create self-signed certificate for localhost

gistfile1.sh

# SSL self signed localhost for rails start to finish, no red warnings. 

# 1) Create your private key (any password will do, we remove it below)

$ openssl genrsa -des3 -out server.orig.key 2048


# 2) Remove the password

$ openssl rsa -in server.orig.key -out server.key


# 3) Generate the csr (Certificate signing request) (Details are important!)

$ openssl req -new -key server.key -out server.csr

# IMPORTANT
# MUST have localhost.ssl as the common name to keep browsers happy 
# (has to do with non internal domain names ... which sadly can be
# avoided with a domain name with a "." in the middle of it somewhere)

Country Name (2 letter code) [AU]:
...
Common Name: localhost.ssl 
...


# 4) Generate self signed ssl certificate 

$ openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

# 5) Finally Add localhost.ssl to your hosts file

$ echo "127.0.0.1 localhost.ssl" | sudo tee -a /private/etc/hosts

# 6) Boot thin

$ thin start --ssl --ssl-verify --ssl-key-file server.key --ssl-cert-file server.crt

# 7) Add server.crt as trusted !!SYSTEM!! (not login) cert in the mac osx keychain
# Open keychain tool, drag .crt file to system, and trust everything.

# Notes:
# 1) Https traffic and http traffic can't be served from the same thin process. If you want 
#    both you need to start two instances on different ports.

@dellryuzi
it's copying "127.0.0.1 localhost.ssl" at the end of the file /private/etc/hosts

Thin is a lightweight web server http://code.macournoyer.com/thin/

this saved my a$$ when setting up a Grunt task to allow local AngularJS client debugging, and proxying /api requests to a staging environment. 🎩 well done and thank you OP.
