# First, generate the key. You will be prompted to enter a password, but we will strip it out in the next step: | |
openssl genrsa -des3 -out server.orig.key 2048 | |
# Then, stip out the password: | |
openssl rsa -in server.orig.key -out server.key | |
# Edit the OSX openssl config file to include your alternate names. | |
# Edit the 'subjectAltName' field. E.g.: | |
# | |
# subjectAltName = "DNS:mydomain.com, DNS:*.beta.mydomain.com" | |
# | |
# You should use the wildcard for your primary (Common name) in the next step | |
# and set at least the root domain as a subjectAltName. This example will | |
# create a valid certificate for mydomain.com, *.mydomain.com and *.beta.mydomain.com | |
# If you do not set the root domain (mydomain.com) in this example as an alt name | |
# visitors will get a security warning when visiting https://mydomain.com, though not | |
# when visiting https://www.mydomain.com | |
sudo nano /System/Library/OpenSSL/openssl.cnf | |
# Generate the CSR: | |
openssl req -new -key server.key -out server.csr | |
# This step will require you to enter some information that will appear on the certificate. | |
# Only the first 4 fields plus the 'Common Name' (your main domain name) is required. | |
# For a wildcard subdomain, enter *.mydomain.com for the 'Common Name'. Here's an example: | |
# | |
# | |
# Country Name (2 letter code) [AU]:CA | |
# State or Province Name (full name) [Some-State]:Ontario | |
# Locality Name (eg, city) []:Toronto | |
# Organization Name (eg, company) [Internet Widgits Pty Ltd]:Your Company, Inc. | |
# Organizational Unit Name (eg, section) []: | |
# Common Name (eg, YOUR name) []:*.mydomain.com | |
# Email Address []: | |
# Finally, Check to see if it's as expected: | |
openssl req -text -noout -in server.csr | |
# Once you receive your certificate, you will probably have two or three .crt files. | |
# You'll probably have to concatenate them together into a single .crt (At least for Heroku or nGinx). | |
# E.g.: | |
cat STAR_mydomain_com.crt PositiveSSLCA2.crt AddTrustExternalCARoot.crt > bundle.crt | |
