几种常见的加密方式

线性散列加密算法

常见算法：MD5、SHA-1、SHA-256、HMAC

主要特点：不可逆，一旦加密就不能反向解密得到密码原文。

适用场景：用于存储用户私有信息，如交易密码等不可解密的信息。

非对称加密算法

常见算法：RSA、DSA、ECC

主要特点：加密和解密采用不同的密钥（公钥和私钥）。

优点：公钥加密，私钥解密；相比于对称加密，安全性更高。

缺点：加密和解密花费时间长、速度慢，只适合对少量数据进行加密。

适用场景：常用于传递用户敏感信息，但是需要进行解密验证的信息。

对称加密算法

常见算法：AES、DES、3DES

主要特点：加密和解密采用相同的密钥（公用一个密钥）

优点：加解密过程中计算量小、加密速度快、加密效率高。

缺点：密钥的传递和保存是个问题，容易泄露，没有非对称加密安全。

适用场景：一般用于保存用户手机号、身份证等敏感但能解密的信息。

RSA加密使用
