Detailed explanation-1: -Explanation. An asymmetric key algorithm requires two keys: private (which is never shared) and public (which is openly available), so no key exchange is needed for communication. Messages are encrypted with the recipient’s public key and decrypted with the recipient’s private key.
Detailed explanation-2: -Asymmetric cryptography, also known as public-key cryptography, is a process that uses a pair of related keys–one public key and one private key–to encrypt and decrypt a message and protect it from unauthorized access or use.
Detailed explanation-3: -TLS/SSL uses asymmetric encryption to establish a secure client-server session while the client and server are generating symmetric encryption keys.
Detailed explanation-4: -Asymmetric encryption, also known as public key encryption, uses a public key-private key pairing: data encrypted with the public key can only be decrypted with the private key. TLS (or SSL), the protocol that makes HTTPS possible, relies partially on asymmetric encryption.
