Ostermiller Java Utilities contain various components such as CSV parsing, Base64 Encoding, MD5 digest, String and Exec Helper classes. This requires the library ostermillerutils-1.08.01.jar to be in classpath. The following example shows getting MD5 hash of files and streams using MD5.getHashString() API.
