Hello,
this is from the OpenCA INSTALL-0-8 Readme:
Note (not recommended):
If you have your own Root certificate which you would like to
use
instead of creating a new one you need to have it in DER and PEM
format. Copy the private key to
/usr/local/OpenCA/private/cakey.
My company have recently decided to move from Netscape tp OpenCA.
But we stiil want to use our old Netscape generated root cert with new
software.
The question is how to import .cer format file info OpenCA and easily
create
new client and server certificates signed with this .cer imported
