This is needed when building with older Windows toolchains.

This is curious I think as the docs says:

This parameter is not used and should be set to NULL

So, the removed typecast is one thing but is this a pointer or not a pointer?

HCRYPTPROV_LEGACY is a typedef for ULONG_PTR, which is an integer type that's the size of a pointer, so it seems to make more sense to use 0 instead.

Wait, ULONG_PTR is not a pointer? I just have to double-check this!

If it is an integer with the size of a pointer, that's 64 bit on modern systems, while 0 will be a 32 bit integer, then shouldn't it be casted to 64 bit sized integer?

Update: nah, that shouldn't be necessary.
