Here's a way to do the conversion.  No ideas on the search.

class String
  def to_hex_string
    r = ''
    self.each_byte{|c| r << c.to_s(16)}
    r
  end
end

# unit test
require 'test/unit'

class TestString < Test::Unit::TestCase

  def test_convert
    assert_equal( '52494646', 'RIFF'.to_hex_string)
  end

end
