This project is a Go reimplementation of concepts, protocols, tool designs,
and command-line interfaces from Impacket (https://github.com/fortra/impacket),
originally developed by SecureAuth Corporation and currently maintained by
Fortra. Impacket is distributed under its own permissive license. No Impacket
source code is included in this project; all code in this repository
(excluding the third-party components listed below) was written from scratch
in Go after studying Microsoft protocol specifications and Impacket's behavior.

Output formats and command-line flags of several tools in this project
intentionally mirror their Impacket counterparts to ease migration for
existing users. This functional compatibility does not constitute use of
Impacket's source code.

Third-Party Components
------------------------------------------------------------------------------

This product includes the following third-party software, each of which is
distributed under its own license. See the corresponding source files for
the full license text.

  * pkg/third_party/smb2/
    A vendored SMB2/SMB3 client library originally authored by Hiroshi Ioka
    and contributors, distributed under the BSD 3-Clause License.
    Upstream: https://github.com/hirochachacha/go-smb2

  * pkg/third_party/gokrb5/
    A vendored Kerberos 5 client library originally authored by Jonathan
    Turner and contributors, distributed under the Apache License, Version
    2.0. See pkg/third_party/gokrb5/LICENSE for the full text. The vendored
    copy has been modified by this project: the gokrb5 client constructors
    (NewWithPassword, NewWithKeytab, NewFromCCache) now require a KDCDialer
    as their first argument, KDC TCP/UDP I/O routes through the supplied
    dialer instead of net.DialTimeout, and unused subpackages (service/,
    spnego/) have been removed. See the commit log and KNOWN_ISSUES.md for
    the full change record.
