For macOS
Encrypted vaults without the terminal
Create, unlock, and lock encrypted folders on your Mac. Personal is free for one password vault; Pro adds Nostr, Amber, the menu bar, open at login, and more.
One vault free on Personal. Pro unlocks everything else — $14.99 once, paid in Bitcoin, no subscription. macOS 11+.
What it does
-
Vaults in Finder
Create a new encrypted folder or add an existing one. Unlocked vaults mount like any drive — drag files in and out as usual.
-
Unlock your way
A password, a Nostr key, or Amber as a remote signer. With Amber, your private key never leaves your phone.
-
Lock in one click
Unmount cleanly when you're done — and optionally snapshot a backup copy each time a vault locks.
-
Always within reach
Pro adds a menu bar tray and open-at-login — open a vault in Finder, unlock, or lock all without hunting for the window.
-
Proven encryption
Built on gocryptfs: AES-256-GCM with encrypted filenames. No new crypto to trust, and no terminal to wrangle.
-
Yours, offline
Files stay on your Mac and your license is verified locally. No account, no cloud, nothing phoning home.
How it works
-
Download the app
Install CryptKeeper on your Mac. You'll need macFUSE once — the app guides you if it's missing.
-
Buy a license
Pay with Bitcoin at checkout. You'll receive a license key by email within a few minutes.
-
Activate & use
Use CryptKeeper (Personal) free, or paste a Pro license key in Settings after purchase. Create vaults, mount them in Finder, lock when you're done.
