I am blocked... I just try to do this in C#

public static byte[] SignData(byte[] data, RSAParameters privateKey)
{

    using (RSA rsa = RSA.Create())
    {
        rsa.ImportParameters(privateKey);
         return rsa.SignData(data, HashAlgorithmName.SHA256, RSASignaturePadding.Pkcs1);
    }
}
public static bool VerifySignature(byte[] data, byte[] signature, RSAParameters publicKey)
{
    using (RSA rsa = RSA.Create())
    {
        rsa.ImportParameters(publicKey);
        return rsa.VerifyData(data, signature, HashAlgorithmName.SHA256, RSASignaturePadding.Pkcs1);
    }
}

But RSA on Crate is ... tricky.

Ring ? https://docs.rs/ring/latest/ring/index.html
Open SSL ? https://docs.rs/openssl/latest/openssl/

Maybe call C# or Java code

Or... Maybe do a Websocket server with all the RSA tools in usable from Rust.
