Quick.Crypto functions do not work on 64bits Windows

[infpmandin]

All the types are defined as Cardinal (32 bits).

They should be declared as this:

type
  HCRYPTPROV  = ULONG_PTR;
  HCRYPTKEY   = ULONG_PTR;
  ALG_ID      = NativeUInt;
  HCRYPTHASH  = ULONG_PTR;

As a side note, those functions from advapi32.dll are listed as deprecated by Microsoft.
They should be replaced by https://learn.microsoft.com/fr-fr/windows/win32/seccng/cng-portal (but requires Vista/2008 or above).
