How it works


A commit hash of git is generated from commit object.
Commit object consists of "tree hash", "parent hash", "author info", "committer info" and "commit message".
Author info and committer info each have "name", "email address", "timestamp".

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.


Use this tool on your own responsibility.
This tool is absolutely helpless with signed commit.
