SHA-2 Cryptographic hash function
« on: 2009-Nov-17 »
As mentioned yesterday, I wanted to get SHA-2 up and running.... And here it is.

I've implemented the 512 byte digest and not the lower versions.

SHA-2 is a verifiable system (and the code does match the results from the original routine too)

The letters "abc" produce the hex string : ddaf35a193617abacc417349ae20413112e6fa4e89a97ea20a9eeee64b55d39a2192992a274fc1a836ba3c23a3feebbd454d4423643ce80e2a9ac94fa54ca49f

One million "a" produces : e718483d0ce769644e2e42c7bc15b4638e1f98b13b2044285632a803afa973ebde0ff244877ea60a4cb0432ce577c31beb009c5c2c49aa2e4eadb217ad8cc09b

At the moment, it will only deal with passed strings - I'll get it dealing with data from files later on.

Code: GLBasic [Select]
LOCAL t$="abc"
SHA2_Initialise()
SHA2_Process(t$,LEN(t$))
DEBUG "Digest : "+SHA2_Finish$()+"\n"

And no, I dont understand any of it either - but it works, which is the main thing...

Very impressive work, congrats in getting this beast to inline!  :booze:
Cheers,

Good to see you ignored SHA-1 which is not as safe as it once was.  I don't pretend to understand it all (maths was never my strong suit) but I have had a long interest in Cryptography.  I was (before I 'retired' from coding) looking to create a crypto library as I have a habit of doing that whenever I start using any new language.  Glad to see someone else is getting into it instead.  So when can we expect to see all the other usual algorithms?  =D

Seriously though, well done mate!  :booze:

Glad you both like it!

The SHA-2 family may suffer from the same problem as SHA-1, although no attacks have been reported.  Using the 512 byte version certainly makes it harder to attack it though :)

Re: SHA-2 Cryptographic hash function
« Reply #6 on: 2012-Oct-23 »
Same for GLBasic IDE, Version: 10.283

I tried to verify the problem myself with no luck.
Yet it still leads me to wonder if it is a problem with the IDE
The original shows IDE Version: 7.177
What has been changed with the inline stuff for glbasic since then?

That is interesting - seems it doesn't like compounded statements.

Or rather it seems the command to generate them is now ignored :

Code: GLBasic [Select]
INLINE

#define a(x,str) \
{ \
}

It does do the same in 10.283 though..

ENDINLINE

Changing these lines should sort it :

Code: GLBasic [Select]
        #define UNPACK32(x, str) {  *((str) + 3) = (uint8) ((x)      ); *((str) + 2) = (uint8) ((x) >>  8); *((str) + 1) = (uint8) ((x) >> 16); *((str) + 0) = (uint8) ((x) >> 24);      }

        #define UNPACK64(x, str) {      *((str) + 7) = (uint8) ((x)      ); *((str) + 6) = (uint8) ((x) >>  8); *((str) + 5) = (uint8) ((x) >> 16); *((str) + 4) = (uint8) ((x) >> 24); *((str) + 3) = (uint8) ((x) >> 32); }

        #define PACK64(str, x)   {    *(x) =   ((uint64) *((str) + 7)      ) | ((uint64) *((str) + 6) <<  8) | ((uint64) *((str) + 5) << 16) | ((uint64) *((str) + 4) << 24) | ((uint64) *((str) + 3) << 32) | ((uint64) *((str) + 2) << 40) | ((uint64) *((str) + 1) << 48)  | ((uint64) *((str) + 0) << 56); }

        #define SHA512_SCR(i)    {  w[i] =  SHA512_F4(w[i -  2]) + w[i -  7] + SHA512_F3(w[i - 15]) + w[i - 16]; }

        #define SHA512_EXP(a, b, c, d, e, f, g ,h, j) { t1 = wv[h] + SHA512_F2(wv[e]) + CH(wv[e], wv[f], wv[g])+ sha512_k[j] + w[j]; t2 = SHA512_F1(wv[a]) + MAJ(wv[a], wv[b], wv[c]); wv[d] += t1; wv[h] = t1 + t2; }

Re: SHA-2 Cryptographic hash function

Thanks now it works.
For everyone that's dumb like me: you need to remember, that you need a function before the 1st Inline block, to close the main loop.


Oh no, it compiles, but it does not work correctly. E.g. the string "abc" produces the hash "000000a193617aba00000049ae2041310000004e89a97ea2000000e64b55d39a0000002a274fc1a800000023a3feebbd00000023643ce80e0000004fa54ca49f" which obviously is wrong. What can we do?

Use this instead :

        #define UNPACK64(x, str)   { *((str)+7)=(uint8)((x)); *((str)+6)=(uint8)((x)>>8); *((str)+5)=(uint8)((x)>>16); *((str)+4)=(uint8)((x)>>24); *((str)+3)=(uint8)((x)>>32); *((str)+2)=(uint8)((x)>>40); *((str)+1)=(uint8)((x)>>48); *((str)+0)=(uint8)((x)>>56); }

        #define PACK64(str,x) {         *(x)=((uint64)*((str)+7))       |((uint64)*((str)+6)<<8)        |((uint64)*((str)+5)<<16)       |((uint64)*((str)+4)<<24)       |((uint64)*((str)+3)<<32)       |((uint64)*((str)+2)<<40)       |((uint64)*((str)+1)<<48)       |((uint64)*((str)+0)<<56); }

        #define SHA512_SCR(i)   {       w[i]=SHA512_F4(w[i-2])+w[i-7]   +SHA512_F3(w[i-15])+w[i-16];    }

        #define SHA512_EXP(a,b,c,d,e,f,g,h,j)   {       t1=wv[h]+SHA512_F2(wv[e])+CH(wv[e],wv[f],wv[g]) +sha512_k[j]+w[j];      t2=SHA512_F1(wv[a])+MAJ(wv[a],wv[b],wv[c]);     wv[d]+=t1;      wv[h]=t1+t2;    }

With v10 i replaced these functions and still get errors.

Put MrTAToad's last batch of code in a separate secondary .gbas, and then in the main document of the project put the first 4 lines of code of the first post in this thread. It works here.
