Subject: Why openssl on windows produces error but not on centos to read pkcs12

Hi,

Its been days trying to figure out what could be wrong, hence I need
some one who already did tried to read pkcs12 certificate before.

This is code which I'm using both on centos and windows,

require 'openssl'

if ARGV.length == 2
 pkcs12 = OpenSSL::PKCS12.new(File.read(ARGV[0]), ARGV[1])
 p pkcs12.certificate
else
 puts "Usage: load_cert.rb "
end

Running this produces error on windows but not in linux/cygwin

Error:

OpenSSL::PKCS12::PKCS12Error: PKCS12_parse: mac verify failure from
(irb):21:in initialize' from (irb):21:innew' from (irb):21 from
C:/Ruby192/bin/irb:12:in `'

This has been so frustrating, that I tried to produce own certificate
own windows then tried again but it gives same error

I did these steps

- Use this software to create certificates http://xca.sourceforge.net/
- Exported UserCert2.crt, ruby reads correctly
 crt = File.read "UserCert2.crt"
irb(main):018:0> certificate = OpenSSL::X509::Certificate.new crt
=> #<OpenSSL::X509::Certificate subject=/CN=Noman Tariq,
issuer=/C=AU/ST=NSW/CN=CA, serial=2, not_before=2012-04-22 05:54:00 UTC,
not_after=2013-04-22 05:54:00
UTC>
- Exported to usercert.p12, ruby gives same error

OpenSSL::PKCS12::PKCS12Error: PKCS12_parse: mac verify failure from
(irb):21:in initialize' from (irb):21:innew' from (irb):21 from
C:/Ruby192/bin/irb:12:in `'


Thanks in advance for any clue or help,
Nauman
