• 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
• 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.

I didn’t…
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-

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
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…

{"JSON" : "a lightweight & human-readable data-interchange format"}!
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 "+" and "_" rather than "/"
– Padding "=" is typically omitted
• A remaining unreserved URI character: "."
– This will prove important shortly

Example: 32 random bytes encoded
base64: qOo+pY+LPDB7sA2nuMp4TzmCThieol/J+bAXqcB8pAU=base64url: qOo-pY-LPDB7sA2nuMp4TzmCThieol_J-bAXqcB8pAUURL Encoded:qOo%2BpY%2BLPDB7sA2nuMp4TzmCThieol%2FJ%2BbAXqcB8pAU%3DqOo-pY-LPDB7sA2nuMp4TzmCThieol_J-bAXqcB8pAU
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
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"}
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!
USA!&!
Canada
vs.
a little context…
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>
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>

JWT!
• JSON Web Token • Suggested pronunciation: "jot" • Compact URL-safe means of representing claims to be
transferred between two parties • JWS and/or JWE with JSON claims as the payload • JWT Claim
– A piece of information asserted about a subject (or the JWT itself)
– Represented name/value pairs, consisting of a Claim Name and a Claim Value (which can be any JSON object)
Copyright © 2014 Ping Identity Corp. All rights reserved. 24
• "iss": Issuer – Who issued it
• "sub": Subject – Who’s it about
• "aud": Audience – Who’s it for
• "exp": Expiration Time – When it expires
• "nbf": Not Before – When it starts being value
• "iat": Issued At – When it was issued
• "jti": JWT ID – A unique identifier for it
Copyright © 2014 Ping Identity Corp. All rights reserved. 25

…it’s how you use it!
• Simpler = Better • Web safe encoding w/ no canonicalization
(Because canonicalization is a four letter word*)
• Improved Interoperability & (hopefully) More Secure
• Eliminates entire classes of attacks – XSLT Transform DOS, Remote Code Execution, and Bypass
– C14N Hash Collision w/ & w/out comments
– Entity Expansion Attacks
– XPath Transform DOS and Bypass
– External Reference DOS
– Signature Wrapping Attacks

Brad Hill, pictured here speaking at CIS in 2011, is wicked smaht and published some of these attacks
* especially when you spell it c14n
JSON Web Key (JWK)!
Copyright © 2014 Ping Identity Corp. All rights reserved. 29
• JSON data structure representing cryptographic key(s) – Public/private keys: RSA & Elliptic Curve
– Symmetric keys (octet sequence)
• Can can be – included in a JWS/JWE/JWT header
– published at an HTTPS endpoint and referenced
– used in place of self signed certificates
– saved in a file
– sent in an email
– and more
JWK & JWT Working Together!

Simple Is As Simple Does!
• The relative simplicity of JW[STEAK] implies a simple programming interface!
• Numerous implementations already exist for a wide variety of languages/platforms !
• Going to make you take quick look at one of them… !

Introducing jose4j!
• Open source Java implementation of the JOSE specification suite – https://bitbucket.org/b_c/jose4j
• Relies solely on the JCA APIs for cryptography • 100% Algorithm Support
• Production ready – Used throughout Ping Identity’s products
• Reference[able] implementation – Fact checked the JOSE cookbook: http://tools.ietf.org/html/draft-ietf-jose-cookbook-02#appendix-A
• Completely free of NSA backdoors – (but I’m open to "sponsorship" opportunities)
