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.
Definition of:encryption algorithm. A formula used to turn ordinary data, or plaintext, into a secret code known as ciphertext.. Each algorithm uses a string of bits known as a key to perform the calculations. The larger the key (the more bits), the greater the number of potential patterns can be created, thus making it harder to break the code and descramble the contents.
