一般 JWE JSON 序列化语法

JWE JSON 序列化将加密内容表示为 JSON 对象。此表示既未针对紧凑性进行优化，也未针对 URL 安全性进

此语法针对多个收件人进行了优化。

添加换行符以提高可读性

     {
      "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>"
     }
