====== SSL ======
|
|
|
|
Be your own SSL Certificate Authority.
|
|
|
|
This tutorial is based on the domain ''nextcloud.home''. So change the domain to your specific domain.
|
|
|
|
It is also important that the domain address gets redirected from your router. This can also be set in the ''/etc/hosts'' file of your computer, but to reach the domain on every device, it is easier to change this directly in the router:
|
|
|
|
<code>
|
|
nextcloud.domain SERVER-IP
|
|
</code>
|
|
|
|
|
|
===== Generating the private key and root certificate =====
|
|
|
|
<code>
|
|
openssl genrsa -des3 -out myCA.key 2048
|
|
</code>
|
|
|
|
<code>
|
|
openssl req -x509 -new -nodes -key myCA.key -sha256 -days 1825 -out myCA.pem
|
|
</code>
|
|
|
|
Change the following information as you wish. It appears when you view the certificate through your browser.
|
|
<code>
|
|
Country Name (2 letter code) [AU]:
|
|
State or Province Name (full name) [Some-State]:
|
|
Locality Name (eg, city) []:
|
|
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
|
|
Organizational Unit Name (eg, section) []:
|
|
Common Name (e.g. server FQDN or YOUR name) []:
|
|
Email Address []:
|
|
</code>
|
|
|
|
|
|
===== Installing your root certificate on all the devices =====
|
|
|
|
You'll need to create a ''myCA.pem'' file on every device and copy the content of cat ''myCA.pem'' file wherever you created it in section [[#generating-the-private-key-and-root-certificate]].
|
|
|
|
|
|
==== Arch Linux ====
|
|
|
|
<code>
|
|
sudo trust anchor --store myCA.pem
|
|
</code>
|
|
|
|
|
|
==== Android ====
|
|
|
|
''Settings'' - ''Security'' - ''Encryption and credentials'' - ''Install a certificate''
|
|
|
|
Check under:
|
|
|
|
''Settings'' - ''Security'' - ''Trusted credentials'' - ''User''
|
|
|
|
|
|
===== Creating CA-Signed certificates for your domains =====
|
|
|
|
<code>
|
|
openssl genrsa -out domain.home.key 2048
|
|
</code>
|
|
|
|
<code>
|
|
openssl req -new -key DOMAIN.home.key -out DOMAIN.home.csr
|
|
</code>
|
|
|
|
<code>
|
|
nano DOMAIN.home.ext
|
|
</code>
|
|
|
|
<code>
|
|
authorityKeyIdentifier=keyid,issuer
|
|
basicConstraints=CA:FALSE
|
|
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
|
|
subjectAltName = @alt_names
|
|
|
|
[alt_names]
|
|
DNS.1 = DOMAIN.home
|
|
</code>
|
|
|
|
|
|
==== Script ====
|
|
|
|
Create the file in ''nano /etc/nginx/ssl/ssl.sh''.
|
|
|
|
<code>
|
|
#!/bin/sh
|
|
|
|
if [ "$#" -ne 1 ]
|
|
then
|
|
echo "Usage: Must supply a domain"
|
|
exit 1
|
|
fi
|
|
|
|
DOMAIN=$1
|
|
|
|
openssl genrsa -out $DOMAIN.key 2048
|
|
openssl req -new -key $DOMAIN.key -out $DOMAIN.csr
|
|
|
|
cat > $DOMAIN.ext << EOF
|
|
authorityKeyIdentifier=keyid,issuer
|
|
basicConstraints=CA:FALSE
|
|
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
|
|
subjectAltName = @alt_names
|
|
[alt_names]
|
|
DNS.1 = $DOMAIN
|
|
EOF
|
|
|
|
openssl x509 -req -in $DOMAIN.csr -CA myCA.pem -CAkey myCA.key -CAcreateserial \
|
|
-out $DOMAIN.crt -days 825 -sha256 -extfile $DOMAIN.ext
|
|
</code>
|
|
|
|
<code>
|
|
chmod +x ssl.sh
|
|
./ssl.sh domain.home
|
|
</code>
