SSL Shopper’s Useful Online SSL Certificate Debugging Tools Software & Sites 23 JAN 2014

certificate_good_serverI’ve mentioned SSL Shopper’s useful SSL Checker online utility before, but I don’t think I’ve every made a full note of the great set of SSL certificate debugging utilities that they currently host on their site.

So more for my reference than anything else, I’m going to go ahead and doing exactly that now:

SSL Checker: The SSL Checker makes it easy to verify your SSL certificates by connecting to your server and displaying the results of the SSL connection including what SSL certificate is installed and whether it gives out the correct intermediate certificates. The SSL Checker even lets you set up a reminder of a certificate’s expiration so you don’t forget to renew your certificate on time and avoid embarrassing error messages.

In other words, it will help you diagnose problems with your SSL certificate installation. You can verify the SSL certificate on your web server to make sure it is correctly installed, valid, trusted and doesn’t give any errors to any of your users.

CSR Decoder: 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.

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.

Certificate Key Matcher: You can use this Certificate Key Matcher to check whether a private key matches a certificate or whether a certificate matches a certificate signing request (CSR). When you are dealing with lots of different certificates it can be easy to lose track of which certificate goes with which private key or which CSR was used to generate which certificate. The Certificate Key Matcher tool makes it easy to determine whether a private key matches or a CSR matches a certificate.

The Certificate Key Matcher simply compares an md5 hash of the private key modulus, the certificate modulus, or the CSR modulus and tells you whether they match or not.

SSL Converter: Use this SSL Converter to convert SSL certificates to and from different formats such as pem, der, p7b, and pfx. Different platforms and devices require SSL certificates to be converted to different formats. For example, a Windows server exports and imports .pfx files while an Apache server uses individual PEM (.crt, .cer) files.

Useful Tools: SSL Checker Software & Sites 29 MAR 2013

certificate_good_serverWorried that your SSL certificate installation process seemed to run a little too smoothly?

Enter SSLShopper’s nifty SSL Checker, an online utility which will help you diagnose problems with your SSL certificate installation. You can verify the SSL certificate on your web server to make sure it is correctly installed, valid, trusted and doesn’t give any errors to any of your users.

To use the SSL Checker, simply enter your server’s hostname (must be public) in the text box and click the Check SSL button!

Basically the SSL Checker makes it easy to verify your SSL certificates by connecting to your server and displaying the results of the SSL connection including what SSL certificate is installed and whether it gives out the correct intermediate certificates. The SSL Checker even lets you set up a reminder of a certificate’s expiration so you don’t forget to renew your certificate on time!

Oh, and it has a code snippet which allows it to be added to your own site, though I’m not entirely sure why one would do that.

Useful little utility then.
