What is classical cryptography?

Classical Cryptography has two types of techniques: In the symmetric cryptography a single key is used for encrypting and decryption the data. This encryption key is private key. This is the limitation of this encryption technique that this private key must be distributed only among the authorized sender and receiver.

What is the difference between public key and private key cryptography?

It is faster than the public key cryptography. In Public key, two keys are used one key is used for encryption and another key is used for decryption. One key (public key) is used for encrypt the plain text to convert it into cipher text and another key (private key) is used by receiver to decrypt the cipher text to read the message.

Asymmetric Cryptography: In the asymmetric cryptography a pair of key, i.e., public key and private key is used for... While ...

Is symmetric key encryption better than public key encryption?

So, symmetric key encryption may be better for encrypting large amounts of data. Furthermore, public key encryption algorithms must use a comparatively stronger key than symmetric key encryption to achieve the same strength (for the simple reason that one key is made public in public key cryptography).
