[jruby-dev] [jira] (JRUBY-6951) Unable to encrypt data and then decrypt it in MRI Ruby

[Tim Olsen (JIRA)]

Tim Olsen created JRUBY-6951 Unable to encrypt data and then decrypt it in MRI Ruby Issue Type: Bug Affects Versions: JRuby 1.7.0.RC2 Assignee: Unassigned Components: OpenSSL Created: 17/Oct/12 5:54 PM Description: I am hunting down a problem with the multipass gem that started appearing when we switched to jruby. I have narrowed down the problem to jruby generating encrypted data that another openssl implementation (such as MRI Ruby) is unable to decrypt. See my session below. I encrypt a message in jruby and then successfully decrypt it in jruby. But I am unable to decrypt it in MRI Ruby. $ rvm use jruby-head Using /Users/tim/.rvm/gems/jruby-head $ ruby --version jruby 1.7.0.RC2 (1.9.3p203) 2012-10-17 10a52b3 on Java HotSpot(TM) 64-Bit Server VM 1.7.0_07-b10 [darwin-x86_64] $ irb jruby-1.7.0.RC2 :006 > c = OpenSSL::Cipher::Cipher.new('aes-128-cbc') => #<OpenSSL::Cipher::Cipher:0x23a86a12> jruby-1.7.0.RC2 :007 > c.encrypt => #<OpenSSL::Cipher::Cipher:0x23a86a12> jruby-1.7.0.RC2 :008 > c.key = '1234567890123456' => "1234567890123456" jruby-1.7.0.RC2 :009 > c.padding = 1 => 1 jruby-1.7.0.RC2 :010 > encrypted = c.update('secret message') + c.final => "\xB4\x15\xE0`\xAC^\xBDq~b.\x96\xB3\xCB$\xD1" jruby-1.7.0.RC2 :011 > require 'base64' => false jruby-1.7.0.RC2 :012 > encoded = Base64.encode64 encrypted => "tBXgYKxevXF+Yi6Ws8sk0Q==\n" jruby-1.7.0.RC2 :013 > decoded = Base64.decode64 encoded => "\xB4\x15\xE0`\xAC^\xBDq~b.\x96\xB3\xCB$\xD1" jruby-1.7.0.RC2 :015 > c2 = OpenSSL::Cipher::Cipher.new('aes-128-cbc') => #<OpenSSL::Cipher::Cipher:0x73607ba9> jruby-1.7.0.RC2 :016 > c2.decrypt => #<OpenSSL::Cipher::Cipher:0x73607ba9> jruby-1.7.0.RC2 :017 > c2.key = '1234567890123456' => "1234567890123456" jruby-1.7.0.RC2 :018 > c.padding = 1 => 1 jruby-1.7.0.RC2 :019 > c2.padding = 1 => 1 jruby-1.7.0.RC2 :020 > decrypted = c2.update(decoded) + c2.final => "secret message" jruby-1.7.0.RC2 :021 > $ rvm use ruby-1.9.3-p194 Using /Users/tim/.rvm/gems/ruby-1.9.3-p194 $ ruby --version ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.3.0] $ irb 1.9.3p194 :001 > require 'openssl' => true 1.9.3p194 :002 > require 'base64' => true 1.9.3p194 :003 > decoded = Base64.decode64 "tBXgYKxevXF+Yi6Ws8sk0Q==\n" => "\xB4\x15\xE0`\xAC^\xBDq~b.\x96\xB3\xCB$\xD1" 1.9.3p194 :004 > c2 = OpenSSL::Cipher::Cipher.new('aes-128-cbc') => #<OpenSSL::Cipher::Cipher:0x007f9843803fa8> 1.9.3p194 :005 > c2.decrypt => #<OpenSSL::Cipher::Cipher:0x007f9843803fa8> 1.9.3p194 :006 > c2.key = '1234567890123456' => "1234567890123456" 1.9.3p194 :007 > c2.padding = 1 => 1 1.9.3p194 :008 > c2.update(decoded) + c2.final OpenSSL::Cipher::CipherError: bad decrypt from (irb):8:in `final' from (irb):8 from /Users/tim/.rvm/rubies/ruby-1.9.3-p194/bin/irb:16:in `<main>' 1.9.3p194 :009 > Environment: jruby 1.7.0.RC2 (1.9.3p203) 2012-10-17 10a52b3 on Java HotSpot(TM) 64-Bit Server VM 1.7.0_07-b10 [darwin-x86_64] Project: JRuby Priority: Major Reporter: Tim Olsen
