About this utility
How to use SSH Key, CSR & Certificate Chain Studio
Inspect SSH public-key wire fields, X.509 certificate metadata, JWK parameters, and ASN.1 structure for CSRs and key containers.
What to provide
Paste one SSH public key, PEM block, certificate, CSR, public/private key, or JWK. Sensitive material remains only in component memory.
- 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 safe structural report, including fingerprints and certificate validity dates where available.
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
- Everything is processed in this browser tab. Input, filenames, keys, and output are never uploaded or saved. Structural parsing does not establish chain trust, revocation, key ownership, CSR signature validity, or safe key strength policy.
