Parse a CSR

You can parse a Certificate Signing Request (CSR) in the Reseller Control Panel (RCP) to view its contents and catch errors before submitting an SSL order. Parsing reduces the number of declined orders caused by malformed CSRs, and it can speed up validation by surfacing the DNS string or validation file ahead of purchase.

Before you begin

• RCP access: Sign in to the Reseller Control Panel.
• CSR text: Have the CSR for the web server that will host the certificate, including the BEGIN and END lines.
• Product details: Know which supplier and product you plan to purchase.

Step 1: Open the Parse CSR tab

1. In the Control Panel, click Trust.
2. Select the Parse CSR tab.

Step 2: Choose the supplier and service

1. From the Select a supplier drop-down list, choose the certificate provider.
2. From the Select a service drop-down list, choose the product.
3. For domain-vetted certificates, enter the domain name to associate with the certificate.

Step 3: Submit the CSR

1. Paste the CSR into the CSR field.
2. Click Parse CSR.
3. Review the parsed data shown on screen.

External CSR decoders

You can also use the CA's own decoder tools to inspect a CSR:

• DigiCert CSR Decoder
• Sectigo CSR Decoder
• Trustwave SSL Certificate Analyzer

Next steps

• Pre-stage validation: Add the DNS record or upload the validation file before submitting the order to speed up issuance.
• Place the SSL order: Submit the CSR through the standard order flow.
• Fix CSR errors: Regenerate the CSR on your web server if the parser flags an issue.
