It will calculate the hash MD5/SHA1/CRC32 of the files in any format.

NEED the standard library File.ahk.

DOWNLOAD Hash.ahk.

Thx.

I wonder why didn't u united in the one function that takes parameter for desired hash type

_________________

I wasn't sure if people would like it as it uses different functions for them.
I updated the script combining them into Hash(). SID = 0 for CRC32.

Why not using meaningfull things instead numbers:



With good interface, its nice for StdLib.

EDIT:
You can also check if first parameter is not a number. If so, you can treat it as a file name, so function becomes really practical. This introuduces dependency to File.ahk unless you paste the code, however, something which isn't true now.

_________________

I preferred numbers as then can easily use other ones too like MD2, MD4, or SHA256 etc if supported.
Anyway, I added another one Hash_str.ahk to the zip which accepts (only) the string CRC32/MD5/SHA1 as SID.


Making Hash() accept the file path really introduces a dependency on other script/Library even if it's not used.
In the current context, you can use any other means than File_WriteMemory() to prepare the buffer of data without dependency on unused script/Library.

Cool! Sean, if you are already in the advapi32.dll, can you figure out how to call AES properly? It should work on XP, 2003 and Vista, and could give us a fast and secure encryption.

How to do large files ?

Those that can't fit into memory, for instance 1GB movie. Acctually by default it can't be bigger then 64MB.
I wonder, if file is read in chunks in loop, how to sum up cheksums.


AES wuld be indeed very good to have.

Let me take a look at it, but I don't have prior knowledge on it so I don't know how much work it would require.

They support chunk of data.
It's already possible for CRC32 in its current form, but need a tweak for CryptHash... function. Can add any data anytime until CryptGetHashParam is first called.

Can someone explain to me why is this function not working on Windows XP Pro while in remote desktop session? It is running fine when logged in normal mode.

When running the function inside a remote desktop session, I get this result:



When running the function on the same computer but inside a normal session, I get this result:



Any help would be appreciated.

Just to point out that Hash.ahk isn't a library file and File.ahk seems to need the Crypt.ahk library file.
