PGP Key Viewer
Parse ASCII-armored OpenPGP public keys in your browser to see algorithm, size, user IDs, creation date, and fingerprint.
Inspect an OpenPGP public key before you trust it
When someone emails you an ASCII-armored key block, you should verify the fingerprint and user IDs before encrypting sensitive data. This viewer parses the key locally with OpenPGP.js and lists algorithm details without sending the material to a server.
Security reminder
Paste only public keys. If you accidentally paste a private key block, the tool stops with an error instead of displaying secret material. Generate fresh keys with dedicated software and keep private keys offline.

Frequently Asked Questions
What is a fingerprint?
It is a short checksum of the public key material. Compare fingerprints out of band before trusting a key.
Can I verify signatures here?
This tool only displays metadata. Use your mail client or gpg for signature verification.
Why does parsing fail?
The block may be truncated, encrypted, or not a public key. Ensure the armor lines are intact.
Are subkeys listed?
Yes. Modern keys often include signing and encryption subkeys; the count appears when present.
Is any data logged?
No. Parsing happens entirely inside your browser session.
