crypto 模块

对内容进行加密

引入

import crypto from 'crypto'

const crypto = require('crypto')

md5

创建

const hash = crypto.createHash('md5')

写入加密内容

hash.update('hello world')
hash.update('more')

sha1

const hash = crypto.createHash('sha1')

hash.update('hello world')
hash.update('more')

hamac

可以指定密匙

const hash = crypto.createHmac('md5', 'mo')
// sha256

hash.update('hello world')
hash.update('more')

aes

加密

const encrypt = (key, iv, data) => {
    const dep = crypto.createCipheriv('aes-128-cbc', key, iv)
    return dep.update(data, 'binary', 'hex') + dep.final('hex')
}

解密

const decrypt = (key, iv, crypted) => {
    crypted = Buffer.from(crypted, 'hex').toString('binary')

    const dep = crypto.createDecipheriv('aes-128-cbc', key, iv)
    return dep.update(crypted, 'binary', 'utf8') + dep.final('utf8')
}
