SSL conversion from .p7b to .crt
Posted: Wed May 06, 2015 12:25 pm
I need to add a SSL cert to Nagios. I have the following cert provided to me by internal security sources.
Nagios.p7b
I've converted it to a .cer and a .pem. I think I need a conversion syntax to .crt to use with this procedure?

Hi jpye - quite often the crt and cer extensions are used interchangeably. They're both x509 certificates. The important part in your case is that they are PEM encoded.
Code: Select all
openssl x509 -in Nagios.cer -text -noout
If you don't get an error you're probably in good shape. If you do get an error you'll likely need to convert from DER encoding to PEM:
Code: Select all
openssl x509 -in Nagios.cer -inform der -outform pem -out Nagios.crt

Thank you, I had already verified that the cer was valid using openssl but I had not implemented it on the system. I'll go ahead and put the cert in motion and see what happens. Thanks for the reply.
