CSimpleEncryption

CSimpleEncryption - A simple symmetric encryption algorithm
If you want to keep some of your application’s data private and just want a simple symmetric encryption algorithm, then this is the class you have been waiting for...

This class is based on a two step algorithm:
- The first step scrambles the input string by sorting all even and odd characters of the string. This makes it more difficult for ‘hackers’ to figure out the encryption algorithm.
- The second step simply adds a predefined value (in this case the length of the string and character position) to each character in the string.

The class has the following methods:

CString EncryptString(LPCTSTR lpszText);

where lpszText is the string you want to encrypt. The return value is the encrypted string.

CString DecryptString(LPCTSTR lpszText);

where lpszText is the string you want to decrypt. The return value is the decrypted (original) string..

For a more complex (and better) type of encryption, check out my CEncryption class which uses the Microsoft CryptoAPI.
