PGP / GPG Key Inspector
Paste an ASCII-armored OpenPGP public key block. The browser parses it locally and shows the version, algorithm, fingerprint, user IDs, subkeys, expiration, and key flags — without uploading anything.
100% client-side. The key never leaves your browser. If you paste a PRIVATE key block by mistake, the tool stops immediately and refuses to parse it.
Begins with -----BEGIN PGP PUBLIC KEY BLOCK-----. You can export one with gpg --armor --export <keyid>.
What you get
- Fingerprint & Key ID for the master key and all subkeys (v4 = SHA-1; v5/v6 = SHA-256).
- Algorithm and key size when the algorithm is RSA / DSA / ElGamal, or curve name for ECC keys.
- Creation and expiration dates derived from the public-key packet and self-signature subpackets.
- Key flags per subkey: certify, sign, encrypt (communications & storage), authenticate.
- User IDs on the key (with revoked / expired markers when detected).
Important caveats
- This tool does not verify signatures or build a web of trust — it only describes packet structure.
- Trust before encrypting: confirm the fingerprint with the recipient via a separate channel.
- For full verification use
gpg --import key.ascfollowed bygpg --check-sigs.
