Hiding Your eMail: 172 Ways to Keep Everything You Do Online, Secure

Realistically, anyone with access to data dumps from fiber-optic lines belonging to American telecom carriers will eventually be able to read your communications. However, it’s entirely possible to make it much more difficult for anyone to be able to pinpoint and decipher your movements online. When you can hide a message so that no one even suspects it exists, that is most secure, and if you can use a less traveled path of connection it also helps hide your tracks.Some people have figured out smart ways to stay invisible, but connected.

But if you’re like most of us and still using the public telecom system for browsing and e-mail, you’ll want to try out many of these 172 privacy tools to anonymize your web presence, encrypt your data, and erase your tracks.

  1. SSL – Secure Sockets Layer (SSL) protocol is a layer of software that operates between HTTP (internet protocol) and TCP (protocol for moving internet data from point to point), and it preserves security in internet transmissions by using RSA encryption.
