引入的包

npm install sm-crypto

代碼加密解密

加密：

key ：代表著密鑰，必須是16 字節的十六進制密鑰
password ：加密前的密碼
sm4Password ：代表sm4加密后的密文

const sm4 = require('sm-crypto').sm4
const key = '0123456789abcdeffedcba9876543210' // 16 字節的十六進制密鑰
const sm4Password = sm4.encrypt(password, key) 

解密：

key ：代表著密鑰，必須是16 字節的十六進制密鑰
sm4Password：解密前的密文
password：解密后的密碼

const sm4 = require('sm-crypto').sm4
const key = '0123456789abcdeffedcba9876543210' // 16 字節的十六進制密鑰
const password= sm4.decrypt(sm4Password , key)
