What it does
The PGP Key Generator creates OpenPGP key pairs — a public key you share with anyone who wants to send you encrypted mail or verify your signatures, and a private key you keep secret. It also produces a revocation certificate: a pre-made signature that marks the key as retired if it is ever lost, stolen, or compromised. Key generation runs 100% in your browser (via OpenPGP.js) — your private key is never transmitted, logged, or stored anywhere.
You choose between ECC (Curve25519) — the modern default: fast to generate, small keys, strong security — and the classic RSA in 2048- or 4096-bit sizes for compatibility with older OpenPGP implementations. An optional passphrase encrypts the private key at rest, so a stolen key file alone cannot be used.
How to use it
- Enter your Name and Email — they become the key’s user ID (
Ada Lovelace <ada@example.com>). - Optionally set a Passphrase. It encrypts the private key; forget it and the key is unusable. Use the eye toggle to show it.
- Pick an Algorithm: ECC (recommended), RSA 2048, or RSA 4096 (generation can take a few seconds).
- Press Generate key pair and wait for the spinner to finish.
- Copy or Download your public key (
public-key.asc) — share this one freely. - Copy or Download your private key (
private-key.asc) — store it somewhere safe. - Expand Revocation certificate and download it (
revocation-cert.asc). Print it and store it offline for emergencies.

- ECC vs RSA: ECC Curve25519 keys are ~300 bytes armored and generate in milliseconds; RSA-4096 keys are several kilobytes and can take tens of seconds in a browser. Both are considered secure; pick RSA only when you must interoperate with very old OpenPGP software.
- Revocation certificate: publish it to a keyserver (or give it to a friend) only when you want to retire the key. Anyone holding it can revoke the key — that is its power and its risk.
- Private: runs 100% client-side. Refreshing the page without downloading discards the key permanently — by design.
