Gpg4win is a free program that allows the use of advanced cryptographic solutions in Windows. By using the encryption solutions provided by GNU Privacy Guard (GnuPG), you can use the technology which has been, until recently, restricted to U.S. government agencies.
Gpg4win uses a free license version of the PGP encryption system based on a pair of keys. Anyone who wants to make use of the encryption must generate the two strings: a private key and a public key. Your private key must remain known only to you and it must be secured by a password. The public key should be shared with other parties.
If you want to send an encrypted message, encrypts the public key of the recipient - you can find it on the appropriate server called the key server. Such a message can decrypt only the holder of the matching private key.
Your public key can be used to sign your message. Gpg4win then calculates your message short and encrypts your private key. The recipient knowing your public key can read or abbreviation is correct. Because the private key, only you can know, it is certain that you are the author and the message has not been altered.
Gpg4win is not very easy to use, although still better than the default command line offered by GnuGP. Encrypting email messages with this program is an excellent choice.
At the end of the day, Gpg4win really does provide a way to effectively encrypt data and messages, though not easy to use at first.Gpg4win features and highlights:
