Study Material:

Symmetric Cryptography:

Symmetric key cryptography is also known as private key cryptography.

Symmetric key cryptography is a kind of cryptography where you need one key to encrypt & decrypt the message.

Encryption types: -

Stream ciphers-

Block ciphers-

Deffe-helman- this is a technique that is used to share the key between sender & receiver in the case of a symmetric key

Advantage-

One of the easiest & fastest cryptography techniques
Better performance
easier to implement
Asymmetric Cryptography:

Asymmetric cryptography is also known as public key cryptography.

Asymmetric key cryptography- We need two keys to encrypt & decrypt the message.

Public key- Encrypt the message

Private key- decrypting the message
