Certificate Decoder

Use this Certificate Decoder to decode your PEM encoded SSL certificate and verify that it contains the correct information. A PEM encoded certificate is a block of encoded text that contains all of the certificate information and public key. Another simple way to view the information in a certificate on a Windows machine is to just double-click the certificate file. You can use this certificate viewer by simply pasting the text of your certificate into the box below and the Certificate Decoder will do the rest. Your certificate should start with "-----BEGIN CERTIFICATE----- " and end with "-----END CERTIFICATE----- ". Once you do the SSL install on your server, you can check to make sure it is installed correctly by using the SSL Checker.

If you want to decode certificates on your own computer, run this OpenSSL command:

openssl x509 -in certificate.crt -text -noout

Paste Certificate Text
