Re: SHA-2/HMAC for 32-Bit-Windows

Hi Helle,

confirmed.

I was testing it on Win 7 64bit but with the PB 32bit compiler.
The wrong calculations occurs then only if the PB-Debugger = On... i just figured out.

Running the code without the PB-Debugger, then all = OK.

So it seems that this (PB Bug?) will happens only on a 64bit ...

Re: SHA-2/HMAC for 32-Bit-Windows

Hi Helle, it's me again :)

on large *Sources it seems some HMAC calculations goes wrong.

For example, the SHA256 HMAC hex-digest of 1MB NULL-Bytes filled data, with a 32 byte NULL-Byte filed *key should be:
F7B04DA1D2F0C3F59F20FE10115CB839C7DB041333B78ADCE37E7FBC83222B2B

But HMAC_Calculate_32 ...

Re: SHA-2/HMAC for 32-Bit-Windows

Helle... works great now also on OSX 32bit.
Thank you very much.

Just one question (because i'm not able to "decrypt" the ASM code :) )

Is SSE2 required or does the code also run on non-SSE2 CPU's?

Thank you again for fxing the "@@" issue...

Greetings

Re: SHA-2/HMAC for 32-Bit-Windows

Hi
Thank you, works great on Win 7, 32 bit.

I try to compile it under OSX (32bit) but i got compile errors that "@@ is already defined".

Any Ideas?

Greetings
Melow

Re: PurePDF Version 2.0

Hi Klaus

i loaded PurePDF as lib. Is it possible to implement something like pdf_ASCII85_free(*pointer) ?
