Isopoh.Cryptography.SecureArray (nuget): A managed class that can hold an array in RAM and zero it       on disposal. The code has the capability to throw if it cannot lock       the array in RAM or gracefully degrade to merely pinning the memory       to prevent the CLR from moving it and risking exposure to other part       of the executable.
