AxCrypt is free and open source file encryption software for Windows. This program allows you to compress, encrypt, decrypt, store, send and work with individual files.

AxCrypt encrypts files up to 4GB size and you can easily send to other users via e-mail(the smaller ones of course) or any other means,making this application a great complement for programs like DropBox, skylive and all those File Sharing Services. It also offers an amazing feature, the Self-decrypting files, dispensing the need to install AxCrypt to decrypt.

Axcrypt is really easy to install and easy to use, there is no need to make any kind of configuration and that is why there´s no user interface.
