Generate public private key pair c#
WebI've created a small helper NuGet package to create a X509 certificate based on public key and private (rsa) key. // Generate with: openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout private.key -out certificate_pub.crt string certificateText = File.ReadAllText ("certificate_pub.crt"); string privateKeyText = File.ReadAllText ... WebApr 20, 2024 · Like user2787670 explained, AES 256 is a symmetric cipher. This generates a RSA key pair. Exactly. Symmetric keys are good for encrypting large amounts of data, whereas asymmetric keys are better for small chunks. If two parties have their own key set, a typical scenario is to use asymmetric keys to securely exchange symmetric keys …

He then uses this key pair together with the receiver's public key to generate a secret key which can be used to encrypt the data. Finally, he sends the public key of the ephemeral key pair to the receiver together with the encrypted data.
