nodejs与javascript中的aes加密

Posted 2020-10-01 我叫阿良❤善良的良

 

// var CryptoJS = require("crypto-js");

// var key = CryptoJS.enc.Utf8.parse("8NONwyJtHesysWpM");

var crypto = require(\'crypto\');

var key = new Buffer(\'7y05R9qwKaIKgIHh4vAw19X1zuknR21Y\', \'binary\');

var iv = "";

var cryto_aes = module.exports = {};

 

//加密

cryto_aes.Encrypt = function(data){

 

　　iv = iv || "";

　　var clearEncoding = \'utf8\';

　　var cipherEncoding = \'base64\';

　　var cipherChunks = [];

　　var cipher = crypto.createCipheriv(\'aes-256-ecb\', key, iv);

　　cipher.setAutoPadding(true);

　　cipherChunks.push(cipher.update(data, clearEncoding, cipherEncoding));

　　cipherChunks.push(cipher.final(cipherEncoding));

　　return cipherChunks.join(\'\');

}

 

//解密

cryto_aes.Decrypt = function(data){

 

　　if (!data) {

　　　　return "";

　　}

　　iv = iv || "";

　　var clearEncoding = \'utf8\';

　　var cipherEncoding = \'base64\';

　　var cipherChunks = [];

　　var decipher = crypto.createDecipheriv(\'aes-256-ecb\', key, iv);

　　decipher.setAutoPadding(true);

　　cipherChunks.push(decipher.update(data, cipherEncoding, clearEncoding));

　　cipherChunks.push(decipher.final(clearEncoding));

　　return cipherChunks.join(\'\');

 

}

参照上述方法时注意 iv 和 key的设置  可能会报Invalid IV length 错  解决方法 就是 设置成我粘贴的代码中的格式。
