WebFeb 1, 2024 · To start benchmarking RSA APIs we need a certificate with a private key. You can create a self-signed certificate if you don’t have one handy. Once we have a cert we can load it in [GlobalSetup] part of our benchmarks. We also need some data to sign. A random byte [] will do so I’m using UTF8.GetBytes on a hardcoded string to get that array.
