CryptoJS文件加密与解密

import React, { Component } from ‘react‘;

class Encryption extends Component {
    constructor(){

        this.state={
            value2:‘qqqqqqqqqqqq‘,
            encryptioned:‘‘,

    render() {

            <div>
                <p><input value={this.state.value2} type="text"/></p>
                <Button type="primary" onClick={this.encryption.bind(this)}>请输入要加密的内容</Button>
                <br/>
                <h2>
                    加密之后的内容：<span>{this.state.encryptioned}</span>
                </h2>
                <Button type="primary" onClick={this.Decrypt.bind(this)}>对加密文件进行解密</Button>
                <br/>
                <h2>
                    解密之后的内容：<span>{this.state.Decrypted}</span>
                </h2>
            </div>
        )
    }
}
export default Encryption;
这里的密钥是由十六位十六进制数作为密钥组成

 //十六位十六进制数作为密钥偏移量

const CryptoJS = require(‘crypto-js‘); //引用AES源码js const key = CryptoJS.enc.Utf8.parse("1234123412ABCDEF"); //十六位十六进制数作为密钥 const iv = CryptoJS.enc.Utf8.parse(‘ABCDEF1234123412‘); //十六位十六进制数作为密钥偏移量 //解密方法 function Decrypt(word) { let encryptedHexStr = CryptoJS.enc.Hex.parse(word); let srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr); let decrypt = CryptoJS.AES.decrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }); let decryptedStr = decrypt.toString(CryptoJS.enc.Utf8); return decryptedStr.toString(); } //加密方法 function Encrypt(word) { let srcs = CryptoJS.enc.Utf8.parse(word); let encrypted = CryptoJS.AES.encrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }); return encrypted.ciphertext.toString().toUpperCase(); } export default { Decrypt , Encrypt }
