CIPHER:
The idea of Cipher was conceptualized ever since even before the age of
the industrial revolution. The used of symbols and signs to send messages
across substantial distances was a major practiced in ancient times. The
idea of cipher has been at the epicentre." Since the introduction of the use
of Cipher, it has greatly impacted communication reliability due to its
ability to " make a secret" and "ensure the integrity" of the message. The
ciphers of yesterday (Caesar’s cipher) are far more different from that of
the current methodology driving modern ciphers operations. Modern
ciphers are more secure than classical ciphers and are designed to
withstand a wide range of attacks.
A ciphertext is encrypted text transformed from plaintext using an
encryption algorithm."
In cryptography (the art and science of transforming plaintext information
by means of suitable encryption techniques into ciphertext, which can
then be decrypted back into matching plaintext), a cipher is an algorithm
for performing encryption or decryption. Encryption and decryption are
series of well-defined steps that can be followed as procedure."
