Cipher: When encryption and decryption are performed in a particular type then it is called as cipher algorithm . There are different types of cipher and they are: Substitution cipher Caesar cipher Transposition cipher The cipher algorithm such as transposition and substitution cipher does not greatly challenge with the modern computer systems much, It is because the sender and receiver share their cipher key whenever the information is transmitted. The key that is shared creates a problem between the two parties and which may lead to risk in the future. To resolve the above problem, public key cryptography is utilized where in each user will be having a pair of keys. The messages are encrypted using one type of key called public key and decryption is made using another key called private key.
