Cryptography is a method of protecting personal and official information from getting stolen. The main agenda of cryptography is to protect person communication.

Working of cryptography

1. The working of cryptography starts from a message which is converted into a form of a number.

2. After the conversion of the message into a number, the same numbered message is applied to a key which is known as ‘Encryption Key’. The same encryption key is used in an ‘Encryption Algorithm’.

3. When both the steps are applied in the encryption algorithm ‘Cipher text’ is formed. The same ciphertext is sent over various networks across the world.

4. After this, the receiver will use the ‘Description Key’ to get the actual message with the help of a ciphertext where it will act as a constraint of a description algorithm.

Cryptography is broadly classified into two main categories and those categories are mentioned below.

The first category of cryptography is ‘Symmetric Key Cryptography’ and the other one is ‘Asymmetric Key Cryptography’.

SYMMETRIC KEY CRYPTOGRAPHY

· Symmetric key cryptography is a type of cryptography that uses the same pattern of cryptography key for both encryptions of a plain text and description of a ciphertext.

· Here, the word ‘Key’ refers to the secrecy of more than two parties. Another name of symmetric key cryptography is ‘Secret Key Cryptography’.

· ‘Data Encryption Standards’ (DES) is one of the most famous symmetric key cryptography.

Symmetric key cryptography is further divided into ‘Transposition Cipher’ and ‘Substitution Cipher’.

TRANSPOSITION CIPHER

· It is a procedure of encryption where units of plaintext hold the position and those exact same positions are shifted with the accordance of a regular system.

· This way, the ciphertext initiates the arrangement of a plaintext.

· SUBSTITUTION CIPHER

· Substitution cipher is the second technique of symmetric key cryptography that replaces the character.

· So, it is basically a method where units of plaintext are replaced with ciphertext. Fixed systems say that units can have a single letter, pair of letters or a mixture of both.

ASYMMETRIC KEY CRYPTOGRAPHY

· Asymmetric Key Cryptography is a kind of cryptography that uses a pair of both public and private keys for doing encryption and description while communication.

· Asymmetric key cryptography is also called ‘Public Key Cryptography.

· It is more time consuming as compared to the symmetric key cryptography.

Likewise symmetric key cryptography, asymmetric key cryptography is also further categorized into two types; ‘Stream Cipher’ and ‘Block Cipher’.

STREAM CIPHER

· In order to produce the ciphertext, a stream cipher is used which is a procedure of encrypting the text.

· This is done by applying the cryptography key and algorithm to the binary digit in a data stream one by one.

BLOCK CIPHER

· Block cipher is a substitution of a stream cipher that encrypts the blocked text.

· It is also a type of method that uses algorithms for performing the given task and it is not like stream cipher where data streaming is done one by one.
