About the difference between front-end AES encryption and background encryption.

the background is php. Use openssl to encrypt it with aes . The encryption result is consistent with the result of http://tool.chacuo.net/cryptaes.

The problem with

now is that the front end uses CryptoJS no matter what. Either the data encrypted in the background is inconsistent, or the CryptoJS encryption cannot be decrypted with CryptoJS .

what is the problem? if you have a better plan, please write it down as well. Too distressing.

php Code:

//
var aeskey = CryptoJS.enc.Utf8.parse("ABC123");
//
var aesiv = CryptoJS.enc.Utf8.parse(1111111111111111);

// 
function encrypt(data) {
    var srcs = CryptoJS.enc.Utf8.parse(data);
    var encrypted = CryptoJS.AES.encrypt(srcs, aeskey, {
        iv: aesiv,
        mode: CryptoJS.mode.CBC,
        padding: CryptoJS.pad.Pkcs7
    });
    //base64
    return encrypted.toString();
}

//
function decrypt(data) {
    // database64
    var decrypt = CryptoJS.AES.decrypt(data, aeskey, {
        iv: aesiv,
        mode: CryptoJS.mode.CBC,
        padding: CryptoJS.pad.Pkcs7
    });
    var decryptedStr = decrypt.toString();
    return decryptedStr;
}

// 
console.log(encrypt("1000001"));
