Generate a free disposable email address (temp mail / throwaway email) that receives mail for 60 minutes. Inbound only — you cannot send or reply. Perfect for signups you don’t trust, confirmation codes, and keeping your real inbox spam-free.
Generate random MAC addresses for labs and testing — pure random hex, no OUI or unicast-bit management. Fill virtual networks credibly — local generation, free, no signup.
Generate RSA key pairs (2048/4096-bit) using the Web Crypto API. Export public and private keys as PEM strings. All client-side, no server uploads.
Generate SSH key pairs (ed25519/RSA) with copy-ready public and private parts. Set up server access in a minute — local Web Crypto, free, no signup.
RSA-2048 only — fixed at generation, no ECC option and no key-size picker. Exports save as public_key.asc and private_key.asc. Generate per identity, not per message.
Publish the public key (keyservers, profile); guard the private key offline with a strong passphrase. No revocation certificate is generated — plan revocation separately before you need it.
Yes for stored private keys — unencrypted key files on disk defeat the purpose. Managers plus hardware keys for high value.
No — generation runs locally in your browser. Keys never leave your device — back up private keys yourself.
