Bug#743746: jruby: has poor cryptographic support

[brian m. carlson]

Package: jruby
Version: 1.5.6-7
Severity: normal

JRuby has really bad cryptographic support.  First, many algorithms are
missing.  The output directs me to the jruby-openssl gem, but that isn't
packaged.  If JRuby requires that gem in order to be as functional as
MRI, then it needs to be packaged and be an appropriate dependency (at
least a Recommends, if not a Depends) of jruby.  In this era,
cryptography is not an optional component.

Second, JRuby uses the wrong names for algorithms.  Running the attached
program (I have snipped the huge traceback that happens every time jruby
runs):

  vauxhall ok % ruby /tmp/sha256.rb
  Digest supports 'SHA256'
  Digest doesn't support 'SHA-256'
  SHA256 object exists
  vauxhall ok % env -u TZ jruby /tmp/sha256.rb
  JRuby limited openssl loaded. http://jruby.org/openssl
  gem install jruby-openssl for full support.
  Digest doesn't support 'SHA256'
  Digest supports 'SHA-256'
  SHA256 object does not exist

Notice that for the same algorithm, JRuby uses a different name, and it
doesn't support the SHA256 class that MRI has since at least 1.8.7.
This makes it impossible to write a program that works on both.
