Data won’t be compromised if the public key is lost or stolen.In asymmetric Key cryptography, there are two keys, also known as key pairs: a public key and a private key. The public key is publicly distributed. Anyone can use this public key to encrypt messages, but only the recipient, who holds the corresponding private key, can decrypt those messages.Jan 19, 2023 · 1. The private key is faster than the public key. It is slower than a private key. 2. In this, the same key (secret key) and algorithm are used to encrypt and decrypt the message. In public-key cryptography, two keys are used, one key is used for encryption, and the other is used for decryption. 3. Asymmetric key cryptography, also known as public-key cryptography, is a cryptographic system that uses two keys, a public, and a private key, to secure communication and data transmission.
