In the source code of openssh(my source code is 6.0 for Openbsd?? The content below is Rsa.h #ifndef RSA_H #define RSA_H #include <openssl/bn.h> #include <openssl/rsa.h> void rsa_public_encrypt(BIGNUM *, BIGNUM *, RSA *); int rsa_private_decrypt(BIGNUM *, BIGNUM *, RSA *); void rsa_generate_additional_parameters(RSA *); #endif /* RSA_H */ Question:

Hi all, After searching for a decent compiler backend for ages (google sometimes isn't helpful), I recently stumbled upon LLVM. Woot!! I work on bignum arithmetic (I'm a professional mathematician) and have recently decided to switch from developing GPL'd bignum code to BSD licensed code. (See http://www.mpir.org/ which I contributed to for a while - a fork of GMP). Please bear with

Hi, Has anybody produced diffs for openssh-2.3.0p1 for the rsa keyexchange problem that Core-SDI described ?

I have a very strange problem and can''t seem to figure it out. I have passenger 2.2.4 and apache 2.2 running a rails application. It ran fine for weeks when I decided to update Apache. I might also have messed with the users on this machine (OS X 10.5) Now when I start it, Apache starts up fine, loads passenger, and everything looks good. Then, after a while ( and I don''t

This error has been driving me nuts. It happens with no regularity or pattern and causes a 500 App error.

Hi, Patch attached for $SUBJECT. ismail

I have written the following function in RoR for my website . The function on execution gives an error for the Rmagick crop method , the error is wriiten after the function . I am using the same function(except for the change in name, rest everything is same) for cropping from left , right and bottom and they are working fine. All the left , right , top and bottomcrop functions are given the same

...ort, and I wanted to try LLVM as an apparently simpler and more portable system to my current design (a Haskell script which spits out mixed C and assembly). Porting the script to use the LLVM bindings instead of the current hack was pretty easy. But I have a few remaining questions: (1) Are bignums exposed to any higher-level language? It would be nice to be able to write all the code in C and compile it with Clang... but I need 256-bit integer support. (2) Is there a way to convince LLVM's register allocator to do the right thing on x86? I'm getting swaths of code like:...
