Important limitation
Compare fingerprints over a trusted channel before accepting a host or user key.
About SSH Public Key Fingerprint Viewer
SSH Public Key Fingerprint Viewer brings the required input, options and result into one focused workflow. Calculate SHA-256 and legacy MD5 fingerprints from an OpenSSH public key. The result changes when the source data or selected options change, so it is easy to run a second comparison.
For a typical workflow, use it to inspect a small representative sample before applying the same change in a production workflow. Start with a representative input, inspect the first result, then adjust one setting at a time if you need a different outcome.
Processing stays in the browser where the individual feature supports it. Live public checks use a protected, rate-limited site endpoint; avoid unnecessary sensitive data.
