Nearly all asymmetric encryption algorithms - and all the common ones, use 2 keys. Typically one key is held secret by the owner and is known as the "private key" while the other is published or distributed to the world and is known as the public key. Each key allows for decrypting something encrypted using the other key.

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.

Yes
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.
Yes
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
true
The primary cryptographic techniques for producing ciphertext involve symmetric and asymmetric encryption. Symmetric encryption uses a single key for both encryption and decryption, making it efficient for large amounts of data. Asymmetric encryption, on the other hand, uses a pair of keys (public and private) to enhance security, particularly for secure communications. Both methods rely on algorithms like AES for symmetric encryption and RSA or ECC for asymmetric encryption to transform plaintext into ciphertext.
Another name for public key encryption is asymmetric encryption. This term refers to the use of a pair of keys: a public key for encryption and a private key for decryption. Unlike symmetric encryption, where the same key is used for both processes, asymmetric encryption enhances security by ensuring that only the holder of the private key can decrypt messages encrypted with the corresponding public key.
