QCA无法导入OpenPGP私钥 - 它变成了公钥

Question

使用QCA（libqca.so）OpenPGP库，我尝试将私钥读入QCA :: PGPKey对象，但看起来QCA将其转换为公钥。 密钥对是密钥环，但QCA也不承认它。

以下是代码：

   #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();
}

file.txt的（OUTPUT）：
