In other words, it is the process of locking up information using cryptography (Cryptography is both the practice and the study of hiding information.) Definition: ‘ The Process of converting plain text into cipher text, something that appears to be random and meaningless ’ is called as the encryption. Process of converting cipher text back into original text is called as decryption . Terminology Original message is called as plain text/clear text. Encrypted message is called as cipher text/encrypted text. A Key which is a secret like a password which is used to encrypt and decrypt information. Ciphers are the specific algorithms which are used to encrypt and decrypt data. A cipher is series of well-defined steps that can be followed as a procedure to encryp...
