// Package log4go provides level-based and highly configurable logging.
//
// Enhanced Logging
//
// This is inspired by the logging functionality in Java. Essentially, you create a Logger
// object and create output filters for it. You can send whatever you want to the Logger,
// and it will filter that based on your settings and send it to the outputs. This way, you
// can put as much debug code in your program as you want, and when you're done you can filter
// out the mundane messages so only the important ones show up.
//
// Utility functions are provided to make life easier. Here is some example code to get started:
//
// log := log4go.NewLogger()
// log.AddFilter("stdout", log4go.DEBUG, log4go.NewConsoleLogWriter())
// log.AddFilter("log", log4go.FINE, log4go.NewFileLogWriter("example.log", true))
// log.Info("The time is now: %s", time.LocalTime().Format("15:04:05 MST 2006/01/02"))
//
// The first two lines can be combined with the utility NewDefaultLogger:
//
// log := log4go.NewDefaultLogger(log4go.DEBUG)
// log.AddFilter("log", log4go.FINE, log4go.NewFileLogWriter("example.log", true))
// log.Info("The time is now: %s", time.LocalTime().Format("15:04:05 MST 2006/01/02"))
//
// Usage notes:
// - The ConsoleLogWriter does not display the source of the message to standard
// output, but the FileLogWriter does.
// - The utility functions (Info, Debug, Warn, etc) derive their source from the
// calling function, and this incurs extra overhead.
//
// Changes from 2.0:
// - The external interface has remained mostly stable, but a lot of the
// internals have been changed, so if you depended on any of this or created
// your own LogWriter, then you will probably have to update your code. In
// particular, Logger is now a map and ConsoleLogWriter is now a channel
// behind-the-scenes, and the LogWrite method no longer has return values.
//
// Future work: (please let me know if you think I should work on any of these particularly)
// - Log file rotation
// - Logging configuration files ala log4j
// - Have the ability to remove filters?
// - Have GetInfoChannel, GetDebugChannel, etc return a chan string that allows
// for another method of logging
// - Add an XML filter type

# NTLM Implementation for Go
This is a native implementation of NTLM for Go that was implemented using the Microsoft MS-NLMP documentation available at http://msdn.microsoft.com/en-us/library/cc236621.aspx.
The library is currently in use and has been tested with connectionless NTLMv1 and v2 with and without extended session security.
## Usage Notes
Currently the implementation only supports connectionless (datagram) oriented NTLM. We did not need connection oriented NTLM for our usage
and so it is not implemented. However it should be extremely straightforward to implement connection oriented NTLM as all
the operations required are present in the library. The major missing piece is the negotiation of capabilities between
the client and the server, for our use we hardcoded a supported set of negotiation flags.
## Sample Usage as NTLM Client
```go
import "github.com/ThomsonReutersEikon/go-ntlm/ntlm"
session, err = ntlm.CreateClientSession(ntlm.Version2, ntlm.ConnectionlessMode)
session.SetUserInfo("someuser","somepassword","somedomain")
negotiate := session.GenerateNegotiateMessage()
<send negotiate to server>
challenge, err := ntlm.ParseChallengeMessage(challengeBytes)
session.ProcessChallengeMessage(challenge)
authenticate := session.GenerateAuthenticateMessage()
<send authenticate message to server>
```
## Sample Usage as NTLM Server
```go
session, err := ntlm.CreateServerSession(ntlm.Version1, ntlm.ConnectionlessMode)
session.SetUserInfo("someuser","somepassword","somedomain")
challenge := session.GenerateChallengeMessage()
<send challenge to client>
<receive authentication bytes>
auth, err := ntlm.ParseAuthenticateMessage(authenticateBytes)
session.ProcessAuthenticateMessage(auth)
```
## Generating a message MAC
Once a session is created you can generate the Mac for a message using:
```go
message := "this is some message to sign"
sequenceNumber := 100
signature, err := session.Mac([]byte(message), sequenceNumber)
```

// As with the Type 1 message, there are a few versions of the Type 2 that have been observed:
//
// Version 1 -- The Context, Target Information, and OS Version structure are all omitted. The data block
// (containing only the contents of the Target Name security buffer) begins at offset 32. This form
// is seen in older Win9x-based systems, and is roughly documented in the Open Group's ActiveX reference
// documentation (Section 11.2.3).
//
// Version 2 -- The Context and Target Information fields are present, but the OS Version structure is not.
// The data block begins after the Target Information header, at offset 48. This form is seen in most out-of-box
// shipping versions of Windows.
//
// Version 3 -- The Context, Target Information, and OS Version structure are all present. The data block begins
// after the OS Version structure, at offset 56. Again, the buffers may be empty (yielding a zero-length data block).
// This form was introduced in a relatively recent Service Pack, and is seen on currently-patched versions of Windows 2000,
// Windows XP, and Windows 2003.

// Package log4go provides level-based and highly configurable logging.
//
// Enhanced Logging
//
// This is inspired by the logging functionality in Java. Essentially, you create a Logger
// object and create output filters for it. You can send whatever you want to the Logger,
// and it will filter that based on your settings and send it to the outputs. This way, you
// can put as much debug code in your program as you want, and when you're done you can filter
// out the mundane messages so only the important ones show up.
//
// Utility functions are provided to make life easier. Here is some example code to get started:
//
// log := log4go.NewLogger()
// log.AddFilter("stdout", log4go.DEBUG, log4go.NewConsoleLogWriter())
// log.AddFilter("log", log4go.FINE, log4go.NewFileLogWriter("example.log", true))
// log.Info("The time is now: %s", time.LocalTime().Format("15:04:05 MST 2006/01/02"))
//
// The first two lines can be combined with the utility NewDefaultLogger:
//
// log := log4go.NewDefaultLogger(log4go.DEBUG)
// log.AddFilter("log", log4go.FINE, log4go.NewFileLogWriter("example.log", true))
// log.Info("The time is now: %s", time.LocalTime().Format("15:04:05 MST 2006/01/02"))
//
// Usage notes:
// - The ConsoleLogWriter does not display the source of the message to standard
// output, but the FileLogWriter does.
// - The utility functions (Info, Debug, Warn, etc) derive their source from the
// calling function, and this incurs extra overhead.
//
// Changes from 2.0:
// - The external interface has remained mostly stable, but a lot of the
// internals have been changed, so if you depended on any of this or created
// your own LogWriter, then you will probably have to update your code. In
// particular, Logger is now a map and ConsoleLogWriter is now a channel
// behind-the-scenes, and the LogWrite method no longer has return values.
//
// Future work: (please let me know if you think I should work on any of these particularly)
// - Log file rotation
// - Logging configuration files ala log4j
// - Have the ability to remove filters?
// - Have GetInfoChannel, GetDebugChannel, etc return a chan string that allows
// for another method of logging
// - Add an XML filter type
