代码加密解密
加密:
key :代表着密钥,必须是16 字节的十六进制密钥
password :加密前的密码
sm4Password :代表sm4加密后的密文
const sm4 = require('sm-crypto').sm4
const key = '0123456789abcdeffedcba9876543210' // 16 字节的十六进制密钥
const sm4Password = sm4.encrypt(password, key)
解密:

sm4Password:解密前的密文
password:解密后的密码
const sm4 = require('sm-crypto').sm4
const key = '0123456789abcdeffedcba9876543210' // 16 字节的十六进制密钥
const password= sm4.decrypt(sm4Password , key)
