Question AES Encrypt In Javascript And Decrypt In C#

[joaocabaco]

Hello,

I'm having a hard time decrypting in C# data that was encrypted on client-side using CryptoJS.

Javascript Code:

[FONT=arial]<script src="[URL]http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/aes.js[/URL]"></script>[/FONT]
[FONT=arial]<script>[/FONT]
[FONT=arial]
[/FONT]
[FONT=arial]    var key = CryptoJS.enc.Utf8.parse('AMINHAKEYTEM32NYTES1234567891234');[/FONT]
[FONT=arial]    var iv = CryptoJS.enc.Utf8.parse('7061737323313233');[/FONT]
[FONT=arial]    var encrypted = CryptoJS.AES.encrypt(CryptoJS.enc.Utf8.parse("It works"), "Secret Passphrase", key, [/FONT]
[FONT=arial] { [/FONT]
[FONT=arial]     keySize: 128,[/FONT]
[FONT=arial]     iv: iv, [/FONT]
[FONT=arial]     mode: CryptoJS.mode.CBC,[/FONT]
[FONT=arial]     padding: CryptoJS.pad.Pkcs7 [/FONT]
[FONT=arial] }); [/FONT]
[FONT=arial]
