Gpg4win

Gpg4win is one of the best, if not the best free program for Windows (it is also open source and can also be used for commercial purposes) be able to encrypt their email. And the program that most closely recalls Pgp Pro has long become a fee.

To protect your emails using the classic system of the key pair, the public key (for distribution to those who will read our emails) and private key are created through the program and verify digital signatures.

It can use Gpg4win in two ways: either using the programs in Gpg4win, making it able to work with any email client (in this case it will do some cutting and pasting text from encrypted email client to WinPT, a Gpg4win application contained in the package) or via plugin (for example there is a plugin for Outlook), in which case we will do everything within the mail client itself.

Using Gpg4win is not difficult, however, if you are not familiar in this field (creation/use of public and private key, etc..), It is essential to read the program guide.
