Introduction
Cipher is the art and science of converting information from one form to another so that it can be kept secret from unauthorized parties. It is a powerful tool that has been used for centuries to protect sensitive information, ranging from military secrets to personal communications. In today's digital age, cipher is more important than ever, as we rely on it to protect our online privacy and security.
Methods of Cipher
There are many different methods of cipher, each with its own strengths and weaknesses. Some of the most common methods include:
-
Substitution ciphers replace each letter in the plaintext with another letter or symbol.
-
Transposition ciphers rearrange the order of the letters in the plaintext.
-
Block ciphers encrypt blocks of plaintext at a time, using a complex mathematical algorithm.
-
Stream ciphers encrypt plaintext one bit at a time, using a pseudorandom number generator.
