Convert SSL .cer extension to .crt extension

Hello All,

 

I got an ssl cert in .cer extension. But below doc says it needs to be in .crt extension.

 

How to convert .cer cert into .crt extension ?

1. Once you have received the new SSL certificate, copy it to the /config/ssl/ssl.crt/ directory.

    

2. tmsh install /sys crypto cert f5test.com_2015.crt from-local-file /config/ssl/ssl.crt/f5test.com_2015.crt
