Hello,
This is my first message to an e-mail list ever. I don't even know if this is
the right e-mail list for me, please forgive me if I'm wrong, but unfortunately
I didn't found a GPGME e-mail list.
Currently I'm trying to use GPGME in my C++ application with GnuPG for
key-management and encryption. Sadly I'm not able to create a new key, because
my code hangs at gpgme_op_genkey. I have gpg 1.4.18 and gpg2 2.0.26 and GPGME
1.5.1 on my 64 bit Debian VM system (version Jesse) available. This is how I
initialize the library:
gpgme_engine_info_t info;
gpgme_error_t error;
const char * CONFIG_DIR = "/";
// Initializes gpgme
gpgme_check_version(NULL);
// Initialize the locale environment.
setlocale(LC_ALL, "");
gpgme_set_locale(NULL, LC_CTYPE, setlocale(LC_CTYPE, NULL));
#ifdef LC_MESSAGES
gpgme_set_locale(NULL, LC_MESSAGES, setlocale(LC_MESSAGES, NULL));
#endif
error = gpgme_set_engine_info(GPGME_PROTOCOL_OpenPGP, NULL,
CONFIG_DIR);
if(error)
return false;
error = gpgme_new(&mContext);
if(error)
return false;
// Check OpenPGP
error = gpgme_engine_check_version(GPGME_PROTOCOL_OpenPGP);
if(error)
return false;
// load engine info
error = gpgme_get_engine_info(&info);
if(error)
return false;
while(info && info->protocol != gpgme_get_protocol(mContext)) {
info = info->next;
}
// set path to our config file
error = gpgme_ctx_set_engine_info(mContext, GPGME_PROTOCOL_OpenPGP, NULL,
CONFIG_DIR);
if(error)
return false;
-----------------------------------------------------------------------------------------------------------------------------
Here I try to create the key:
std::string def = "<GnupgKeyParms format=\"internal\"> \n"
" Key-Type: default \n"
" Subkey-Type: default \n"
" Name-Real: Joe Tester3 \n"
" Name-Comment: with stupid passphrase \n"
" Name-Email: j...@foo.bar \n"
" Expire-Date: 0 \n"
" Passphrase: abc \n"
" </GnupgKeyParms> \n";
gpgme_error_t error = gpgme_op_genkey(mContext, def.c_str(), NULL,
NULL);
if(GPG_ERR_INV_VALUE == gpgme_err_code(error)){
std::cout << "Value error";
}
if(GPG_ERR_NOT_SUPPORTED == gpgme_err_code(error)){
std::cout << "Not supported error";
}
if(GPG_ERR_GENERAL == gpgme_err_code(error)){
std::cout << "general error";
}
if(error == gpgme_err_code(GPG_ERR_NO_ERROR)){
gpgme_genkey_result_t res = gpgme_op_genkey_result(mContext);
if(res->primary && res->sub){
result = true;
}
}
There is no error while initialising the library, so I don't know why it stops
at gpgme_op_genkey. Maybe GnuPG is trying to collect entropie? If I generate a
key using the GnuPG command line it tooks a very long time to collect entropie.
But after ~15 minutes the key generation completes successfully (I didn't
noticed that my program finished so far, even after 15 minutes+). I already
tried to remove the \n in each line, but I received a general error in this
case. Am I doing something wrong? Any help or hint is highly appreciated.
Best regards,
Sandra
