JavaScript中的加密解密方法
Javascript加密解密方法主要有以下几种：1. 对称加密算法，如AES、DES等；2. 非对称加密算法，如RSA、ECC等；3. 哈希算法，如MD5、SHA-1等。其中，对称加密算法加解密速度快，但密钥管理复杂；非对称加密算法安全性高，但加解密速度慢；哈希算法主要用于数据完整性校验，不可逆。在实际应用中，可以根据需求选择合适的加密解密方法。同时，为了提高安全性，通常会结合使用多种加密技术，如先使用非对称加密算法进行密钥交换，再使用对称加密算法进行数据传输。

一些常见的built-in 函数加密
unescape
unescape() 函数可对通过 escape() 编码的字符串进行解码。
lete=escape("始識")console.log(e)//%u59CB%u8B58letu=unescape(e)console.log(u)//始識URL编码与解码
