Fauthentic
Fauthentic is a gem designed for the sole purpose of making it easy to generate and handle self-signed SSL certificates in Ruby.
It uses the OpenSSL library, and therefore the primary generate method returns
an object containing a cert and key represented as OpenSSL::X509::Certificate
and OpenSSL::PKey::RSA.
Thanks
Thanks to @nickyp for posting his original script for generating a self-signed certificate, from which this library grew.
Usage
It's pretty simple:
Want a Certificate?
ssl = Fauthentic.generate
puts ssl.cert.to_pem
# => -----BEGIN CERTIFICATE----- ...
puts ssl.key.to_s
# => -----BEGIN RSA PRIVATE KEY----- ...Want to be more specific?
opts = {
common_name: "my.domain.com", # Default: "example.com"
country: "BE", # "US"
state: "saddened", # nil
org: "MyOrg", # "Test"
org_unit: "Test", # "Test"
email: "totally-secure-team@my.domain.com", # nil
expire_in_days: 365 # 30
serial: 1 # Current time in billionths of a second + random
}
ssl = Fauthentic.generate(opts)
cert_string = ssl.cert.to_pem
# => "-----BEGIN CERTIFICATE-----..."
key_string = ssl.key.to_s
# => "-----BEGIN RSA PRIVATE KEY----- ..."Want to read a certificate?
cert = Fauthentic.parse_cert(cert_string)
puts Fauthentic.extract_subject(cert)
# => {C: "US", O: "MyOrg", CN: "my.domain.com", ...}Want to make sure a key matches a certificate?
Just use the openssl gem's check_private_key method:
key = Fauthentic.parse_key(key_string)
cert.check_private_key(key) # => true
