WS_FTP Professional (v. 12.4) - Site License - 1 additional license

WS FTP Professional features OpenPGP (Pretty Good Privacy) that gives you the ability to create an additional level of privacy. It does this by encrypting each individual file with key technology so that only the intended person, who had previously provided their public key, can read it. When encrypted, the message looks like a meaningless jumble of random characters.
