Two different keys are used with one for encryption and the other for decryption. The decryption key cannot be derived from the encryption key.
A form of cryptosystem in which encryption and decryption are performed using two different keys, one of which is referred to as the public key and one of which is referred to as the private key. Also known as public-key encryption.
Encryption that permits the key used for encryption to be different for the key used for decryption. RSA is the most widely used asymmetric encryption algorithm.
