This is a GUI encryptor program written in Dev-C++. It uses no MFC. When it encrypts files, it encrypts them into stand-alone executable files that you can take with you wherever and execute (and enter the password you entered to began with) to decrypt.
It can encrypt binary (like executables, pictures, etc.) and ascii (text) files. When encrypting it also compresses the file using zlib (I used version 1.2.3 when compiling, which can be found at http://zlib.net or if you are using Dev-C++ you can just download it with the tools -> check for updates/packages option.). The zlib works great to add extra security to the encryption, and it also helps reduce the file size (it doesn’t work very well on reducing file size with binary files, but with text files it can reduce it by a lot). If you use this program, don’t loose the password you used to encrypt with, for it can not be retrieved.
The program takes a while to encrypt/decrypt larger files, for instance, it takes about 20 seconds to encrypt a 60 MB file, and the time just goes up from there.
I hope this program helps you, and have fun with it.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come
out every day, so no prevention program can catch 100% of them. For your own safety, please:
- Re-scan downloaded files using your personal virus checker before using it.
- NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
If you don't have a virus scanner, you can get one at many places on the net
including:McAfee.com
