js端加密 java后端解密

本加密方法是AES可逆加密。适用于前端加密密码，后端解密密码。保证数据安全等方案。

要引入的js库文件：https://download.csdn.net/download/qq_38973042/10430478

//js前端获取要加密字段进行加密

var loginPwd = $("#loginpwd_id").val();

loginPwd = encrypt(loginPwd);

//加密方法

function encrypt(word){
    var key = CryptoJS.enc.Utf8.parse("abcdefghabcdefgh");   //定义加密的密钥  密钥前端和后端必须一致  且为16位
    var srcs = CryptoJS.enc.Utf8.parse(word);
    var encrypted = CryptoJS.AES.encrypt(srcs, key, {mode:CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});
    return encrypted.toString();
}

//解密方法

function decrypt(word){
    var key = CryptoJS.enc.Utf8.parse("abcdefghabcdefgh");   //定义加密的密钥  密钥前后一致 为16位
    var decrypt = CryptoJS.AES.decrypt(word, key, {mode:CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});
    return CryptoJS.enc.Utf8.stringify(decrypt).toString();
}
