WebBoth for Public-key encryption and for digital signatures. The discussion here actually is just about the Public-key setting generally. It doesn't matter which of those two primitives we're talking about. So, remember the idea was that one party would generate locally a pair of public and private-keys and then put their public-key in some ... WebContrarily, in an asymmetric encryption algorithm, also known as public-key encryption, there exist two keys: one is public and can only be used for encrypting data, whereas the other one remains private and is used only for decrypting ciphertexts.
