public class MakeDigest
extends App

Generate a digest (default MD5) for a given text.

This Java application makes a digest for a text given as

• command line parameter,
• a text input file
  or from a
• a text input box hiding the key entries for password digest.

The digest algorithms available are those of the Java platform. At Java6 (2009) those were MD2, MD5 (default) and SHA-1,
Hint: To this application MakeDigest (source) belongs a .properties file MakeDigest.properties that may be considered as part of the documentation and may answer open questions.
