在哪里可以找到有关OpenSSL.Net的文档

Question

I've found DLL's ok, but I'm having trouble finding documentation.

I want to use C# to decrypt a string of text using a private RSA key. Documentation on OpenSSL.Net would be great, information on how to do this in particular would be amazing!

Edit:

The string itself was in Base64, and my private key is stored in a *.pem file. My final method is below, based on LOSTCODER's answer:

public string Decrypt(string textToDecrypt)
{
    byte[] payLoad = Convert.FromBase64String(textToDecrypt);

    StreamReader sr = new StreamReader("pemfilelocation.pem");
    string privateKey = sr.ReadToEnd();

    using (var key = CryptoKey.FromPrivateKey(privateKey, "myprivatekey"))
    {
        using (var rsa = key.GetRSA())
        {
            payLoad = rsa.PrivateDecrypt(payLoad, RSA.Padding.PKCS1);
        }
    }

    return Encoding.UTF8.GetString(payLoad);
}

Thankyou

Use the following routine to decrypt a byte[] using RSA private key. If you want to pass your encrypted 'string of text', use System.Text.Encoding.ASCII.GetBytes() to convert it to a byte[] (text is assumed to be ASCII encoded).

private static byte[] Decrypt(byte[] payLoad, string privateKey)
{
    using (var key = OpenSSL.Crypto.CryptoKey.FromPrivateKey(privateKey, null))
    {
        using (var rsa = key.GetRSA())
        {
            return rsa.PrivateDecrypt(payLoad, OpenSSL.Crypto.RSA.Padding.PKCS1);
        }
    }
}
