I am seeking a freeware, open-source, or fairly cheap PGP Command Line app which can do PGP file encryption.

It should be a Windows solution, and should be able to be called at the command-line, passing parameters, or using a Batch file.

It should also support all the latest versions of windows and windows servers OS.

Please, no GUI interfaces. I seek just a command-line tool. The smaller the package (less distributable) the better.

Thanks for any help you may provide

There's a Windows port of GNU Privacy Guard (gpg) at

Since you want the smallest thing that does the job: the "light" release for version 1.0.9 is only 4MB. See

Wouldn't that be GPG?

Tried downloading it. One link i ended up getting nothing but C code. The other link was a huge Windows GUI package. Any ideas, exactly what i need to download to get a command-line binary to do file exncryption? Very hard deciphering the downloads – Johnny Holmes Apr 23 '12 at 22:53
@JohnnyHolmes The page I linked to above says "Project Gpg4win provides a Windows version of GnuPG. It is nicely integrated into an installer and features several frontends as well as English and German manuals." That page has a "Download" button that takes you to a list of downloads including Vanilla installer. – RedGrittyBrick Apr 24 '12 at 9:18
