Which type of cryptographic algorithms requires more than one key?
Asymmetric (public) key cryptographic algorithms require more than one key, specifically a pair of keys: a public key and a private key. The public key is used for encryption and can be distributed openly, while the private key is kept secret and used for decryption. This is in contrast to symmetric key cryptography, which uses a single key for both encryption and decryption.
Asymmetric Key Cryptography Asymmetric cryptography uses pairs of keys – a private one kept secret and a public one shared openly. You can use someone’s public key to encrypt a message, and only they can decrypt it with their private key.
