asymmetric key encryption

Asymmetric key encryption uses two linked but different keys: a public key and a private key. The public key can be shared openly and is used to encrypt information. The private key stays secret and is used to decrypt that information. This system allows someone to send an encrypted message that only the intended recipient can unlock, ensuring privacy. It also enables digital signatures, where a sender confirms their identity. This method provides secure communication without sharing secret keys, enhancing both data security and authentication.
