Yay! Now your new hash of the latest commit is 12345672abd92a159f3886e08951f29ee7ce0041.

$ git log -1 --format=%H

Command Line Options

[--path] Path to working directory. default: current directory
[--pattern, -p] Pattern to match. default: 0000000
[--block, -b] log[2](how many hashes should be calculated in each thread). default: 20
[--jobs, -j] the number of threads that will be spawned to bruteforce. default: your max - 1

How it works

A commit hash of git is generated from commit object.
Commit object consists of

Tree hash
Parent hash
Author
- Name
- Email address
- Timestamp
Committer
- Name
- Email address
- Timestamp
Commit message

One of the easiest thing to configure (even after the commit is done) among these attributes above is committer's name.
Changing it may affect almost nothing but commit hash.

So, after a commit is done, by running Commit Artist, through changing committer's name and calculating commit hash and loop back unless it is beautiful, finally you can get a commit which have sophisticated hash.
