我有一个已编码的字符串，需要对其进行解密。我使用过 Crypto JS，经过一定的研究，我可以达到以下解决方案。
data = "+JdTb5BOloxaBHQlTw6NPLNV9lZix1OwhR3HF3IRtu2pdg/TLkrTw6Xu4JpKFlxE+zgOZavj0UynSZ+ojxmDXRbUlfyOc4YAncJVMXr28/AtfxZkNQoHbPIo7WxcSdidNE2k+DHZFcNNKOzYnvL1oDN4ezecs8Vo7K6vC5ZFLPUylXsi5sPsGye+TBbauPX+/wXa3hWUJVMNk6HUghW7l4N5Ei7HnrxLkFSFnz+9YUKYbFMEgV6wd9debHrpyytVhA3x2+Eyn5KnQ7iNJKQsNw==";
key = "062ec23950a55b9f8b21b0f9d45ca853";
// Decode the base64 data so we can separate iv and crypt text.
var rawData = atob(data);
var iv = rawData.substring(0,32);
var crypttext = rawData.substring(32);
// Decrypt...
var plaintextArray = CryptoJS.AES.decrypt(
{ ciphertext: CryptoJS.enc.Latin1.parse(crypttext) },
CryptoJS.enc.Hex.parse(key),
{ iv: CryptoJS.enc.Latin1.parse(iv) }
);
var test = CryptoJS.enc.Latin1.stringify(plaintextArray);
console.log(test.toString())<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/aes.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/crypto-js.min.js"></script>上面的输出是
8«ÊWÒϬR¶jÛWY#ESPONSE_TEXT>
<RESULT>OK</RESULT>
<RESULT_CODE>-1</RESULT_CODE>
<TERMINATION_STATUS>SUCCESS</TERMINATION_STATUS>
<COUNTER>2</COUNTER>
</RESPONSE>
代替
<RESPONSE_TEXT>
<RESULT>OK</RESULT>
<RESULT_CODE>-1</RESULT_CODE>
<TERMINATION_STATUS>SUCCESS</TERMINATION_STATUS>
<COUNTER>2</COUNTER>
</RESPONSE>
我无法找到为什么8«ÊWÒϬR¶jÛWY会出现结果。请帮助找到丢失的线程。
使用 - CryptoJS.lib.WordArray.random(128/8) 生成 iv
