Unswappable memory needed is user space

I'm making a crypto program (under french law).
It crypts a file and then totally erase the uncrypted by filling it with
zero.

My problem is that if the crypting process is swapped out during
crypting, one could be able to recover parts of uncrypted file
in swap partition.

Is there a way to malloc a non swappable part of memory ?
