I am using openssl (on windows) to create a csr to go with a (test trial) Certificate. I have never done this before, and I have a question: After creating the private key, you create a csr file and you're asked to give personal information. One of the things it asks you is Common Name, which means domain name. I am presently only running off localhost. I am practicing how do create a https:// site.
Question: can I create a valid csr by doing something like localhost:82? If not, what should I do?
Simple answer: open your hosts file (C:\Windows\System32\drivers\etc\hosts) and come up with a fancy domain name:
# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# ::1 localhost
127.0.0.1 localhost
127.0.0.1 example.com # <<< Your fancy domain goes here !!!
Then, tell your webserver to serve HTTPS requests to example.com.
