SSH Key Inspector

Paste an OpenSSH public key line or a PEM PUBLIC KEY block — type, bit length, SHA256/MD5 fingerprints, and comment, all parsed client-side.

Input is capped at 64 KiB and parsed structurally — nothing is executed, nothing is sent anywhere. Private keys are rejected: paste public keys only.

Paste a public key to see its type, size, and fingerprints.
