What is Encryption?
Encryption is a process that converts a message or file so that it can be only be read by authenticate user. Encryption uses an algorithm to encrypt, data and then uses a key for the receiving user to decrypt, the information. The message contained in an encrypted message is referred to as plaintext. In its encrypted, unreadable form it is referred to as ciphertext.
Encryption requires the use of an encryption key: a set of mathematical values that both the sender and the recipient of an encrypted message know.
