I am working on a form spam protection class which essentially replaces form field names with an encrypted value using mcrypt. The problem with this is that mcrypt encryption is not limited to only alphanumeric characters which would invalidate form fields. Given the code below, can you think of any reason why I'd be having problems de...
Does anybody has a WebLogic 8.1 two-way SSL full example? I am developing a small web application (1 HTML, 1 Servlet, 1 JSP) to send confidential data. The client could be a web browser. The server is WebLogic 8.1. The information should travel encrypted. Besides, the web application needs to authenticate the client, using more than a ...
I want my application to encrypt a user password, and at one time password will be decrypted to be sent to the server for authentication. A friend advise me to use HMAC. I wrote the following code in C#: System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding(); byte[] key = encoding.GetBytes("secret"); HMACSHA256 myhmacsha25...
I wrote this code in c# to encrypt a text with a key : using System; using System.Linq; using System.Collections.Generic; using System.Text; namespace ENCRYPT { class XORENC { private static int Bin2Dec(string num) { int _num = 0; for (int i = 0; i < num.Length; i++) { ...

This isn't meant to be secure by any means, so this...
