前端加解密，ECB，CBC

本文主要是介绍前端加解密，ECB，CBC，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

前端数据加密解密

使用crypto-js

加解密代码如下

    encryptECB(word, EK) {if (word === null) {return word;}let key = CryptoJS.enc.Utf8.parse(EK);let srcs = CryptoJS.enc.Utf8.parse(word);let encrypted = CryptoJS.AES.encrypt(srcs, key, {mode: CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});return encrypted.ciphertext.toString().toUpperCase();},/** ECB解密 */decryptECB(word, EK) {if (word === null) {return word;}let key = CryptoJS.enc.Utf8.parse(EK);let encryptedHexStr = CryptoJS.enc.Hex.parse(word);let srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr);let decrypt = CryptoJS.AES.decrypt(srcs, key, {mode: CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});let decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);return decryptedStr.toString();},/** CBC加密 */encryptCBC(word, EK) {if (word === null) {return word;}let iv = CryptoJS.enc.Utf8.parse(EK);let key = CryptoJS.enc.Utf8.parse(EK);let srcs = CryptoJS.enc.Utf8.parse(word);let encrypted = CryptoJS.AES.encrypt(srcs, key, {iv: iv,mode: CryptoJS.mode.CBC,padding: CryptoJS.pad.ZeroPadding});return encrypted.toString();},/** CBC解密 */decryptCBC(word, EK) {if (word === null) {return word;}let iv = CryptoJS.enc.Utf8.parse(EK);let key = CryptoJS.enc.Utf8.parse(EK);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.ZeroPadding});let decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);return decryptedStr.toString();}
