Dogs in warfare have a long history starting in ancient times. From war dogs trained in combat to their use as scouts, sentries and trackers, their uses have been varied and some continue to exist in modern military usage.
Encryption is the coding or scrambling of information so that it can only be decoded and read by someone who has the correct decoding key. Encryption is used in secure Web sites as well as other mediums of data transfer. If a third party were to intercept the information you sent via an encrypted connection, they would not be able to read it.
Encryption algorithms At the heart of every encrypted application is the algorithm, the math that scrambles and unscrambles data. In a nutshell, an encryption algorithm is a function which takes a string of data bytes and returns a new dataset containing unintelligible content. The same algorithm is used to decrypt data, which means encrypted data goes in from one side and the original data comes out the other.
