Subject: Legacy encryption function...

Hello everyone, I have an old Java authentication web service that I
must use in my rails development. The service takes a username and an
encrypted password. I'm having trouble reproducing the same encryption
algorithm.

Here is the Java encryption function:
  public static String digest(String text)
  {
    MessageDigest mDigest = null;
    try
    {
      mDigest = MessageDigest.getInstance("SHA");


      mDigest.update(text.toUpperCase().getBytes("UTF-8"));
    } catch (NoSuchAlgorithmException nsae) {
      nsae.printStackTrace();
    } catch (UnsupportedEncodingException uee) {
      uee.printStackTrace();
    }
    byte[] raw = mDigest.digest();
    return new BASE64Encoder().encode(raw);
  }


Here is the Ruby encryption function:
...
require 'digest/sha1'
Base64.encode64(Digest::SHA1.hexdigest('ruby'))
...


Now here is the resulting String calling the Java function with the
string 'ruby':
"oJtN1kHfQdCCLFN7ATWgAxIH6bc="


Here is what I get with my Ruby function for the same string:
"MThlNDBlMTQwMWVlZjY3ZTFhZTY5ZWZhYjA5YWZiNzFmODdmZmI4MQ==\n"


So, anybody knows what I'm doing wrong?
