PGP 키 생성기

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

1. Enter your Name and Email — they become the key’s user ID (Ada Lovelace <ada@example.com>).
2. Optionally set a Passphrase. It encrypts the private key; forget it and the key is unusable. Use the eye toggle to show it.
3. Pick an Algorithm: ECC (recommended), RSA 2048, or RSA 4096 (generation can take a few seconds).
4. Press Generate key pair and wait for the spinner to finish.
5. Copy or Download your public key (public-key.asc) — share this one freely.
6. Copy or Download your private key (private-key.asc) — store it somewhere safe.
7. Expand Revocation certificate and download it (revocation-cert.asc). Print it and store it offline for emergencies.

Examples

An ECC identity key

Input: name Ada Lovelace, email ada@example.com, algorithm ECC, no passphrase.

Output (truncated):

-----BEGIN PGP PUBLIC KEY BLOCK-----
xjMEZ9xKchYJKwYBBAHaRwBA9D4A5FSsD3vE…
=mBdA
-----END PGP PUBLIC KEY BLOCK-----

Fingerprint: 9A4C 82B1 6C9E 03F2 4721  88AB D05F 33E1 7C42 6019

An RSA-4096 key with a passphrase

Input: name Ada Lovelace, email ada@example.com, passphrase correct horse battery staple, algorithm RSA 4096 → a -----BEGIN PGP PRIVATE KEY BLOCK----- that asks for the passphrase when imported into GnuPG.

A revocation certificate

-----BEGIN PGP PUBLIC KEY BLOCK-----
Comment: This is a revocation certificate
…
-----END PGP PUBLIC KEY BLOCK-----

Good to know

• 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.
