WebJun 28, 2024 · Public key cryptography is much, much slower than symmetric encryption (where both the sender and recipient have the same key). Using symmetric encryption requires, though, that a sender share the encryption key with the recipient in plain text, and this would be insecure. So by encrypting the symmetric key using the (asymmetric) public … WebDec 16, 2024 · In public key cryptography, it’s much the same way: there are two keys — one that can encrypt the data and the other that can decrypt it. These keys are separate yet mathematically related to each other. That’s because they’re generated using an asymmetric algorithm that binds the public key to the private one. fnhwsupport.zendesk.com https://pacificasc.org
