A managed OpenSSL wrapper written in C# for the 2.0 .NET Framework that exposes both the Crypto API and the SSL API.
This a must for .NET developers that need crypto but don't want to use Microsoft's SSPI.
This wrapper is based on version 1.0.2a of libeay32.dll and ssleay32.dll.
The following is a partial example to show the general pattern of wrapping onto the C API.
Take DSA and the following C prototypes:
DSA * DSA_new(void);
void DSA_free(DSA *dsa);
int DSA_size(const DSA *dsa);
int DSA_generate_key(DSA *dsa);
int DSA_sign(int dummy, const unsigned char *dgst, int len,
unsigned char *sigret, unsigned int *siglen, DSA *dsa);
int DSA_verify(int dummy, const unsigned char *dgst, int len,
const unsigned char *sigbuf, int siglen, DSA *dsa);
Which gets wrapped as something akin to:
public class DSA : IDisposable
{
// calls DSA_new()
public DSA();
// calls DSA_free() as needed
~DSA();
// calls DSA_free() as needed
public void Dispose();
// returns DSA_size()
public int Size { get; }
// calls DSA_generate_key()
public void GenerateKeys();
// calls DSA_sign()
public byte[] Sign(byte[] msg);
// returns DSA_verify()
public bool Verify(byte[] msg, byte[] sig);
}
Make sure you have libeay32.dll and ssleay32.dll in the current working directory of your application or in your PATH.
In your .NET project, add a reference to the ManagedOpenSsl.dll assembly.
Take a look at the low-level C API documentation.
