Thank you for this encouraging words. In fact I got solved another problem.
It seems that the reason GnuPG was asking for the dummy password, was
that this user was set as a signer in my context (as default). Now I use
gpgme_signers_clear(mContext);
before I encrypt/sign my string. The request for the dummy password
disappeared. The only problem remaining is that the application still ignores
my
own password callback and uses the GnuPG default:
gpgme_set_passphrase_cb(mContext, passphrase_cb, nullptr);
I replaced my callback with your code:
gpgme_error_t passphrase_cb(void *hook, const char *uid_hint, const char
*passphrase_info,
int prev_was_bad, int fd){
std::string passphrase { "" };
size_t written { 0 };
std::cout << "Enter your passphrase: ";
std::getline(std::cin, passphrase);
if (passphrase.empty())
return GPG_ERR_CANCELED;
while (written < passphrase.size())
{
ssize_t bytesWritten = gpgme_io_write(fd,
&passphrase[0] + written,
passphrase.size() - written);
if (bytesWritten == 0)
break;
written += bytesWritten;
}
gpgme_io_write(fd, "\n", 1);
return GPG_ERR_NO_ERROR;
}
