Inspect SPKI public keys, algorithms and SHA-256 fingerprints.
Use the guide alongside the working tool.
Open Public Key Inspector →Working local example
Use Try sample in the tool to load a labeled demonstration.Inspect SPKI public keys, algorithms and SHA-256 fingerprints.
Prepare the right input
Paste a PUBLIC KEY PEM block.
Review algorithm, size or curve and fingerprint.
Review before using the result
Export public metadata without private material.
SPKI PEM only. No trust, key-owner or compromise check. Unsupported algorithms are identified without being imported for cryptographic use.
Privacy and trust boundaries
Inputs remain in this browser. No online reputation, account, DNS or remote key lookup is performed. A static inspection is not a security certification.
Use the sample to learn the workflow. Clear sensitive input after use; private exports and clipboard contents require careful handling.
