Full Title

Javascript Object Signing and Encryption (jose)

Context

In OAuth 2.0 and other specs from the Open ID Foundation, there was a need for a small packed of identity information that could be coded and include in a HTTP header.

Problems

  • The existing specs at the time the JWT was created were XML and SAML which were very wording and not amenable to coding in an HTTP header.

Solutions

  • RFC 7165 Use Cases and Requirements for JSON Object Signing and Encryption (JOSE)
  • The IETF Working Group on Javascript Object Signing and Encryption (jose) issued a final report.
    JavaScript Object Notation (JSON) is a text format for the serialization of structured data described in RFC 4627. The JSON format is often used for serializing and transmitting structured data over a network connection. With the increased usage of JSON in protocols in the IETF and elsewhere, there is now a desire to offer security services, which use encryption, digital signatures, message authentication codes (MACs) algorithms, that carry their data in JSON format.
  • Justin Richer has some suggestions.[1]
