TacacsPlusCore

Simple .NET TACACS+ client library

Currently only supports Authentication requests. Support could be added for Authorization and Accounting.

Algorithms are implemented for CHAP, MS-CHAPv1, and MS-CHAPv2. CHAP has been tested against Cisco ISE and is working.

Calling the API to Authenticate is super simple.

// supports both IP address and DNS name
// you can use var sharedSecret.ToSecureString() to convert a regular string to a SecureString
var client = new TacacsPlusClient("192.168.1.100", 49, sharedSecret);
// Call Authenticate()
bool result = client.Authenticate(TacacsAuthenticationType.Chap, TacacsAuthenticationService.None, "user", password);
// An exception will be thrown if something goes wrong, otherwise true == success and false == fail

It's free. Enjoy!
