In order to maintain your complete privacy you do have the option to encrypt the files you send to us. By sending us a self-decrypting file you ensure that we, or any other undesired third party, are unable to view your files. As well, by answering a test question of your choosing, the desired end party is able to decrypt your files effortlessly and without installing any software onto their computer. Self-decrypting files can be made with any number of programs: We currently recommend Zero Footprint Crypt, an excellent freeware choice.
