This is a command line program to generate a key pair as a JWK (JSON Web Key). It uses System.Security.Cryptography to generate a 4096 bit RSA key or a P-521 ECDSA key. The key pair is saved to two json files.
The .NET 8 SDK is required to build the program.
dotnet run -- --key-type rsa|ec --prefix <file-prefix>
Replace <file-prefix> with a descriptive name of your key. It will be part of the filenames. For example, dotnet run -- --key-type ec --prefix test will create two files: 'test_jwk.json' and 'test_jwk_pub.json'. The first file contains the key pair (including the private key), while the second file only contains the public key.
./publish.ps1
This outputs a win64 exe file in the publish folder which bundles all dependencies, including the .NET runtime.
