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?

I've got a bunch of hash from files in a folder
0x45B265C13EC41DD3272E547A837EF0604E06EF6C 0x73418EE0D435F0995DE000A0CB9A895B8031D62B 0x6FB325DDFA9AFCB148B815F41C94F5BBC3735E0B 0xE8BC5E1676E64E9EE77A7EBD56D910D60D453A2A 0xFF311E2FEC610B2E0A3169435CBC48D5B1B53A57 0x728EDF8577DF247CBC69ED6F2F9EACB3BF845150 0x8CABC5A4BDA856E0D0E884D0F4A335CB2457941D 0xCEBB04B9099141009329E13EDBD8B5CFB14A49A5 0xD7AA968FCF6AC9691F6ED801BA9291EBBBAFED71 0xBBBA76A66C54D53BADE77245D9F205F1EB9CC685 0x39DD14E5DB99F39F68182494C0B48CEFB5DDFDDF 0x32C2A01B523D973D933FC004237CAB4B792231BF 0x6AE1A10B7505DDABEECEAFD13B2EC2A8D7286587 how can I make a sum of the hash to have a hash that'd represent these hash as a single hash resultant of these ?.
I was thinking of sorting them and adding 'em to a string and hash that string but there may be a proper way to do it.
Any and all ideas are welcomed.

Hi every body. Today I want to share this small aplication(source code only) to check Hash in virustotal. (it is not a best coding practices example lol)
VirusTotal Hash Checker Allow you to check hash and files in virustotal.com using its Public API service.
Aplication Information.
-Add one or more Files
-Add all files in a folder
-Add a MD5
-Add a MD5 File List
-Automatic verification
-Check Single File
-Show Scan
-Show Scan in Web
-Open in Folder
-Clear List
Capture:
Files in the rar file.

Hi all, I need to generate an HMAC hash using SHA512 according to a certain API's specs and the only HMAC example I've seen () does not work as I need it do, even adapting it from a 64-bit blocksize to 512 and adding Ward's_SHA512 UDF.
I've tried the following:
Func _HashHMAC512($key, $message) $key = _StringRepeat("0", 512 - StringLen($key)) & $key ; keys shorter than blocksize are zero-padded ('?' is concatenation) $o_key_pad = BitXOR(0x5c * 512, $key) ; Where blocksize is that of the underlying hash function $i_key_pad = BitXOR(0x36 * 512, $key) ; Where ? is exclusive or (XOR) Return _SHA512($o_key_pad & _SHA512($i_key_pad & $message)) EndFunc
But, of course, it doesn't work (I suspect I'm doing something very blatantly wrong, but as I lack fundamental understanding about binary and hex number formats I can't see what's the issue right off the top of my head.)
Note: in my case $key will always by 68 characters long so it will always prepend the leading zeroes.
As a litmus test, I need to hash the message 1239348906120181 with the key ba63a816f030cefeea4803cd593569ce23f3815d0cc8c56d9194df6226dca2f0f48239698bc68991cfac387449b07b0f722f6f3df761dbc1fe8894dd65ff00b2 and receive 2610740031eeab61bbe6cd3f08daa6186ff0d59f5ec045dbb0e194fea8998b4f3d1da9aae0f718f8c126d6418302e081d68a82f0576eb266b68f26dc3459b62f as the output.
I've been working on this for the past 4-odd hours now, to no avail. I really, really don't want to have to restart my project in python or php or somesuch... or, for that matter, write the hash function in js, python, or php and somehow bootleg that single function's results into my au3 project. I would greatly appreciate any help from ye wise ents, even if it's just a nudge in the right direction.
