This repository contains a .NET assembly implementing the "Authentication and Security Layer" (SASL) framework. SASL specifies a protocol for authentication and optional establishment of a security layer between client and server applications and is used by internet protocols such as IMAP, POP3, SMTP, XMPP and others.
To use the library add the S22.Sasl.dll assembly to your project references in Visual Studio. Here's a simple example which instantiates a new instance of the Digest-Md5 authentication mechanism and demonstrates how it can be used to perform authentication.
using System;
using S22.Sasl;
namespace Test {
class Program {
static void Main(string[] args) {
SaslMechanism m = SaslFactory.Create("Digest-Md5");
// Add properties needed by authentication mechanism.
m.Properties.Add("Username", "Foo");
m.Properties.Add("Password", "Bar");
while(!m.IsCompleted)
{
byte[] serverChallenge = GetDataFromServer(...);
byte[] clientResponse = m.ComputeResponse(serverChallenge);
SendMyDataToServer(clientResponse);
}
}
}
}
The library supports the following authentication mechanisms:
- Plain
- Cram-Md5
- NTLM
- NTLMv2
- OAuth
- OAuth 2.0
- Digest-Md5
- Scram-Sha-1
- SRP
Custom SASL Security Providers can be implemented through a simple plugin mechanism.
