Cryptography is basically the process of hiding information in order to protect the sensitive information, data or message from unknown attacks for any reasons. Cryptography actually consists of two terms encryption and decryption. The process in which message is ciphered or encrypted is known as encryption and the process in which message is deciphered at recipients end is known as decryption. And this whole process is known as cryptography. Public keys and private keys are used in the process of cryptography. Cryptography can be seen as symmetric and asymmetric. In symmetric cryptography same key is used for both encryption and decryption while in asymmetric different keys are used for both encryption and decryption. Today Cryptography is used in various fields like ATM, e-banking, IT security, Maths etc.
prime numbers only be used as encryption keys as in encryption the numbers are coded inj the form of 0s and 1s ,i.e binary form.
Symmetric-key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.

Yes. Public Key encryption (or asymmetric encryption) requires a pair of keys; a public and a private key for exchanging data in a secure manner.
PKI must use asymmetric encryption because it is managing the keys in many cases. This implies the use of public and private key pairs, which is asymmetric.
The asymmetric key algorithms are used to create a mathematically related key pair: a secret private keyand a published public key.
Asymmetric encryption employs the use of public/private key pairs.
Symmetric encryption requires one key known by both parties. Asymmetric encryption uses two keys, one encryption key known publicly and one decryption key known only by the recipient.Or more simply put,YesA public and private key
