A script to generate a Ruby gem signing certificate of N years length. Temporary workaround until this is built into Rubygems.

gen_long_expire_gem_cert.rb

#!/usr/bin/env ruby

# Usage:
#   ./gen_long_expire_gem_cert.rb [email protected] [years]

# See also:
#   https://github.com/rubygems/rubygems/pull/1725
#   https://github.com/djberg96/sys-uname/issues/5

require 'rubygems'
require 'rubygems/security'
require 'rubygems/commands/cert_command'

# change the constant to equal 10 years
years = ARGV[1].nil? ? 10 : ARGV[1].to_i

Gem::Security::ONE_YEAR = 31536000 * years

puts "Building a #{years} year cert..."

c = Gem::Commands::CertCommand.new
c.build ARGV[0].to_s
