CypherKeep — Credential Manager for Mac
Zero-cloud AES-256 vault for API keys, seeds & secrets.
Every breach starts with leaked credentials — API keys inenv files, seed phrases in Notes. CypherKeep is a native macOS vault. 100% local, zero cloud. • AES-256-GCM + Argon2id encryption • Live API key testing — 🟢 🟡 🔴 status in real time • BIP39/SLIP39 seed phrase validation • Touch ID unlock + clipboard auto-clear • Encrypted full-text search No accounts. No telemetry. No breach surface. Built with CryptoKit + SQLCipher.
I had API keys scattered across .env files, Notion, iCloud Notes, and Slack. One breach away from a cascade — so I built the tool I needed.
Why not existing managers? They either sync to the cloud (attack surface) or don't understand what an API key is.
The feature I'm most proud of: paste any key → auto-detects the provider → tests it live → 🟢🟡🔴. No curl, no docs, no context-switching. 12 providers supported at launch.
Would love your take on these decisions: • Argon2id at 64MB memory cost — too aggressive for older Macs? • SQLCipher over encrypted JSON — right call? • Which provider should I add to the testing engine next?
