Implementing QuartzLight in Java

This is the Java implementation of a modified version of the Quartz signature scheme, called QuartzLight. QuartzLight is not suitable for signature, as it is less secure than Quartz. However, it can be used as a starting point for a Java implementation of Quartz.

Parts of the source code can certainly be used in other projects. E.g. the finite field operations for GF(2^n), and also matrix operations (including LU decomposistion).

However, the software comes with no warranty as it is free of charge.
