CBOR Web Token

Overview#

CBOR Web Token (CWT RFC 8392) is a compact means of representing claims to be transferred between two parties.

The claims in a CBOR Web Token are encoded in the Concise Binary Object Representation (CBOR) and CBOR Object Signing and Encryption (COSE) is used for added Application Layer security protection.

A claim is a piece of information asserted about a subject and is represented as a name/value pair consisting of a claim name and a claim value. CWT is derived from JSON Web Token (JWT) but uses CBOR rather than JSON.

CWT is a profile of the JSON Web Token (JWT) that is optimized for constrained devices. The claims in a CWT are encoded in the Concise Binary Object Representation (CBOR) and CBOR Object Signing and Encryption (COSE) is used for added application layer security protection.

The suggested pronunciation of CWT is the same as the English word "cot".
