Key Center 1.8.4 — First stable release

Key Center is a focused, local-first API key vault for Windows: one portable executable, one encrypted local file, one master password. No account, no cloud sync, no background service.

Highlights

  • One entry, many keys — perfect for multiple projects, environments or accounts of the same provider; the list shows the default key and the copy button copies it.
  • Categories, search and sorting — create, rename and delete categories, resize the sidebar, search by name/category/note, and sort by created/updated time or name.
  • Key details — open a card to view, copy, reveal/hide every key, change the default key, or jump to editing.
  • Safe export — Ctrl + E exports a category-grouped plaintext .txt after re-entering the master password.
  • Themes and appearance — dark / light / follow-system, Windows 11 Acrylic backdrop and rounded corners, high-DPI and multi-monitor support.
  • Auto-lock and window memory — remembers window size/position, sidebar width, sort order and theme; locks after inactivity; single-instance protection.
  • Local encryption — AES-256-CBC + PBKDF2-HMAC-SHA256 (210,000 iterations) + HMAC-SHA256; the master password is never stored and the app makes no network requests.

Downloads

File Description
KeyCenter.exe Single portable executable — download and run
