jwt Serializations General JWE JSON Serialization Syntax


Example

The JWE JSON Serialization represents encrypted content as a JSON object. This representation is neither optimized for compactness nor URL safe.

This syntax is optimized for more than one recipient.

Line breaks added for readability

     {
      "protected":"<integrity-protected shared header contents>",
      "unprotected":<non-integrity-protected shared header contents>,
      "recipients":[
       {"header":<per-recipient unprotected header 1 contents>,
        "encrypted_key":"<encrypted key 1 contents>"},
       ...
       {"header":<per-recipient unprotected header N contents>,
        "encrypted_key":"<encrypted key N contents>"}],
      "aad":"<additional authenticated data contents>",
      "iv":"<initialization vector contents>",
      "ciphertext":"<ciphertext contents>",
      "tag":"<authentication tag contents>"
     }
