A password checker that never sends the password
Build a tool that scores password strength and checks whether one has leaked, without ever sending the password.
Why it matters
Security roles screen for whether you think about what leaves the machine. Implementing a k-anonymity range query is a small, concrete answer to that question and it is memorable in an interview.
What you build
- An entropy-based strength score with clear feedback
- A k-anonymity range query against a breach corpus
- Hashing that never transmits the password itself
- A command-line interface with readable output
If you want more
- Passphrase generation
- A browser extension front end
Build it
Character-class rules reward P@ssw0rd1 and punish four random words. Entropy does not.
Material for the whole build
Shows applied cryptographic thinking and a real privacy-preserving protocol, not just a regex over password rules.
