Simple insecure two-way data “obfuscation”?

Question

I\'m looking for very simple obfuscation (like encrypt and decrypt but not necessarily secure) functionality for some data. It\'s not mission critical. I need something to k

Answer 1

I wanted to post my solution since none of the above the solutions are as simple as mine. Let me know what you think:

 // This will return an encrypted string based on the unencrypted parameter
 public static string Encrypt(this string DecryptedValue)
 {
      HttpServerUtility.UrlTokenEncode(MachineKey.Protect(Encoding.UTF8.GetBytes(DecryptedValue.Trim())));
 }

 // This will return an unencrypted string based on the parameter
 public static string Decrypt(this string EncryptedValue)
 {
      Encoding.UTF8.GetString(MachineKey.Unprotect(HttpServerUtility.UrlTokenDecode(EncryptedValue)));
 }

Optional

This assumes that the MachineKey of the server used to encrypt the value is the same as the one used to decrypt the value. If desired, you can specify a static MachineKey in the Web.config so that your application can decrypt/encrypt data regardless of where it is run (e.g. development vs. production server). You can generate a static machine key following these instructions.
