CSR Verification Tool

Check the CSR Key of Symantec, Thawte, RapidSSL, Comodo & GeoTrust

Use this CSR Decoder to decode your Certificate Signing Request and and verify that it contains the correct information. A Certificate Signing Request is a block of encoded text that contains information about the company that an SSL certificate will be issued to and the SSL public key. Once a CSR is created it is difficult to verify what information is contained in it because it is encoded. Since certificate authorities use the information in CSRs to create the certificate, you need to decode CSRs to make sure the information is accurate. To check CSRs and view the information inside of them, simply paste your CSR into the box below and the AJAX CSR Decoder will do the rest. Your CSR should start with "-----BEGIN CERTIFICATE REQUEST----- " and end with "-----END CERTIFICATE REQUEST----- ".
