一、首先 下载gm-crypto插件
npm install gm-crypto
//或者
yarn add gm-crypto
二、页面直接引入gm-crypto
import { SM4,SM3,SM2 } from 'gm-crypto';
SM2
const { publicKey, privateKey } = SM2.generateKeyPair()
const originalData = 'SM2 椭圆曲线公钥密码算法'
const encryptedData = SM2.encrypt(originalData, publicKey, {
inputEncoding: 'utf8',
outputEncoding: 'base64'
})
const decryptedData = SM2.decrypt(encryptedData, privateKey, {
inputEncoding: 'base64',
outputEncoding: 'utf8'
})
SM3
console.log(SM3.digest('abc'))
console.log(SM3.digest('YWJj', 'base64'))
console.log(SM3.digest('616263', 'hex', 'base64'))
SM4
const key = '0123456789abcdeffedcba9876543210' // Any string of 32 hexadecimal digits
const originalData = 'SM4 国标对称加密'
/**
* Block cipher modes:
* - ECB: electronic codebook
* - CBC: cipher block chaining
*/
let encryptedData, decryptedData
// ECB
encryptedData = SM4.encrypt(originalData, key, {
inputEncoding: 'utf8',
outputEncoding: 'base64'
})
decryptedData = SM4.decrypt(encryptedData, key, {
inputEncoding: 'base64',
outputEncoding: 'utf8'
})
// CBC
const iv = '0123456789abcdeffedcba9876543210' // Initialization vector(any string of 32 hexadecimal digits)实在不会写就直接用32个0代替
encryptedData = SM4.encrypt(originalData, key, {
iv,
mode: SM2.constants.CBC,
inputEncoding: 'utf8',
outputEncoding: 'hex'
})
decryptedData = SM4.decrypt(encryptedData, key, {
iv,
mode: SM2.constants.CBC,
inputEncoding: 'hex',
outputEncoding: 'utf8'
})
