SSL-self-signed-certificate-creation-and-config

- 2017-07-20 Thursday -

Ted's first finding of instructions on setting up SSL and configuring Apache2 web server to use this encrypted protocol library:

• https://www.linux.com/learn/creating-self-signed-ssl-certificates-apache-linux

Copy of summary of steps from above instructions on-line:

"
Here's what we're going to do, in order:

1. Make sure Apache has SSL enabled.
   
2. Generate a certificate signing request (CSR).
   
3. Generate a self-signed certificate.
   
4. Copy the certificate and keys we've generated.
   
5. Tell Apache about the certificate.
   
6. Modify the VirtualHosts to use the certificate.
   
7. Restart Apache and test.

Note From SSL Config On Generic Server

 

STEP 1

ted@localhost:~$ sudo a2enmod ssl
Enabling module ssl.
See /usr/share/doc/apache2.2-common/README.Debian.gz on how to configure SSL and create self-signed certificates.
Run '/etc/init.d/apache2 restart' to activate new configuration!
ted@localhost:~$

STEP 2

ted@localhost:~$ # https://www.linux.com/learn/creating-self-signed-ssl-certificates-apache-linux
ted@localhost:~$ # STEP 2
ted@localhost:~$ sudo openssl req -new > new.ssl.csr
Generating a 1024 bit RSA private key

-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.

STEP 3

ted@localhost:~$ sudo openssl rsa -in privkey.pem -out new.cert.key
Enter pass phrase for privkey.pem:
writing RSA key

Getting Private key

ted@localhost:~$ sudo cp new.cert.cert /etc/ssl/certs/server-localhost.crt
[sudo] password for ted:
ted@localhost:~$ sudo cp new.cert.key /etc/ssl/private/server-localhost.key

Checking permissions of newly created private key file:

ted@localhost:/etc/ssl$ sudo su
# id
uid=0(root) gid=0(root) groups=0(root)
# cd private/
# ls -l
total 8
-rw-r--r-- 1 root root      887 2017-07-20 14:15 server-localhost.key
-rw-r----- 1 root ssl-cert 1679 2011-05-10 08:24 ssl-cert-snakeoil.key
# exit
exit
ted@localhost:/etc/ssl$ ls -l /etc/ssl/certs/server-localhost.crt
-rw-r--r-- 1 root root 993 2017-07-20 14:14 /etc/ssl/certs/server-localhost.crt
