I am writing an API in C for authenticating user using ONVIF. I write some code to make authentication header. But when I sent these headers the server respond that “The security token could not be authenticated or authorized”
unsigned int nonce_int = 0, i = 0;
time_t utcTime = 0;
struct tm *timeInfo = NULL;
char sha1_input[100] = { 0 };
SHA1Context sha = { 0 };
nonce_int = GetRandomNumber();
encode_base64(sizeof(nonce_int), (char*)&nonce_int, nonceLen, noncestr);
utcTime = time(NULL);
timeInfo = localtime(&utcTime);
strftime(timestr, timeLen, "%Y-%m-%dT%H:%M:%SZ", timeInfo);
printf("\nTime in String Format = %s", timestr);
sprintf(sha1_input, "%d+%d+%s", nonce_int, utcTime, password);
SHA1Reset(&sha);
SHA1Input(&sha, (const unsigned char*)sha1_input, strlen(sha1_input));
if(!SHA1Result(&sha))
{
printf("\nERROR-- could not compute message digest");
}
else
{
memset(sha1_input, 0x00, sizeof(sha1_input));
/*sprintf(sha1_input, "%X%X%X%X%X", sha.Message_Digest[0], sha.Message_Digest[1],
sha.Message_Digest[2], sha.Message_Digest[3], sha.Message_Digest[4]);*/
sprintf(sha1_input, "%u%u%u%u%u", sha.Message_Digest[0], sha.Message_Digest[1],
sha.Message_Digest[2], sha.Message_Digest[3], sha.Message_Digest[4]);
printf("\nSHA1 Digest = %s", sha1_input);
encode_base64(strlen(sha1_input), sha1_input, digestLen, digeststr);
printf("\nSHA1 Digest Base64 Encoded = %s", digeststr);
}
after that I sent this request on HTTP using POST method this.

I synchronized the time. I think the problem is with my authentication headers. I did not find any useful documentation that specifies the exact data type and creation method for digest and other headers. any help will be appreciated. Thanks
I figured out the problem. I was using local time string rather than utc time string. this solved my problem. thanks
