【Class: EncapsulatedKey】

用于消息加密的临时对称秘密密钥（表示为 <CryptoKey>）以及使用该共享密钥加密的密文（可以与消息一起传送给消息接收者）。接收者使用他们的私钥来确定共享密钥，从而能够解密消息。

【A temporary symmetric secret key (represented as <CryptoKey>) for message encryption and the ciphertext (that can be transmitted to the message recipient along with the message) encrypted by this shared key.
