**Generate NT Hash**
The NT hash is used by Microsoft and others for authentication. This
program `nthash` converts the standard input to UTF16 (little endian)
and applies the MD4 hash algorithm. This resulting 32 byte string is
printed to standard out.
*Use at your own risk*, pay attention to
[license and warranty](#license-and-warranty), and
[disclaimer on external links](#disclaimer-on-external-links)!
Requirements
------------
To compile and run `ntash` you need:
* [nettle ↗️](https://www.lysator.liu.se/~nisse/nettle/)
* [markdown ↗️](https://daringfireball.net/projects/markdown/) (HTML documentation)
Additionally it is expected to have `make` and `pkg-config` around to
successfully compile.
Some systems may require additional development packages for the libraries.
Look for `nettle-dev` or similar.
Build and install
-----------------
Building and installing is very easy. Just run:
make
followed by:
make install
This will place an executable at `/usr/bin/nthash`.
Usage
-----
Just feed `nthash` with the password on standard input. Please not that
`nthash` does not strip new lines from input. You may want to use `echo`
with option `-n`:
$ echo -n test | nthash
