Certificate Decoder Tool

Verify your SSL Certificate is Correct

The Certificate Decoder allows you to instantly decode an SSL Certificate. Use this to decode your PEM, DER, or PFX encoded SSL Certificate and verify that all the information is correct. You can use this certificate decoder by simply pasting your certificate into the box below and the decoder will do the rest. Your Certificate Decoder should start with: -----BEGIN CERTIFICATE ----- and end with: -----END CERTIFICATE -----

Once the SSL Certificate is installed on the web server, you can use the SSL Checker to check and make sure it is installed correctly.
