java.lang.Object

org.pentaho.reporting.libraries.base.util.PasswordObscurification

public final class PasswordObscurification
extends Object

This class handles basic password obscurification. Note that it's not really encryption, it's more obfuscation. Passwords are difficult to read, not impossible.

This implementation guarantees consistent results for all valid character ranges.
