About Gpg4wingpg4win

 

Gpg4win (GNU Privacy Guard for Windows) is an encryption software to sign and encrypt files and emails.

What is Gpg4win?

Gpg4win enables users to securely transport emails and files with the help of encryption and digital signatures. Encryption protects the contents against an unwanted party reading it. Digital signatures make sure that it was not modified and comes from a specific sender.

Gpg4win supports both relevant cryptography standards, OpenPGP and S/MIME (X.509), and is the official GnuPG distribution for Windows. It is maintained by the developers of GnuPG. Gpg4win and the software included with Gpg4win are Free Software (Open Source; among other things free of charge for all commercial and non-commercial purposes).

Creation of Gpg4win was supported by the German Federal Office for Information Security (BSI).
