Calculating Hash values

[Graeme]

I was looking for a way to calculate the sha512 value of files downloaded and eventually came across crypt.au3 in my include folder. It looks good but when I looked at the global constants the three values for Sha 2 are commented out. Is there a reason for that or should these be made available?

see _SHA1ForFile() and https://msdn.microsoft.com/en-us/library/windows/desktop/aa375549(v=vs.85).aspx

use 

CALG_SHA_512

0x0000800e

$arDllCall = DllCall($hAdvapi32Dll, "int", "CryptCreateHash", "ULONG_PTR", $hContext, "dword", 0x0000800e, "ptr", 0, "dword", 0, "ULONG_PTR*", 0)

Ciao.

Thanks for that.

The values are available, just uncomment them from the constants file. There was a decision a few years back to not make them visible because they're not supported in XP below SP3(?). They will work fine once they're uncommented though, as long as you're not using an OS that's too old.
