Hi Berin,Dims,All
Now encoding is working, Thanks for help :).
Now problem is I try to decode the base64 encoded data. But my program
generates runtime error :((.I am using apache xml parser libs to do
that.
I kindly request to every one please help me to solve this issue.
Regards
G J Asanka Priyanjith
My code is
#include <openssl/sha.h>
#include <stdio.h>
#include <string.h>
#include <memory.h>
#include <xercesc/util/Base64.hpp>
#include <xercesc/util/XercesDefs.hpp>
#include <iostream>
XERCES_CPP_NAMESPACE_USE
char* doPasswordDigest(unsigned char*,char*,char*);
void hex_print(unsigned char*, int);
void main()
{
doPasswordDigest((unsigned char*)"szxczxcxzz","Y","Y");
}
char* doPasswordDigest(unsigned char *nonce_coded,char *created,char
*passwordin)
{
unsigned char *passwordout = NULL;
int para_size = 0;
char *para_cat= NULL;
char *md_return = NULL;
unsigned int x = 0;
unsigned int *TestI = &x;
unsigned int x2 = 10;
unsigned int *TestII = &x2;
//This one is not working,if I try to run the program It
will //generate runtime error.I just try to print out put and
check.
// std::cout << Base64::decode((const unsigned
//char*)nonce_coded,TestII,0);
//
char *nonce = "";
/*para_cat==nonce + created + password*/
para_size=strlen(nonce)+strlen(created)+strlen(passwordin)+1;
para_cat=(char*)malloc(para_size);
strcpy(para_cat,nonce);
strcat(para_cat,created);
strcat(para_cat,passwordin);
printf("%d\n",TestI);
/*SHA1(para_cat,para_size,passwordwout)==SHA-1 ( nonce + created +
password ) */
passwordout=(unsigned char*)malloc(20);
SHA1((const unsigned char*)para_cat,para_size-1,(unsigned
char*)passwordout);
hex_print(passwordout, 20);
std::cout << Base64::encode(passwordout,20,TestI,0);
/* I want to encode passwordout to Base64*/
free(para_cat);
free(passwordout);
return nonce;/*this is a just a test , after encodeing we have
return base64 encoded hash*/
}
void hex_print(unsigned char *c, int n)
{
int i;
for (i = 0; i < n; i++)
printf("%02x", c[i]);
printf("\n");
}

Subject: Re: how we can encode SHA-1 hash to Base64
Asanka,
I assume you want to do the encode using OpenSSL?
There is some stuff in the OpenSSL interface for Base64 in xsec that
might provide some pointers.
http://cvs.apache.org/viewcvs.cgi/xml-security/c/src/enc/OpenSSL/OpenSSL
CryptoBase64.cpp?rev=1.7&view=markup
If you want to do it using xsec, there are examples in DSIGReference for
doing it using xsec calls (setHash)
http://cvs.apache.org/viewcvs.cgi/xml-security/c/src/dsig/DSIGReference.
cpp?rev=1.23&view=markup
Cheers,
Berin
