Signing data with user specified Key
Hello, I am using GPG4Win and have to sign data with a specified key through my code in C++.But I didn't find much help on how to specify key for signing data in GPG document. Please find the below lines of code I am using for signing data: error = gpgme_op_sign(context,Plaindata,Signdata,GPGME_SIG_MODE_NORMAL); PRet = (char*)gpgme_strerror(error) ; gpgme_sign_result_t result = gpgme_op_sign_result(context); Thanks & Regards Sandhya Sharma # " This e-mail and any attached documents may contain confidential or proprietary information.

Invalid Crypto Error
Hello All,
I have to use GPG for windows.For that i have installed GPG4Win in my system
and try to use it through C++ code using DLL libgpgme-glib-11.
Getting "Invalid crytpto Engine" while calling "gpgme_engine_check_version".
Plz find the code snippet::
void _stdcall LoadGPG()
{
gpgme_error_t error;
char* p;
gpgme_key_t recipients[2] = {NULL, NULL};
gpgme_data_t clear_text, encrypted_text;
gpgme_encrypt_result_t result;
gpgme_engine_info_t info;
gpgme_keylist_mode_t keymode;
gpgme_protocol_t proto;
/* Initialize the locale environment. */
setlocale(LC_ALL, "");
int n =gpgme_set_global_flag("disable-gpgconf","1");
n = gpgme_set_global_flag("bindir","C://Program Files (x86)GNUGnuPG");
p = (char *) gpgme_check_version (NULL);//to initialize gpg
gpgme_set_locale (NULL, LC_CTYPE, setlocale (LC_CTYPE, NULL));
#ifdef LC_MESSAGES
gpgme_set_locale (NULL, LC_MESSAGES, setlocale (LC_MESSAGES, NULL));
#endif
gpgme_ctx_t *context = (gpgme_ctx_t *)malloc(sizeof *context);
error = gpgme_new(context);
error = gpgme_set_protocol (*context, GPGME_PROTOCOL_OpenPGP);
keymode = gpgme_get_keylist_mode(*context);
info = gpgme_ctx_get_engine_info(*context);
/* Setting the output type must be done at the beginning */
gpgme_set_armor(*context, 1);
error = gpgme_engine_check_version(GPGME_PROTOCOL_OpenPGP);
pEngineinfoerror1 = gpgme_strerror(error) ;
gpgme_data_t data;
gpgme_data_t cipher;
gpgme_error_t e = gpgme_data_new();
e = gpgme_data_new();
gpgme_data_set_file_name(data, "C:\\Logs\\test.txt");
error= gpgme_op_encrypt(*context,0,(gpgme_encrypt_flags_t)0,data,cipher);
pEngineinfoerror1 = gpgme_strerror(error) ;
}
Please let me know the solution for it ASAP.
Thanks & Regards
