::: NOM256 :::

A Cryptographic Hash Algorithm, in Python.
Outputs a 256-bit 64 character hash, 'hash-graph', and metadata, given a file.

Warning. Unstable and in progress

An example of a hash-graph, generated in 22.099 seconds from a 45 KB file:

Usage

1. Set up or rename a copy of the file you want to hash as meal.txt.

• This can be any document file, or a simple text file with just a password.
• It is recommended you create a new directory (/my-hashes for example) with your meal.txt and NOM256.py:

2. Run NOM256, in the same directory as your meal.txt file.

• You can run it in the command prompt:

$ python NOM256.py

• Once running, you'll be shown the estimated time left to complete. The hash rate is approximately 0.0425 seconds per 1,000 bytes (approximately 1,000 ASCII characters).

Time/seconds	Size/bytes or Total Characters
4.25e-5	1
0.0425	1,000
0.425	10,000
4.25	100,000
42.5	1,000,000

3. The following files will be written in the same directory/folder:

• outhash.txt with the hash as a single 64 character hexadecimal alphanumeric string.
  Example: B62F0E417874A438574C54B927B25DAFF30EB75872E3512D05F34503D8EF4742
• outhash-history.txt with the history of hashes within the directory as multiple lines of hash strings, including the last hash.
• outhash-test.txt. Similar to outhash-history.txt, with useful metadata.
• outhash.png with the hash as a unique 'hash-graph' PNG image file. Its colour will change depending on the hash too.

Hash-graphs are generated with a pseudorandom variable colour, generated by their hash, to aid in quicker dicernment between hashes at a glance.

These hashes were generated from a 45 KB file with a single character changed.
