If you're using a Macintosh to download files or use a Windows computer, you can use GPG4WIN to help protect your security. GPG is a software package that will not let any of the unauthorized parties get your private information, keys, or passwords. It uses the free RSA secret sharing method and then keeps a backup copy of these keys in a safe place. When you need to download something from the Internet, you simply download it with GPG. It will search for the key in a secure file, then give you the option to use a password, private key, or fingerprint to decrypt your file. Although this software is free, there are a few things you should be aware of before you download it. You'll want to make sure the download is secure, and you want to make sure that you're downloading the right version. This is very important since not all computers will have the same encryption techniques and encryption keys. The problem with many downloads is that the company does not give the exact keys or encryption methods but will just give you a "bad"old" version. When you find a download that is secure, that has the correct keys, and has the latest version, the best choice for you is to use this. After all, if you have a virus on your computer, that will get into the program and make it do more harm than good. Make sure you're downloading the version that is right for your computer, and that it's not already infected. If you like this software, you can try asking for a trial download. Most software providers will send you a trial, which can be installed with the rest of your system. Once the trial is installed, you can use it as often as you like. If you want to use the full version, you can pay extra for it. This is a pretty cost effective solution to your security issues when you need to download something.
