SHA256 and Sha512


Recommended Posts

We have a few functions that are standard that are Vista+ only, there's precedence.

Documented of course. Plus with cryptography I think we have to be a little vigilant, as users often skim read the help file, so adding a warning message doesn't always get through.

My point was, there's precedence to adding the algorithms to the help file/constants, as long as they're commented on in the help file. Just because they don't work on some versions of XP isn't a reason to not include them, was all I was saying.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Hmm, I don't know. Other systems seem to be able to hash files. You need a dll? Now I'm confused.

You can manually create them, but the UDF doesn't do that, it uses the built-in (and hopefully thoroughly tested) functions that the OS provides. Which is by far a lot safer than rolling your own security hashes.

i see now, czardas.  You were looking at the removal of the old hashes (MD5 SHA1), whereas i was simply looking at the inclusion of the additional SHA2 options.  I agree that nothing should be removed.  

And I have to keep deleting my words because BrewMan keeps saying them before I can fix all my typos and grammar.

I edited my post above. I will expand further though. Firstly I asked in the MVP Forum about this, with the conclusion of "don't add guinness" because as you know I often get told I don't listen to the MVP community!

 With cryptography I really think adding a warning to these constants won't stop the few that don't read the help file thoroughly and thus we will receive reports of "said algorithm doesn't work!" or worse.

No removal has taken place just yet. Maybe in the future it will be considered.

LOL. It doesn't matter. I would not want AutoIt development to pander to a few individuals running systems that are no longer supported.

@boththose - Of course they are mainstream security features already in place whether they have flaws or not. Removing them is opening pandora's box.

I see no reason why we should care if people don't read the help file, they don't read it now on some of the simplest things, and we don't strip those out because some users are stupid do we?

What I want to know is how long are Sha-256 and Sha-512 going to last? Encryption algorithms are meant to be good for hundereds, if not thousands or even millions of years. Methods for verification should never really be removed. What if I were to use a SHA-1 hash as a password? It will be very strong, and totally broken by backwards incompatibility.

Include all available options.

Okay, no worries guinness. If Microsoft plan to remove support for hashing algorithms, I now feel that I can no longer rely on using them - so it shouldn't matter to me. The example I gave in post 29 is totally valid. I may have to come up with a durable verification method of my own. It's kind of like being between a rock and a hard place.

I figured something out already. A simple and basic checksum is all I need for what I'm actually doing. No need for a dll. I still need to figure out a suitable method. The way I'm using SHA-1 is overkill right now in any case. :)

_Crypt_HashFile uses _Crypt_HashData which in turn uses the Advapi32.dll and the function CryptCreateHash and using that function in the DLL you can use these values for the ALG_ID. Reading that page, it says you can use a lot more of the algorithms than are mentioned in the help file. What I would do if i were you, would be to try using those other values and see if they work, from what I read they should, but take note of the algorithms listed that don't work on XP SP2 and below.

Let us know if it works.

 

Yep, the link you provided is providing the effective functionality required for my purposes...

I just added the Global Const $CALG_SHA_256 = 0x0000800c to my own function as the pre requisites are already built into Crypt.au3

So Far I only tested with the Sha256 and all conversions are correct.  Only tested in 7 X64 Ultimate... will do others in the next few days but so far so good thanks a bunch!

 

 

For now I have added the following to the beta version of Crypt.au3, but have commented out. I'm sure sooner or later Windows XP support will be dropped by AutoIt.

; Global Const $CALG_SHA_256 = 0x0000800c
; Global Const $CALG_SHA_384 = 0x0000800d
; Global Const $CALG_SHA_512 = 0x0000800e

 

It works!

My guess is more will request this sort of thing as the NSA shenanigan is invalidated DES, and a few others of their developed backdoor-ed encryption algorithms  couple that with the previously demonstrated weaknesses in MD5 and Sha1 and a lot of devs are rushing around trying to close those holes...

Thanks guy's great help!

Great forum, Amazing Community!

I dont know how removal crept in this discussion rather then simply the inclusion of the newer ones.  Even if Microsoft stops using them for certificates (and rejecting certificates signed as such due to active exploits) does not mean they lose all functionality and should be removed.  I use MD5 for disc checksums in production (for speed benefits over the more secure algorithms), a 2^64 collision rate is of no consequence when i am simply validating media that should all be identical.

Encryption algorithms are frequently found to be lacking in real security, that's why new ones keep being invented. As computers get faster, and with more memory, and as crackers get better and better at finding holes, security needs to improve to go along with it.

What was true 10 years ago isn't true today, which is why no one uses MD5 for anything other than a simple hash comparison these days.

SHA-1 is long broken as a security tool, way back in 2005 the Chineese pooped on than parade... 

https://www.schneier.com/blog/archives/2005/02/sha1_broken.html

Currently SHA-2 based cyphers are the only reliable algorithm.  The larger the better the greater the bit count the better.  As for password, the real problem will be to have everyone on the same page as far as cypher compatibility on databases, primary on MySQL and a few other major ones.   I think we need to keep a close eye on this. 

Another problem with passwords is many are using NSA supported algorithms as they are considered military grade.  The only problem is the NSA backdoored them all as they took control of the "Open Source" developement or was able to effectively influence businesses to rewrite most of the effective ones as to provide themselves accessibility.

Thanks for all the background information - plenty of reading there :). I only need a basic checksum because the binary I wish to test is only verified after some heavy processing. The chances of even a short string producing an invalid match in my program are negligible. I'm also not using a hash as a password - it was just a passing thought that data could automatically verify its own integrity midway through some process without the need for any external input.

Much sensationalism here. Little practical results.

Drifting away from SHA-1 is understandable but still not a hurry in most use cases.

Avoiding NSA-compromised PRNG is certainly a bit more urgent, let it be only for showing they did the wrong move (again).
