Inspect a certificate request and its embedded public-key information.
Use the guide alongside the working tool.
Open CSR Decoder →Working local example
Use Try sample in the tool to load a labeled demonstration.Inspect a certificate request and its embedded public-key information.
Prepare the right input
Paste a PEM certificate signing request.
Review requested identity, public key and signature algorithm.
Review before using the result
Export the decoded request metadata.
Decodes a CSR; does not validate organizational identity, approve issuance or verify possession through an external authority. Up to 128 KB DER.
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.
