Segmentation fault when generating new key with OpenSSL

Added by dimytch (Dimitri Peka) over 11 years ago. Updated over 11 years ago.

Status:
Closed
[ruby-core:53007]

Description

=begin
The code below makes ruby to crash

If I change
cert.version, cert.serial = 2
to
cert.version = 2
cert.serial = 2
it passes to the undefined variable ((|root_ca|)) as expected

#!/usr/bin/ruby

encoding: utf-8

require 'openssl'

def new_key
key = OpenSSL::PKey::RSA.new 4096
cert = OpenSSL::X509::Certificate.new
cert.version, cert.serial = 2
cert.subject = OpenSSL::X509::Name.parse '/DC=Ivan Ivanov/DC=8055645654/DC=h@h/DC=/OU=client/O=Kontora/C=KZ'
cert.issuer = root_ca.subject
cert.public_key = key.public_key
cert.not_before = Time.now
cert.not_after = cert.not_before + 2 * 365 * 24 * 60 * 60
ef = OpenSSL::X509::ExtensionFactory.new
ef.subject_certificate = cert
ef.issuer_certificate = root_ca
cert.add_extension(ef.create_extension("keyUsage","digitalSignature", true))
cert.add_extension(ef.create_extension("subjectKeyIdentifier","hash",false))
cert.sign(@@root_key, OpenSSL::Digest::SHA256.new)
return cert
end

puts new_key
