Webcryptographic primitives，即为密码学原语，也就是基本的密码概念，如加密、签名、Hash等算法。但是直接使用密码学原语容易出错，在实际应用中无法保证安全性。

WebA basic construction used within many cryptographic systems is envelope encryption. Envelope encryption uses two or more cryptographic keys to secure a message. Typically, one key is derived from a longer-term static key k, and another key is a per-message key, msgKey, which is generated to encrypt the message.
