GPG Key Info Extractor
Extract and view information from GPG public key blocks including key ID, fingerprint, algorithm, and user details.
Privacy & Security Notice
This tool processes GPG keys entirely in your browser. No key data is transmitted to any servers. Only paste public keys - never paste private keys. This is a simplified parser for basic information extraction. For complete key analysis, use dedicated GPG tools like GnuPG command line utilities.

Frequently Asked Questions
What is a GPG key and how does this tool help?
A GPG (GNU Privacy Guard) key is used for encrypting, decrypting, and signing data. This tool extracts key information like the key ID, fingerprint, algorithm, and user details from GPG public key blocks, helping you verify and inspect key metadata without needing command-line tools.
What information can I extract from a GPG public key?
The tool extracts key ID (short identifier), fingerprint (unique identifier), encryption algorithm, key length, creation date, user ID/email, and associated metadata. This information is useful for key verification, security auditing, and identity confirmation.
Is it safe to paste my GPG public key into this tool?
Yes, it's completely safe to use GPG public keys with this tool. Public keys are meant to be shared and contain no sensitive information. All processing happens in your browser with no data transmitted to servers. However, never paste private keys anywhere online.
What format should my GPG key be in?
The tool expects standard ASCII-armored GPG public key blocks that start with "-----BEGIN PGP PUBLIC KEY BLOCK-----" and end with "-----END PGP PUBLIC KEY BLOCK-----". This is the standard format you get when exporting GPG public keys.
Can I use this tool with PGP keys from other software?
Yes, this tool works with standard OpenPGP-formatted public keys generated by any compatible software including GPG, PGP Desktop, Kleopatra, and other OpenPGP implementations. The key format is standardized across different PGP/GPG software.
Why would I need to extract GPG key information?
Key information extraction is useful for verifying key authenticity, checking encryption algorithms, confirming key strength, validating user identities, security auditing, and ensuring you're using the correct public key for encryption or verification.
What does the key fingerprint tell me?
The fingerprint is a unique identifier for the key, similar to a hash. It's used to verify that you have the exact same key as someone else. When sharing keys, people often share fingerprints to ensure key authenticity and prevent man-in-the-middle attacks.
Can this tool verify if a GPG key is valid or expired?
This tool provides basic structural information about GPG keys. For complete validation including expiration dates, revocation status, and cryptographic verification, use full GPG software like GnuPG command-line tools or dedicated key management applications.
What if I get an error when pasting my GPG key?
Ensure your key block is complete with proper BEGIN and END markers, contains valid base64 content, and hasn't been corrupted during copying. The tool expects standard ASCII-armored format. If issues persist, try re-exporting the key from your GPG software.
How accurate is the key information extraction?
This tool provides basic key metadata extraction for common use cases. For production security applications, cryptographic verification, or detailed key analysis, always use official GPG tools like GnuPG that provide complete OpenPGP packet parsing and validation.
Can I extract information from encrypted or password-protected keys?
No, this tool only works with public keys and cannot decrypt or process encrypted private keys. Private keys should never be pasted into web tools anyway. Only use this tool with public keys that are meant to be shared.
What should I do with the extracted key information?
Use the extracted information to verify key authenticity by comparing fingerprints, check algorithm strength, confirm user identities, document key details for security audits, or validate that you have the correct public key before encryption operations.
