About this utility
How to use SSH known_hosts Inspector
Parse OpenSSH known_hosts entries and calculate SHA-256 host-key fingerprints without contacting any host.
What to provide
Paste public known_hosts lines, including hashed hosts and @cert-authority or @revoked markers.
- Paste, type, or drag and drop a supported text file into the input area.
- Review the input and the clearly labeled output behavior.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
A host-key table with safe host display, key type, markers, comments, and SHA-256 fingerprints.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- All input and output remains in this browser tab and is never uploaded or saved. Compare fingerprints through a trusted channel. Parsing does not prove that a host or key is legitimate.
