Online toolkit for desktop engineers — SSH key permissions (chmod 600), networking, encryption, and security tools.

Online tools for desktop engineers

desktop.engineer is a free, open-source online toolkit for desktop engineers, system administrators and DevOps: every tool runs 100% in the browser, with no installation and no server.

SSH tools: generate SSH key pairs (RSA, ECDSA, Ed25519), inspect public keys, build a ~/.ssh/config file, convert OpenSSH to PuTTY and fix SSH key permissions with the chmod cheat sheet.
Security tools: strong password generator, application keys for .env files (JWT_SECRET, APP_KEY) and a checksum/hash checker.
Network tools: IP lookup with geolocation and a CIDR subnet calculator.
Server tools: Nginx configuration blocks, self-signed SSL certificates and cron expressions.
Data tools: JSON/YAML linter and formatter, universal format converter (JSON, YAML, CSV) and an encoder toolbox.

Built with Vue 3 and installable as a PWA, desktop.engineer is the desktop engineering toolkit that works everywhere — fast, private and free.
