[Verifying my OpenPGP key: openpgp4fpr:0x838665D9A693980D]

Installing Berkshelf 4.0.1 on Cygwin x64

Prerequisites

Ruby 2.2.4

Installation

Install Gecode

Obtain Gecode tarball

Installing Ruby 2.3.0 on Cygwin x64

Warning!

You won't get a fully-functional installation! At the time of writing, it turned out gem is kind of broken on Ruby 2.3.0. Ruby gem installation fails with an error like kernel_require.rb:54:in require': cannot load such file -- win32/resolv`.

Keybase proof

I hereby claim:

I am aspyatkin on github.
I am aspyatkin (https://keybase.io/aspyatkin) on keybase.
I have a public key whose fingerprint is 092B ECDF 2385 8B3F 3E84 A6BE 6060 7C61 1D53 57A6

To claim this, I am signing this object:

	require 'openssl'

	# Generate X509 CSR (certificate signing request) with SAN (Subject Alternative Name) extension and sign it with the RSA key
	def generate_csr(common_name, organization, country, state_name, locality, domain_list)
	# create signing key
	signing_key = OpenSSL::PKey::RSA.new 2048

	# create certificate subject
	subject = OpenSSL::X509::Name.new [
	['CN', common_name],
