Cisco\u2019s Adaptive Security Appliance (ASA) was introduced in May 2005. It is an effective combination of the functionalities of Cisco PIX, IPS product lines and VPN 3000.<\/p>\n

In this post, we have put together a step-by-step guide for installing an SSL certificate on Cisco ASA 5510, one of the many versions from the Cisco ASA 5500 series. This series of security appliances by Cisco is one of the most popular hardware firewalls in the market.<\/p>\n

Learn How To Install an SSL Certificate on Cisco ASA 5510<\/strong><\/p>\n

Step 1<\/strong><\/p>\n

Download the intermediate (the CA.crt) and primary certificate (your_domainname_com.crt). Please save them to a location where you wish to keep all of your certificate files.<\/p>\n

Step 2<\/strong><\/p>\n

In ASDM, click on Configuration > Device Management
\n\"SSL-Installation-CiscoASA5510\"<\/p>\n

Step 3<\/strong><\/p>\n

Steps to Install an SSL Certificate from Cisco ASA Command Line<\/strong><\/p>\n

This is an alternative SSL installation method.
\nStep 1<\/strong>
\nEnter the following text from ciscoasa (config)#:crypto ca authenticate my.CA.trustpoint<\/p>\n

Here, \u2018my.CA.trustpoint\u2019 is the name of the trustpoint, which was created during your certificate request generation.<\/p>\n

Step 2<\/strong>
\nNow, enter the entire body of CA.crt file followed by the word \u2018quit\u2019 on a line by itself. The file CA.crt can be opened and edited with a standard text editor.Users need to enter the entire body of that file when prompted.
\nStep 3<\/strong>
\nEnter \u2018Yes\u2019<\/strong> when asked to accept the certificate.
\nStep 4<\/strong>
\nNext, enter \u2018Exit\u2019<\/strong> when the certificate has been imported successfully.With this step, your intermediate (or chain) certificate is installed. Now you need to install your_domainname_com.crt file.
\nStep 5<\/strong>
\nEnter the following line from the ciscoasa (config) #:crypto ca import my.CA.trustpoint certificate<\/p>\n

Here, \u2018my.CA.trustpoint\u2019 is the name of the trustpoint, which was created during your certificate request generation.<\/p>\n

Step 6<\/strong>
\nNow, enter the entire body of CA.crt file followed by word \u2018quit\u2019 on a line by itself. Users can open the your_domainname_com.crt file and edit it with a standard text editor.<\/p>\n

Users need to enter the entire body of that file when prompted. You shall soon receive a message that the certificate was imported successfully.<\/p>\n

How do I Troubleshoot the Installation Procedure?<\/strong><\/p>\n

Step 1<\/strong>
\nPlease check the status of your newly installed SSL certificate with the help of our SSL Checker tool<\/a>. However, to access this tool, the website needs to be publicly accessible.
\nStep 2<\/strong>
\nAlternately, you can also open the web browser and try visiting your website with secure \u2018https\u2019. Experts recommend that users test with both the web browsers, Internet Explorer and Firefox; because Firefox is known to give out a warning if your certificate is not properly installed.<\/p>\n

The server may not be listening on port 443 if you receive a browser warning or error message about the website not being available. Or if your website takes a very long time to open and times out eventually, then your firewall may be blocking the traffic on TCP port 443.<\/p>\n","protected":false},"excerpt":{"rendered":"
