我需要從客戶端(JavaScript)當然字符串進行加密,並從服務器端(Java)進行解密,所以我找到了CryptoJS,並使用相同的參數/配置mi Java代碼但輸出總是不同的,你有什麼想法或發生了什麼?不同的輸出加密CryptoJS和Java代碼
我使用CBC與NoPadding
CryptoJS

<script>
function padString(source) {
var paddingChar = ' ';
var size = 16;
var x = source.length % size;
var padLength = size - x;
for (var i = 0; i < padLength; i++) source += paddingChar;
return source;
}
var key = CryptoJS.enc.Hex.parse('abcdef');
var iv = CryptoJS.enc.Hex.parse('fedcba');
var message = "soldier";
var padMsg = padString(message);
var encrypted = CryptoJS.AES.encrypt(padMsg, key, { iv: iv, padding: CryptoJS.pad.NoPadding, mode: CryptoJS.mode.CBC});
console.log("Encrypted: "+encrypted);
console.log("Encrypted text: "+encrypted.ciphertext);
</script>
Java代碼的

原始字符串:從CryptoJS
soldier
輸出:從Java代碼
Encrypted: VNzZNKJTqfRbM7zO/M4cDQ==
Encrypted Hex: 54dcd934a253a9f45b33bccefcce1c0d
輸出:
Encrypted: j6dSmg2lfjY2RpN91GNgNw==
Encrypted Hex: 6a3664536d67326c666a593252704e3931474e674e773d3d
加密基於64位字符串具有相同的長度,而不是十六進制。 如果我把CryptoJS的輸出結果放在Java代碼中,解密是不正確的。
問候,
工作正常,非常感謝:) – SoldierCorp
