我正在使用 PHP 加密一些参数
openssl("parameter", "AES-256-ECB", "client")
我希望在CryptoJS 中解密：
CryptoJS.AES.decrypt(parameter, "client", {mode: CryptoJS.mode.ECB}).toString(CryptoJS.enc.Utf8);
但它抛出一个空字符串。
有什么建议？
在 PHP openssl 中加密并在 javascript CryptoJS 中解密

CryptoJS：PHP openssl 加密 -> javascript 解密
PHP：
function CryptoJSAesEncrypt($passphrase, $plain_text){
$salt = openssl_random_pseudo_bytes(256);
$iv = openssl_random_pseudo_bytes(16);
//on PHP7 can use random_bytes() istead openssl_random_pseudo_bytes()
//or PHP5x see : https://github.com/paragonie/random_compat
$iterations = 999;
$key = hash_pbkdf2("sha512", $passphrase, $salt, $iterations, 64);
$encrypted_data = openssl_encrypt($plain_text, 'aes-256-cbc', hex2bin($key), OPENSSL_RAW_DATA, $iv);
$data = array("ciphertext" => base64_encode($encrypted_data), "iv" => bin2hex($iv), "salt" => bin2hex($salt));
return json_encode($data);
}
$string_json_fromPHP = CryptoJSAesEncrypt("your passphrase", "your plain text");
JS：
function CryptoJSAesDecrypt(passphrase,encrypted_json_string){
var obj_json = JSON.parse(encrypted_json_string);
var encrypted = obj_json.ciphertext;
var salt = CryptoJS.enc.Hex.parse(obj_json.salt);
var iv = CryptoJS.enc.Hex.parse(obj_json.iv);
var key = CryptoJS.PBKDF2(passphrase, salt, { hasher: CryptoJS.algo.SHA512, keySize: 64/8, iterations: 999});
var decrypted = CryptoJS.AES.decrypt(encrypted, key, { iv: iv});
return decrypted.toString(CryptoJS.enc.Utf8);
}
console.log(CryptoJSAesDecrypt('your passphrase','<?php echo $string_json_fromPHP?>'));
CryptoJS：javascript 加密 -> PHP openssl 解密
JS：
function CryptoJSAesEncrypt(passphrase, plain_text){
var salt = CryptoJS.lib.WordArray.random(256);
var iv = CryptoJS.lib.WordArray.random(16);
//for more random entropy can use : https://github.com/wwwtyro/cryptico/blob/master/random.js instead CryptoJS random() or another js PRNG
var key = CryptoJS.PBKDF2(passphrase, salt, { hasher: CryptoJS.algo.SHA512, keySize: 64/8, iterations: 999 });
var encrypted = CryptoJS.AES.encrypt(plain_text, key, {iv: iv});
var data = {
ciphertext : CryptoJS.enc.Base64.stringify(encrypted.ciphertext),
salt : CryptoJS.enc.Hex.stringify(salt),
iv : CryptoJS.enc.Hex.stringify(iv)
}
return JSON.stringify(data);
}
PHP：
function CryptoJSAesDecrypt($passphrase, $jsonString){
$jsondata = json_decode($jsonString, true);
try {
$salt = hex2bin($jsondata["salt"]);
$iv = hex2bin($jsondata["iv"]);
} catch(Exception $e) { return null; }
$ciphertext = base64_decode($jsondata["ciphertext"]);
$iterations = 999; //same as js encrypting
$key = hash_pbkdf2("sha512", $passphrase, $salt, $iterations, 64);
$decrypted= openssl_decrypt($ciphertext , 'aes-256-cbc', hex2bin($key), OPENSSL_RAW_DATA, $iv);
return $decrypted;
}
请使用这种方法它对我有用..谢谢
typescript代码（Anuglar 4+）：
encryptUsingAES256() {
let _key = CryptoJS.enc.Utf8.parse(your_token_here);
let _iv = CryptoJS.enc.Utf8.parse(your_token_here);
let encrypted = CryptoJS.AES.encrypt(
this.request, _key, {
keySize: 16,
iv: _iv,
mode: CryptoJS.mode.ECB,
padding: CryptoJS.pad.Pkcs7
});
this.encrypted = encrypted.toString();
console.log(this.encrypted)
}
decryptUsingAES256() {
let _key = CryptoJS.enc.Utf8.parse(your_token_here);
let _iv = CryptoJS.enc.Utf8.parse(your_token_here);
this.decrypted = CryptoJS.AES.decrypt(
this.encrypted, _key, {
keySize: 16,
iv: _iv,
mode: CryptoJS.mode.ECB,
padding: CryptoJS.pad.Pkcs7
}).toString(CryptoJS.enc.Utf8);
console.log(this.decrypted)
}
