Re: How to convert a byte array populated with hex values into decimal values

ontrac2h...@gmail.com (khumayun) — Thu, 07 Jan 2010 21:09:58 UT

hmm i just copied it into an unsinged long and by doing that it not
only converted it to decimal but i don't have to worry about big/
little endian since it was copied to a register aka unsigned long.
turn out to be pretty easy. ofcourse, if i was doing file io or over
the network byte transfer then this would not work.

Did you try a typical casting?
When I convert INT to HEX I use printf (%x,table[i]) or int i= (int)
table[i];

How to convert a byte array populated with hex values into decimal values

ontrac2h...@gmail.com (khumayun) — Wed, 06 Jan 2010 23:26:36 UT

Hey Guys,
I have finally got my HMAC output to a byte array that was
initialize as a hex. So all the values are in Hexadecimal and I want
to just take the first six values and convert them to decimal. At the
moment, I am developing on ubuntu 9.1 but I intend to port this to
freebsd maybe on a solaris box.

Happy new year!

This is just a thank you note to everyone here that helped me out,
specialy Vadym Fedyukovych and Geof Beier.
Cheers to you all!

ok, i'm going to use an StreamTransformationFilter.
byte key[]=
{'0','1','2','3','4','5','6',' 7','8','9','a','b','c','d','e' ,'f'};
byte iv[]=
{'1','2','3','4','5','6','7',' 8','9','0','a','b','c','d','e' ,'f'};

Re: Problem with using crypto++ 5.6 in Builder

delimitacione...@netscape.net (JPerez45) — Mon, 04 Jan 2010 07:35:59 UT

I received the same linking problems when usng the latest version, i ended up
using the 5.5.2 taken from the svn and almost everything went well, i guess
there is some code missing or the library was released in the middle of a
cleaning, also it seems you don't need the dll in builder, only the lib file

I had to use the 5.5.2 (i had to download the full tarball from
sourceforge) because the one i downloaded from the website kepped
sending linking errors with my project , i'm currently using it but is
not easy to integrate with the VCLs.
This is what i got from the other version:

Hi,
I haven't built or run your code. But here:
you would appear to be encrypting whatever 56 bytes follow your
plaintext on the stack in addition to your plaintext.

Hi.
I did some works about DES in java. All perfect but it's slow. Now i
am doing the same but in C++.
I saw this page : [link] and i
want to check if these examples work flawless but it didnt't .......

Custom filter problem

djorge...@gmail.com (djorge) — Sat, 02 Jan 2010 19:01:41 UT

Hi all,
i'm new to Crypto++ and need some help please.
I want to do a custom filter that basically takes a passphrase,
generate salt for key derivation (using PKCS5) and encrypts data
coming from the chain to the outer chain.
The idea is to use the custom filter like:
std::string cyphertext;
CryptoPP::StringSource( PlainText, true,

Re: RTLD_GLOBAL and libcryptopp.so crash

alekc...@googlemail.com (alekcey) — Mon, 28 Dec 2009 19:24:07 UT

Hi Jeff,
Do you mean that cryptopp needs patching?
If so, can you provide this patch for cryptopp?
Is this issue can be fixed in cryptopp upstream?

Borland C++ Builder 6 compile

yog...@interklasa.pl (YogurT) — Mon, 28 Dec 2009 12:18:04 UT

Hello!!!
I have to add Crypto++ to my project in Builder C++ 6. I have problems
with static linking. Is there any patch or solutions that can make
Crypto++ able to compile on BBC32?

Hi All,
Here's an issue that should be raised, though I'm not sure what to
make of it. It is either a GDB bug, or the runtime linker is
channelling *all calls* to get the RNG (ie, SO1::GetRng and
SO2::GetRng) though a single function (SO1::GetRng) since s_rng is
static.
In the trace below, notice that GDB switches thread contexts. However,

RTLD_GLOBAL and libcryptopp.so crash

noloa...@gmail.com (Jeffrey Walton) — Fri, 25 Dec 2009 01:26:50 UT

Hi All,
I wanted to put some findings in play for those interested,
particularly David and Zooko. Previous threads have had problems with
obtaining desired results with EH and RTTI due to object/address
equality. This in turn forced folks to call dlopen() with RTLD_GLOBAL,
which had side effects on other Crypto++ objects in libcryptopp.so

Re: errors with multiple loading cryptopp as shared lib on Linux

noloa...@gmail.com (Jeffrey Walton) — Thu, 24 Dec 2009 03:13:15 UT

Hi David,
I was not able to duplicate the issue. My setup had a traditional EXE
using cryptopp.so directly, with 3 SOs (loaded by the EXE) that each
used cryptopp.so. I guess mine looked more like:
EXE -> cryptopp.so
EXE-> SO1
EXE-> SO2
EXE-> SO3
SO1 -> cryptopp.so
SO2 -> cryptopp.so
SO3 -> cryptopp.so
