More information about SHA2
Hi community,

I would like tu use SHA2 algoritm like here enter an Str (password) then get a Str crypted, but when i try it on esenthel with the method:

Code:
SHA2::Hash SHA2Mem(CPtr data, Int size);

I got an object SHA2::Hash wich contain:

Code:
struct{Byte  b[32];};
struct{UInt  i[ 8];};
struct{ULong l[ 4];};

And I don't know how to deal with this to have my Str cryped final.

Any tips ?

like a lot of things i havent start playing with hash atm, so little time and some much to do !

but isnt this what you are looking for ? C Hash& operator()( ); // finalize and get hash result

Yes,

SHA2::Hash gives you the hash result.
The hash is just a few bytes.

Is it my understanding you want to display the hash in text format?

If so you can use the TextHexMem function:
TextHexMem(&sha2.hash(), SIZE(sha2.hash()), ..);

RE: More information about SHA2
Ok I see thank, however I try it and i get a different result from the website of my first post, here is my code:

Code:
Str pass="coucou";
SHA2 hash;
hash.update(pass, SIZE(pass));
finalS=TextHexMem(&hash(), SIZE(hash()));

I try this too but same result:
Code:
Str pass="coucou";
SHA2::Hash hash=SHA2Mem(pass, SIZE(pass));
finalS=TextHexMem(&hash, SIZE(hash));

Result is: d2c5ecdb878dad5a80480d89672d0a7111d70bc8da3e8203be4e169c50ba5415

On the website with "coucou" i get:
110812f67fa1e1f0117f6f3d70241c1a42a7b07711a93c2477cc516d9042f9db

RE: More information about SHA2
Str is 16-bit char, maybe you want to use Str8
Also you need to use pass(), and pass.length()*SIZE(..) as the parameters for sha

RE: More information about SHA2
Ok but after try this in 16 and 8bit it still wrong, here are my try:

Code:
Str  pass="coucou";
SHA2::Hash hash=SHA2Mem(pass(), SIZE(pass())*pass.length());
Str finalS=TextHexMem(&hash, SIZE(hash));

Code:
Str8  pass="coucou";
SHA2::Hash hash=SHA2Mem(pass(), SIZE(pass())*pass.length());
Str8 finalS=TextHexMem(&hash, SIZE(hash));

Code:
Str  pass="coucou";
SHA2::Hash hash=SHA2Mem(pass(), SIZE(pass)*pass.length());
Str finalS=TextHexMem(&hash, SIZE(hash));

Code:
Str8  pass="coucou";
SHA2::Hash hash=SHA2Mem(pass(), SIZE(pass)*pass.length());
Str8 finalS=TextHexMem(&hash, SIZE(hash));

RE: More information about SHA2
SIZE needs to be SIZE(*pass())
Code:
Str8 pass="coucou";
SHA2::Hash hash=SHA2Mem(pass(), SIZE(*pass())*pass.length());
Str finalS=TextHexMem(&hash, SIZE(hash));
