Could you build this?
Yes It is a Git hook or CLI script that tweaks commit metadata (timestamps, commit message padding) in a loop until the SHA-1/SHA-256 hash converts into a prime number via a standard Miller-Rabin primality test.
Discussion
20 comments analyzed.
Competitors mentioned: git-vanity (similar vanity hash tool), git-vanity-sha (committer timestamp manipulation)
Concerns raised: Probabilistic primality testing lacks mathematical rigor vs deterministic algorithms, Sequential item IDs make timing attacks possible for getting specific IDs, Nonce in commit message is visible/not discrete enough, Performance overhead from repeatedly invoking git as subprocess
Feature requests: Use Baillie-PSW primality test instead of Miller-Rabin for provable primes, Store nonce in git commit header/trailer instead of message body, Manipulate committer email (user+nonce@domain) for discrete hash changes, Add git prime-log tool to show which commits are prime
