The concept behind encryption is quite simple - make the data unlegible for everyone else except those specified. This is done using cyrptography - the study of sending 'messages' in a secret form so that only those authorized to receive the 'message' be able to read it.
The easy part of encryption is applying a mathematical function to the plaintext and converting it to an ecrypted cipher. The harder part is to ensure that the people who are supposed to decipher this message can do so with ease, yet only those authorised are able to decipher it. We of-course also have to establish the legitimacy of the mathematical function used to make sure that it is sufficiently complex and mathmatically sound to give us a high degree of safety.
The essential concept underlying all automated and computer security application is cyptography. The two ways of going about this process are conventional (or symmetric) encryption and public key (or asymmetic) encryption.

I enjoyed reading the complete information and understood the complete process of encryption. Now I really wanted to know about the applications where this process is used.
