mpi-genesis 21 * Actually it's the same code with only minor changes in the
mpi-genesis 22 * way the data is stored; this is to support the abstraction
mpi-genesis 23 * of an optional secure memory allocation which may be used
mpi-genesis 24 * to avoid revealing of sensitive data due to paging etc.
mpi-genesis 25 * The GNU MP Library itself is published under the LGPL;
mpi-genesis 26 * however I decided to publish this code under the plain GPL.
