When to use this tool
Review a certificate signing request before sending it to an issuer, especially its names and public key.
How to use it
- Paste the CSR PEM beginning with CERTIFICATE REQUEST, or use the CSR example.
- Inspect Subject, SAN, public key and the reported request-signature result.
Reading the result
A valid CSR signature does not prove domain ownership or guarantee issuance. Correct mistakes by creating a new request rather than editing encoded PEM by hand.
