Creating server certificate

2018-10-07T14:05:04Z

Vvc:

=== Create openssl config file ===

Here is an example of server.cnf

<pre>
[ req ]
default_bits = 2048
default_md = sha256
distinguished_name = req_dn
req_extensions = cert_type
prompt = no

[ req_dn ]
# country (2 letter code)
C=US

# State or Province Name (full name)
ST=Virginia

# Locality Name (eg. city)
L=Leesburg

# Organization (eg. company)
O=Vadym Chepkov

# Organizational Unit Name (eg. section)
OU=IT

# Common Name (*.example.com is also possible)
CN=chepkov.com

# E-mail contact
emailAddress=vvc@chepkov.com

[ cert_type ]
keyUsage=digitalSignature,keyEncipherment
extendedKeyUsage=serverAuth
subjectAltName=DNS:www.chepkov.com,DNS:chepkov.com,IP:50.116.54.18
</pre>
*Note: Using a file like this with ''subjectAltName'' is the only way to generate a request that will result in a certificate that is valid for more than one ''name''.

=== Generate server private key ===
openssl genrsa -out server.key 2048

=== Generate certificate request ===
openssl req -new -key server.key -out server.csr -config server.cnf

Now you need to send your request to a certificate authority or if you have your own, sign the request (see [[Managing_Certificate_Authority#Signing_Certificate_Request|example]])
You will get server certificate server.crt

=== Generate self-signed certificate ===
openssl req -new -x509 -days 3650 -key server.key -out server.crt -config server.cnf -extensions cert_type

[[Category:OpenSSL]]

Managing Certificate Authority

2018-10-07T14:04:40Z

Vvc:

This article should help you to run your own '''certificate authority (CA)'''.
== Creating CA ==
We will keep all files related to our CA in directory '''/root/CA'''

=== openssl.conf ===
First, we will create OpenSSL configuration file. It can be stored anywere and referenced by environment variable
<pre>
export OPENSSL_CONF=/root/CA/openssl.conf
</pre>

Here is my file
<pre>
[ ca ]
default_ca = CA_default

[ CA_default ]
dir = /root/CA
new_certs_dir = $dir/certs
database = $dir/index.txt
unique_subject = no
certificate = $dir/cacert.pem
private_key = $dir/private/cakey.pem
serial = $dir/serial
crl = $dir/crl.pem
RANDFILE = $dir/private/.rand
x509_extensions = usr_cert
name_opt = ca_default
cert_opt = ca_default
copy_extensions = copy
default_days = 365
default_crl_days= 35
default_md = sha256
preserve = no
policy = policy_any

[ policy_any ]
countryName = supplied
stateOrProvinceName = supplied

emailAddress = vvc@chepkov.com

[ v3_ca ]

keyUsage = critical,keyCertSign,cRLSign
basicConstraints = critical,CA:TRUE,pathlen:1

authorityInfoAccess = caIssuers;URI:http://www.chepkov.com/ca.html
crlDistributionPoints=URI:http://www.chepkov.com/vvc-ca.crl

</pre>

=== Creating initial database ===
<pre>
cd /root/CA
mkdir certs private
chmod 700 private
echo 01 > serial
touch index.txt index.txt.attr
</pre>

=== Creating CA private key ===
openssl genrsa -out private/cakey.pem 2048

=== Creating CA certificate request ===
openssl req -new -key private/cakey.pem -out ca.csr

=== Self-signing CA certificate ===
openssl ca -selfsign -in ca.csr -keyfile private/cakey.pem -out cacert.pem -extensions v3_ca -verbose -enddate 361231235959Z

=== Signing Certificate Request ===
openssl ca -days 730 -in server.csr -out server.crt -extensions server

Make sure expiration day of the certificate does not exceed expiration day of your certificate authority. You don't have to specify '''days''' argument if you want to use default from openssl.conf

=== Revoking a certificate ===
openssl ca -revoke cert.pem

=== Generating Certificate Revocation List (CRL) ===
openssl ca -gencrl -out crl.pem
openssl crl -in crl.pem -out crl.crl -outform DER

Creating server certificate

2016-10-16T15:23:51Z

Vvc: /* Generate self-signed certificate */

=== Create openssl config file ===

Here is an example of server.cnf

<pre>
[ req ]
default_bits = 2048
default_md = sha1
distinguished_name = req_dn
req_extensions = cert_type
prompt = no

[ req_dn ]
# country (2 letter code)
C=US

# State or Province Name (full name)
ST=Missouri

# Locality Name (eg. city)
L=St. Louis

# Organization (eg. company)
O=IVK/VVC

# Organizational Unit Name (eg. section)
OU=VPS1 server

# Common Name (*.example.com is also possible)
CN=vps1.chepkov.com

# E-mail contact
emailAddress=root@ivk.com.au

[ cert_type ]
keyUsage=digitalSignature,keyEncipherment
extendedKeyUsage=serverAuth
subjectAltName=IP:209.20.74.232,DNS:vps1.chepkov.com,DNS:ivk.com.au
</pre>
*Note: Using a file like this with ''subjectAltName'' is the only way to generate a request that will result in a certificate that is valid for more than one ''name''.

=== Generate server private key ===
openssl genrsa -out server.key 2048

=== Generate certificate request ===
openssl req -new -key server.key -out server.csr -config server.cnf

Now you need to send your request to a certificate authority or if you have your own, sign the request (see [[Managing_Certificate_Authority#Signing_Certificate_Request|example]])
You will get server certificate server.crt

=== Generate self-signed certificate ===
openssl req -new -x509 -days 3650 -key server.key -out server.crt -config server.cnf -extensions cert_type
