In my XP SP2 machine many cryptographic service providers are installed, but the relevant ones use the same rsaenh.dll:

"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Defaults\Provider\Microsoft Enhanced RSA and AES Cryptographic Provider (Prototype)" and
"..Base Cryptographic Provider v1.0" and
"..Strong Cryptographic Provider".

The base CSP in all Windows versions > 95 supports MD5 and SHA-1. On the other hand, the
"Microsoft Enhanced RSA and AES Cryptographic Provider (Prototype)" (Windows XP) and
"Microsoft Enhanced RSA and AES Cryptographic Provider" (Windows 2003)
provide support for the Advanced Encryption Standard cipher AES-128, AES-192 and AES-256, but AES is not supported on Windows NT, 2000 or 98.

Only the "Microsoft Enhanced RSA and AES Cryptographic Provider" on Windows 2003 supports the SHA-2 hash functions: SHA-256, SHA-384 and SHA-512. (See here.)

Anyway, for the enhanced CSP the right context selection is with type 24 (XP and 2003 only)

uhm just the version from the download centre ???

Is there a way of getting a alogirth for a file to find its unique id?

example...

234io24oiu432kj424hjk23 = word
435khkjhkjh54k43h5j435 = excel
fjkhl 3jl4h2j4h23kl4h32j4 = virus
4jh32hj432hj4g234kjhg324 = BrutusAe2

i made up the hashes lol soz as you may tell hehe

If you still get the error with AHK version 1.0.46.10 or later, make sure that there is nothing else in your script file, only the code posted above. When you see the error message window, press Ctrl-C to copy it to the clipboard, than paste it into your message and post it here.
Which ID? The MD5 hash is often used to check the integrity of a downloaded file.

dc iopy and paste and not werk... philpho thought i could use an md5 hash thing to get the signature of a file as used by anti-virus software to identify it it wont look for the name cuz you can change it so i wants to be able to see the script of an exe or get a signature from it.

I am not sure what you mean. If you want to find duplicate files, first sort the files by their size, and compute the hash (a CRC is sufficient) for the ones, which have equal sized pairs. External hash programs work, but if you want to use only Windows tools and AHK, read the files in variables and use Sean's script to call the Windows API hash. If the files are too large, you have to read them piece by piece (or use external hash programs).

yes i want to read each program .exe in the actual script language instead of an encryption so i want to be able to use


fileread,

to get the entire script of the .exe file no matter how big it is

Ran it in Vista

OK

Thanks! Nice to know it.

@Sean: Thanks.. Very useful for me. I can finally discontinue using an external DLL for the task.

It would be nice if we can have an AHK FileGetHash command. It will supplement FileInstall command well.

how do you get the hash from a file? you made examples from letters and sentences

Same Here....Vista Home Premium

The simplest is "FileRead, OutputVar, Filename", and use OutputVar as the first parameter of the MD5 (or HASH) function.

i tried fileread and it came up with the a problem it said error and wouldnt tell me what... well it said error with the path to my file
i used fileread and it said.
error
specifically M:\ServU\Servu.exe

It can be locked. It is enough to have an open explorer window, showing the file.

I doubt so, otherwise nobody could work with Explorer...
Now, if the program is running, it is enough to lock the exe file, indeed.
