Crypt allows you to encode your files in order to be absolutely unreadable. The only thing you must do is right click on the file to encode, select Crypt, write the encryption password and click Apply. That's all!
Crypt uses a powerful symmetric cryptographic algorithm. This means that your files will be safe against unwanted reading attempts and they can only be decoded using the password you used to encrypt them.
Crypt is completely freeware. It has GPL licenses (without limitations of use); just install it and enjoy :D. If you like the software and you want to thank the work, you can make a donation; even the smallest help will be hugely appreciated.
Crypt is available for Windows systems, from Vista to lastest versions (and XP if you have .NET framework installed - if you got 0xc0000135 error you don't have .NET installed; download it from here). It also supports both 32 bits and 64 bits versions.
Crypt is consistent with the language of your system automatically. Currently it includes English and Spanish. If you are interested in translating it into your language, feel free to contact the author!
If you have sensitive data that you do not want to be accessible without your permission, Crypt is the software you need!
