This is the simplest kind of Cryptography that involves only one secret key to encrypt and decrypt information. It is also known as “Secret Key Cryptography”. Both Sender and receiver should know the key to be able to communicate securely. For Example: if Mahesh & Shalini wants to communicate using symmetric-key cryptography then both would have to devise key and use it for … Continue reading Symmetric Cryptography
Asymmetric cryptography, also known as public key cryptography, it uses two distinct, yet related keys. One key, the Public Key, is used for encryption and the other, the Private Key, is for decryption. Let say Mahesh wants to send an encrypted message to Shalini, Mahesh will look for Shalini Public key and use it for encrypt the message before sending it. Then Shalini Can decrypt … Continue reading Asymmetric Cryptography (Public Key Cryptography) – Part I
Cryptography categorized based on number of keys used for encryption and decryption; Below are list of cryptography catgories Secret Key Cryptography – It is also call symmetric encryption where for both encryption and decryption uses same key. This is mainly used for confidentiality. Public Key Cryptography – It is also called asymmetric encryption; this algorithm uses two key’s one for encryption and one for decryption. … Continue reading Basic of Cryptography (Type of Cryptography)- Part II
