what is cryptography?

Answer Posted / janu

Cryptogarphy is the art and science of Converting the
Confidential Messages from Readable format to Unreadable
Format. It is mainly used to sending and receiving an
messages between the Sender and Receiver. There are two
types of Cryptography.
1. Symmetric: Same Key(Public Key) is used for both
Encryption( Unreadable fromat) and Decryption(Readable
Format).
Both sender and Receiver Know this Public key.
2. ASymmetric: Different Key(Private Key) is used for both
Encryption( Unreadable fromat) and Decryption(Readable
Format.
sender Should send a msg to the Receiver with one
key.That's known by Sender alone. The Receiver should use
some Algorithms to find that key and Decrypted the msg.
This type of cryptography is more confidential than the
Symmetric cryptography.
