Encryption and Decryption.

• encryption is the process of encoding a message or information in such a way that only authorized parties can access it and those who are not authorized cannot. Encryption does not itself prevent interference but denies the intelligible content to a would-be interceptor.

• referred to as Plaintext, is encrypted using an encryption algorithm–a cipher–generating     cipher text that can be read only if decrypted.

• plaintext – information that can be directly read by humans or a machine (this article is an example of plaintext. Plaintext is a historic term pre-dating computers, when encryption was only used for hardcopy text, nowadays it is associated with many formats including music, movies and computer programs
• ciphertext – the encrypted data
• a cipher – the mathematics (or algorithm) responsible for turning plaintext into ciphertext and reverting ciphertext to plaintext (you might also see the word ‘code’ used – there is a technical difference between the two but it need not concern us now)
• encryption – the process of converting plaintext to ciphertext (occasionally you may see it called ‘encipherment’)
• decryption – the process of reverting ciphertext to plaintext (occasionally ‘decipherment’).
