QCA cannot import an OpenPGP private key - it turns into public key

Question

Using QCA (libqca.so) OpenPGP library, I try to read a Private Key into a QCA::PGPKey object, but it appears QCA transforms it into the Public Key. The keypair is in keyring but QCA does not recognize it too.

Here are the codes:

   #include <QCoreApplication>

int main(int argc, char *argv[])

QCoreApplication a(argc, argv);

QCA::Initializer init;
if(!QCA::isSupported("openpgp")){
    throw std::exception();
}

QFile file("file.txt");
if(!file.open(QFile::WriteOnly | QFile::Text))
    throw std::exception();
QTextStream stream(&file);

QFile pubkey("slclientpub.asc");
if(!pubkey.open(QFile::ReadOnly | QFile::Text))
    throw std::exception();

QString pubkey_str = pubkey.readAll();
stream << "pubkey_str:\n"<< pubkey_str;

pubkey.flush();
pubkey.close();

QFile prikey("slclientsecret.asc");
if(!prikey.open(QFile::ReadOnly | QFile::Text))
    throw std::exception();

QString prikey_str = prikey.readAll();
stream << "prikey_str:\n"<< prikey_str;

prikey.flush();
prikey.close();

QCA::ConvertResult cr1, cr2;
QCA::PGPKey public_key_1 = QCA::PGPKey::fromString(pubkey_str,&cr1);
QCA::PGPKey private_key_2 = QCA::PGPKey::fromString(pubkey_str,&cr2);
QCA::PGPKey public_key_3("slclientpub.asc");
QCA::PGPKey private_key_4("slclientsecret.asc");


if((cr1 != QCA::ConvertGood) || (cr2 != QCA::ConvertGood)){
    throw std::exception();
}

stream<<"public_key_1 data:\n"
     <<"Secret: " << public_key_1.isSecret()
    <<"\nIn Keyring: " << public_key_1.inKeyring()
   <<"\n Data: \n"<<public_key_1.toString();

stream<<"private_key_2 data:\n"
     <<"Secret: " << private_key_2.isSecret()
    <<"\nIn Keyring: " << private_key_2.inKeyring()
   <<"\n Data: \n"<<private_key_2.toString();

stream<<"public_key_3 data:\n"
     <<"Secret: " << public_key_3.isSecret()
    <<"\nIn Keyring: " << public_key_3.inKeyring()
   <<"\n Data: \n"<<public_key_3.toString();

stream<<"private_key_4 data:\n"
     <<"Secret: " << private_key_4.isSecret()
    <<"\nIn Keyring: " << private_key_4.inKeyring()
   <<"\n Data: \n"<<private_key_4.toString();

stream.flush();
file.flush();
file.close();

return a.exec();
}

Why does your question start with "friends"? What does that mean? And there's no need to write "thanks in advance", in fact, it's explicitly discouraged. Please edit your post and remove all salutations and "thanks" from it. — sashoalm, Mar 22 '14 at 14:29
Great, and I've removed my downvote. Thanks for showing willingness to improve your question! But can you do one more thing - edit your question to indent the code properly? Right now it's not indented at all. By the way - did you right it in notepad? Most editors and IDEs will indent it automatically for you, so I was wondering. — sashoalm, Mar 23 '14 at 10:41
Yes, I can. I had to space line by line when I copied into Stack Overflow, I didn't know how to do in a better way. I'll try to do it today. — user3000075, Mar 24 '14 at 19:51
