Asymmetric encryption is a cryptographic technique that uses a pair of keys: a public key for encryption and a private key for decryption. This method allows secure communication, as the public key can be shared openly, while the private key remains confidential. Only the holder of the private key can decrypt messages encrypted with the corresponding public key, ensuring that data remains secure even if the public key is widely distributed. Common algorithms used in asymmetric encryption include RSA and ECC (Elliptic Curve Cryptography).
What else can I help you with?
Public key encryption is also known as asymmetric 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.
Does a VPN use symmetric or asymmetric encryption?
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.
Why is encryption use?
Mostly for performance - symmetric encryption is much much faster (order of magnitudes) than asymmetric encryption.

What is the primary cryptographical techniques when producing ciphertext?
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.
