密码不转换为纯文本，没有被提醒 [英] Ciphertext is not converting to plain text and is not being alerted
问题描述
我无法解密密文。我必须测试我的解密是否正常工作。所以，我创建了一个简单的html文件，它采用密文，而不是将其转换为纯文本。
I am not able to decrypt a ciphertext. I have to test that my decryption is working properly or not. So, I created a simple html file which take cipher text and than convert it into plain text.
我刚刚在这里硬编码价值，而不是将密文转换为纯文本。
I just here hardcoding the value and than converting ciphertext into plain text.
当我尝试它是根本不工作我不明白是什么问题。
When I tried it it was not working at all. I don't understand what is the issue.
这是我的代码
<!DOCTYPE html>
<html>
<head>
<script src="tripledes.js"></script>
<script src="mode-ecb.js"></script>
<style type="text/css">
<script type="text/javascript">
function decryptByDES(aHJHDJSHJhjsak=, highishjdhsjhjs) {
var keyHex = CryptoJS.enc.Utf8.parse(highishjdhsjhjs);
var decrypted = CryptoJS.DES.decrypt({
ciphertext: CryptoJS.enc.Base64.parse(aHJHDJSHJhjsak=)
}, keyHex, {
mode: CryptoJS.mode.ECB,
padding: CryptoJS.pad.Pkcs7
});
return decrypted.toString(CryptoJS.enc.Utf8);
alert ( decrypted);
}
</script>
</head>
<body>
<div class="maindiv">
<div>
<label for="name">Message:</label>
<input type="text" id="msg" name="msg" />
</div>
<div>
<label for="mail">Key:</label>
<input type="text" id="key" name="key" />
</div>
<div class="button">
<button onclick="decryptByDES()">View</button>
</div>
</div>
</body>
</html>
，而我的mode-ecb.js文件是
and my mode-ecb.js file is

*/
/**
* Electronic Codebook block mode.
*/
CryptoJS.mode.ECB = (function () {
var ECB = CryptoJS.lib.BlockCipherMode.extend();
ECB.Encryptor = ECB.extend({
processBlock: function (words, offset) {
this._cipher.encryptBlock(words, offset);
}
});
ECB.Decryptor = ECB.extend({
processBlock: function (words, offset) {
this._cipher.decryptBlock(words, offset);
}
});
return ECB;
}());
我需要在警报中显示我的解密文本。但没有任何事情发生。
I need to show my decrypted text in an alert. But nothing is happening.
推荐答案
我不熟悉CryptoJS，但...看起来你需要在 return decryptpted.toString（CryptoJS.enc.Utf8）; 行，因为该函数返回时不会调用警报。
I'm not familiar with CryptoJS, but... It looks like you need to move the alert before the return decrypted.toString(CryptoJS.enc.Utf8); line, as the alert won't get called once the function returns.
另外，最好的做法是将密钥和密文变量字符串，然后从传递这些变量的按钮中调用它（尽管你可能想要将你的密钥存储在javascript中，只传入cipherTextString） 。
Also, it would be better practice to make your key and cipher text variable strings, then call it from the button passing in those variables (although you may want to store your key in the javascript, and only pass in the cipherTextString).
<script type="text/javascript">
function decryptByDES(cipherTextString, keyString) {
var keyHex = CryptoJS.enc.Utf8.parse(keyString);
var decrypted = CryptoJS.DES.decrypt({
ciphertext: CryptoJS.enc.Base64.parse(cipherTextString)
}, keyHex, {
mode: CryptoJS.mode.ECB,
padding: CryptoJS.pad.Pkcs7
});
var decryptedStringified = decrypted.toString(CryptoJS.enc.Utf8);
alert(decryptedStringified);
return decryptedStringified;
}
</script>
然后从您的按钮中调用它，传入正确的变量：
And then call it from your button, passing in the correct variables:
<button onclick="decryptByDES('aHJHDJSHJhjsak=', 'highishjdhsjhjs');">View</button>
