Hash Calculator MD5 SHA256 vs Headmin!

Need a hash calculator that just works? HashCalc computes MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 the instant you type or paste — no upload, no wait, no guessing. Most "hash" tools send your text to a website or bury the digest you need under ads. HashCalc runs every algorithm locally on your device and shows the results side by side, so you can copy the exact digest you want and move on. WHAT YOU GET - Live digests for MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 as you type - Verify a download in one step: paste the expected checksum and see match or mismatch instantly - Compare two hashes side by side to confirm two files or strings are identical - Sign messages with HMAC using your secret key across the full SHA family - Checksum any file — HashCalc streams it through the hasher so even large files hash cleanly - A saved history of recent hashes plus a plain-language reference on MD5, SHA, CRC32 and HMAC PERFECT FOR - Developers signing API requests and webhooks with HMAC - Anyone verifying a downloaded ISO, installer or backup against its posted checksum - Security-minded users checking file integrity without touching the cloud - Students and learners who want to see how hashing actually works WHY NOT JUST USE A WEBSITE? Web hashers make you paste sensitive text into a server you don't control, and they break the moment you lose signal. HashCalc computes everything on-device, works fully offline, and never sends your input anywhere. PRIVACY Every digest is computed on your device. No accounts, no servers, no tracking — your text and files never leave your phone. FULL ACCESS The free app covers core hashing. A HashCalc membership unlocks everything: all six algorithms, verify and compare, HMAC signing, file hashing and saved history. Choose a weekly or yearly plan, or a one-time lifetime purchase — subscriptions renew until cancelled and can be cancelled anytime. Type your first string and watch the digests appear.

Headmin is a native admin console for Headscale, the open-source, self-hosted control server for Tailscale-based networks. Point it at your own server and manage your entire tailnet from your phone — no dashboard tab required. CONNECT TO YOUR OWN SERVER Enter your Headscale URL and API key once. Your credentials are validated and then stored securely on-device, in your phone's Keychain or Keystore — never on our servers, because we don't have any. Headmin talks directly to your Headscale instance. USERS List, create, rename and delete users in seconds. NODES See every device on your network at a glance: online status, IP addresses and tags. Rename a node, move it to a different user, expire its key, or remove it entirely. Generate pre-auth keys with custom expiry, reusable or single-use, tagged for your ACLs. ROUTES View every subnet route and exit node your devices advertise, and approve or disable them individually. ACL POLICIES Edit rules, groups, tag owners and hosts through a visual editor, or drop into a raw HuJSON view for full control. BUILT FOR SELF-HOSTERS Headmin has no backend of its own and no account system — it's a thin, secure client for the server you already run. Your data stays between your phone and your infrastructure. Requires an existing Headscale server and an API key (generate one with `headscale apikeys create`).
