/**
* This is the Message Digest Implementation of Turbine 2.1. It does not pad the
* Base64 encryption of the Message Digests correctly but truncates after 20
* chars. This leads to interoperability problems if you want to use e.g.
* database columns between two languages.
*
* If you upgrade an application from Turbine 2.1 and have already used the
* Security Service with encrypted passwords and no way to rebuild your
* databases, use this provider. It is bug-compatible.
*
* DO NOT USE THIS PROVIDER FOR ANY NEW APPLICATION!
*
* Nevertheless it can be used as the default crypto algorithm .
