ec key new

[dave paxton]

So in the code it does this:

if (!EC_KEY_generate_key(pkey))
            throw key_error("CKey::MakeNewKey

So one then goes to EC_KEY.  You can do either here:

#include <string.h>
#include "ec_lcl.h"
#include <openssl/err.h>
#include <string.h>

EC_KEY *EC_KEY_new(void)
    {
    EC_KEY *ret;

    ret=(EC_KEY *)OPENSSL_malloc(sizeof(EC_KEY));
    if (ret == NULL)
        {
        ECerr(EC_F_EC_KEY_NEW, ERR_R_MALLOC_FAILURE);
        return(NULL);
        }

    ret->version = 1;   
    ret->group   = NULL;
    ret->pub_key = NULL;
    ret->priv_key= NULL;
    ret->enc_flag= 0;
    ret->conv_form = POINT_CONVERSION_UNCOMPRESSED;
    ret->references= 1;
    ret->method_data = NULL;
    return(ret);
    }

It goes on down the way a bit.  It loads the LCL H file and that pulls
in BN.  In BN it has a 64 bit number size for 32 bit systems.  Right
there one get's lost.

>From there how does one trace this out into something like a logic
diagram?  Can one load this into a program that shows the commands and
then shows the diagram for it with word sizes?
