There is a much larger demand for encryption nowadays for even such matters as your ordinary text mail. Protecting your data isn't a new thing and has existed for thousands of years. But today we use the computer in nearly every aspect of our life and our personal information is used together with the Web where each bit of information unencrypted could be viewed, recorded and used.
For many others, we understand exactly how important it's to encoded data but find the process incredibly cumbersome and difficult to get a grasp on. The Average person really does not comprehends "pgp -e messagefile her_user_id" or any other mysterious command line code to reestablish and/or decrypt the message. What is really needed for the typical individual is an simple to use encryption application that is based on the PGP standard. Terms Such as Symmetric and Asymmetric are a few of the names thrown about which you hear frequently connected with encryption. Symmetric Key algorithm could be regarded in more straightforward terms as one password algorithm (single key would be shared between the customer).
This single password can be used to encrypt the message in addition to decrypt the message also may be a tricky situation to get into the receiver. Asymmetric Key algorithm is the best way to go since it utilizes public and private key institution. Straightforward enough, your public key could be handed out to anybody as well as your private key stays private. Your public key will then disconnect the message in the sender and just you, together with all the private key can decrypt the message. The practice isn't too cumbersome if you are not looking at the internal workings of this code.
