IETF logoThe -11 drafts of the JSON Object Signing and Encryption (JOSE) specifications have been released that incorporate the changes agreed to at the interim working group meeting last month. Most of the changes were to the JWS and JWE JSON Serialization representations, enabling more flexible treatment of header parameter values. Other changes included removing the Encrypted Key value from the JWE integrity calculation, saying more about key identification, adding key identification parameters to some of the examples, clarifying the use of “kid” values in JWK Sets, enabling X.509 key representations in JWKs, recommending protecting JWKs containing non-public information by encrypting them with JWE, adding “alg” values for RSASSA-PSS, registering additional MIME types, and a number of clarifications. A corresponding -08 JSON Web Token (JWT) spec was also released that updated the encrypted JWT example value to track the JWE change. Hopefully this will be the last breaking change to the encryption calculations.
