crypto-js aes 无法解密它加密的内容 [英] crypto-js aes can't decrypt what it encrypted

问题描述

您好，我正在尝试使用 crypto-js 解密加密的 aes 字符串，但似乎无法正常工作.

Hello I'm trying to decrypt a encrypted aes string with crypto-js but it seems like it doesn't work right.

我正在使用:

<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/aes.js"></script>
<script>
    var encrypted = CryptoJS.AES.encrypt("Message", "Secret Passphrase");

    var decrypted = CryptoJS.AES.decrypt(encrypted, "Secret Passphrase");
</script>

但我的结果是:

encrypted: U2FsdGVkX19whKq54yOQt3l1erbtEtn/M0qJjAH+E/E=
decrypted: 4d657373616765

我的期望是它返回消息".我错过了什么?

My expectation was the it returns back "Message". What am I missing?

推荐答案

所有CryptoJS..decrypt()函数的返回类型都是一个WordArray这是 CryptoJS 中二进制数据的原生表示.当您强制打印它时(自动调用 toString())，它包含的二进制数据将被十六进制编码.

The return type of all CryptoJS.<blockcipher>.decrypt() functions is a WordArray which is the native representation of binary data in CryptoJS. When you force it to be printed (automatically calling toString()), the binary data that it contains will be Hex encoded.

如果你想有不同的编码，那么你需要指定它.以下是一些示例:

If you want to have a different encoding, then you need to specify it. Here are some examples:

console.log(decrypted.toString()); // Hex encoded
console.log(decrypted.toString(CryptoJS.enc.Hex)); // Hex encoded
console.log(CryptoJS.enc.Hex.stringify(decrypted)); // Hex encoded

console.log(decrypted.toString(CryptoJS.enc.Utf8)); // UTF-8 encoded
console.log(CryptoJS.enc.Utf8.stringify(decrypted)); // UTF-8 encoded

console.log(decrypted.toString(CryptoJS.enc.Base64)); // Base64 encoded
console.log(CryptoJS.enc.Base64.stringify(decrypted)); // Base64 encoded
