID Connect • Mozilla Persona (ahem) • W3C Web Cryptography API • + more… Three nerds holding a blurry piece of paper they tell me is some kind of award for the JOSE & JWT work. http://www.kuppingercole.com/article/award2014 5 JWT + JOSE in the Wild
  6. 6. What’s in a Name? https://twitter.com/metadaddy/status/454422069199900672 JW*
  7. 7. Copyright © 2014 Ping Identity Corp. All rights reserved. 7 But you wouldn't name your child ‘Attila the Hun’ would you? "Attila, Scourge of God" http://en.wikipedia.org/wiki/File:Atilla_fl%C3%A9au_de_dieu.jpg I didn’t…
  8. 8. What would JOSE do? ‡ Call it JW-STEAK ‡ I reluctantly credit Paul Madsen with WWJD. Unless you are offended by it, in which case I’m not at all reluctant about blaming him. JW- JWS JWT JWE JWA JWK
  9. 9. Because who doesn’t like a good steak? Don Julio is a famous (to gringo tourists anyway) steakhouse in Buenos Aires, Argentina - https://flic.kr/p/ezE99U
  10. 10. Okay, fine… • Technically speaking, my vegan coworker does not like steak • Even if it is ‘good’ • But let’s not split hairs on this one… Copyright © 2014 Ping Identity Corp. All rights reserved. 10

  13. 13. The 64 Character Question • base64 – A means of encoding binary data in a printable ASCII string format – Each 6 bits -> 1 character • From a 64 character alphabet comprised of 62 alphanumeric characters and "+" and "/" • Also padding "=" – 3 bytes -> 4 characters • base64url – uses a URL safe alphabet rather than the nearly URL safe alphabet of regular base64 – "-" rather than "+" – "_" rather than "/" – Padding "=" is typically omitted • A remaining unreserved URI character: "." – This will prove important shortly Copyright © 2014 Ping Identity Corp. All rights reserved. 13 Example: 32 random bytes encoded base64: qOo+pY+LPDB7sA2nuMp4TzmCThieol/J+bAXqcB8pAU= base64url: qOo-pY-LPDB7sA2nuMp4TzmCThieol_J-bAXqcB8pAU URL Encoded: qOo%2BpY%2BLPDB7sA2nuMp4TzmCThieol%2FJ%2BbAXqcB8pAU%3D qOo-pY-LPDB7sA2nuMp4TzmCThieol_J-bAXqcB8pAU
  14. 14. A closer look at JOSE’s bits and pieces: JWS • JSON Web Signature (JWS) • A way of representing content secured with a digital signature or MAC – Using a JSON data structure and base64url encoding – Encoded segments are concatenated with a "." – Intended for space constrained environments such as HTTP Authorization headers and URI query parameters • Conceptually Simple: – <Header>.<Payload>.<Signature> Copyright © 2014 Ping Identity Corp. All rights reserved. 14
  15. 15. JOSE’s bits and pieces: The JWS Header • JWS Header is a bit of JSON that describes the digital signature or MAC operation applied to create the JWS Signature value • Reserved Header Parameters – "alg": Algorithm – HMAC, RSA, RSA-PSS and ECDSA – Unsigned/none (controversy!) – Extensible • "kid": Key ID • "jku": JWK Set URL • "jwk": JSON Web Key • "x5u": X.509 URL • "x5t": X.509 Thumbprint • "x5c": X.509 Certificate Chain • "typ": Type • "cty": Content Type Copyright © 2014 Ping Identity Corp. All rights reserved. 15 Header Example: "I signed this thing with RSA-SHA256 using key we known as ‘9er’ which you can find the corresponding public key for at https://www.example.com/jwks" {"alg":"RS256", "kid":"9er", "jku":"https://www.example.com/jwks"}
  16. 16. JOSE’s bits and pieces: JWS Algorithms Copyright © 2014 Ping Identity Corp. All rights reserved. 16 Digital Signature or Message Authentication Code Algorithm JWS "alg" Parameter Values HMAC using SHA2 HS256, HS384 and HS512 RSASSA-PKCS1-V1_5 Digital Signatures with with SHA2 RS256, RS384 and RS512 Elliptic Curve Digital Signatures (ECDSA) with SHA2 ES256, ES384 and ES512 RSASSA-PSS Digital Signatures with SHA2 PS256, PS384 and PS512 Unsigned Plaintext none
  17. 17. USA & Canada vs. a little context…
  18. 18. Jingoistic JWS Example Payload -> USA #1! base64url encoded payload -> VVNBICMxIQ Header (going to sign with ECDSA P-256 SHA-256 via "my-first-key") -> {"alg":"ES256","kid":"my-first-key"} base64url encoded header -> eyJhbGciOiJFUzI1NiIsImtpZCI6Im15LWZpcnN0LWtleSJ9 Secured Input -> eyJhbGciOiJFUzI1NiIsImtpZCI6Im15LWZpcnN0LWtleSJ9.VVNBICMxIQ base64url encoded signature over the Secured Input -> QJGB_sHj-w3yCBunJs2wxKgvZgG2Hq9PA- TDQEbNdTm2Wnj2sUSrBKZJAUREzF1FF25BbrgyohbKdGE1cB-hrA JWS Compact Serialization (line breaks after dots added for readability) -> eyJhbGciOiJFUzI1NiIsImtpZCI6Im15LWZpcnN0LWtleSJ9. VVNBICMxIQ. QJGB_sHj-w3yCBunJs2wxKgvZgG2Hq9PA- TDQEbNdTm2Wnj2sUSrBKZJAUREzF1FF25BbrgyohbKdGE1cB-hrA Which you can think of sort of like: {"alg":"ES256","kid":"my-first-key"}."USA #1!".<SIGNATURE>
  19. 19. JOSE’s bits and pieces: JWE • JSON Web Encryption • Similar in motivation and design to JWS but for encrypting content • A little more complicated – Headers • "alg": Algorithm (key wrap or agreement) • "enc": Encryption Method (Authenticated Encryption only) • "zip": Compression Algorithm – "DEF" for the DEFLATE Compressed Data Format from RFC 1951 is currently the only one • "kid”, “jku”, “jwk”, "x5u”, "x5t”, "x5c”, etc.. • Five Parts <Header>.<EncryptedKey>.<InitializationVector>.<Ciphertext>.<AuthenticationTag> Copyright © 2014 Ping Identity Corp. All rights reserved. 19
  20. 20. JOSE’s bits and pieces: JWE Content Encryption Algorithms ("enc") Copyright © 2014 Ping Identity Corp. All rights reserved. 20 Content Encryption Algorithm JWE "enc" Parameter Values Authenticated encryption with Advanced Encryption Standard (AES) in Galois/Counter Mode (GCM) A128GCM, A192GCM and A256GCM Authenticated encryption with an AES-CBC and HMAC-SHA2 composite A128CBC-HS256, A192CBC- HS384 and A256CBC-HS512
