Public Key

OpenPGP provides cryptographic identity verification that doesn't depend on centralized authorities. Your key pair—a private key you control and a public key you share—lets you sign messages, encrypt communications, and prove your identity across platforms.

Traditional identity verification online is fragmented. You might have accounts on dozens of services, but nothing cryptographically links them. If someone impersonates you on a new platform, there's no way to prove it's not you.

Fingerprint

An OpenPGP fingerprint is a unique cryptographic hash that serves as a compact identifier for a PGP public key. Think of it as a digital "thumbprint" for your encryption key—it's much shorter than the full key (typically 40 hexadecimal characters for modern keys) but uniquely identifies it.

Key Servers

I've uploaded my key to https://keys.openpgp.org so you can look up my contact information and verify that the fingerprint matches my email address. 

Because I've uploaded it there, you can lookup the fingerprint on Keyoxide and have their service verify the identity claims I've made in my public key.
