Util::IniFileConfiguration of an ecrypted stream (Crypto::CryptoInputStream) using wrong password, hangs

[omerbrandis]

Hello

I'm using poco version 1.12.3.

problem description :
i've followed this link the encryption/decryption functions.
i'm using Util::IniFileConfiguration to read an ecrypted file using Crypto::CryptoInputStream.
and as long as I'm providing the correct password and salt to the Crypto::CipherKey ctor, all is well.

but I am unable to handle the case of wrong password/salt,
the application hangs when trying the read from the undecryptable stream :

here's the code
std::string password = "";
std::string salt = "";

try {
// create crypto engine
Poco::Crypto::CipherFactory & factory = Poco::Crypto::CipherFactory::defaultFactory();
Poco::Crypto::CipherKey CK("aes-256-cbc", password, salt);
std::cout << "after create cipher key" << std::endl;
Poco::Crypto::Cipher * pCipher = factory.createCipher(CK);

// create a decryption stream
Poco::FileInputStream sink("RunParameters.encrypted");
Poco::Crypto::CryptoInputStream DecryptorStream(sink, pCipher->createDecryptor());
std::cout << "after create decryptor stream" << std::endl;

// read from the stream
Poco::AutoPtrPoco::Util::IniFileConfiguration pServerConfig(new Poco::Util::IniFileConfiguration(DecryptorStream));
std::cout << "after creating IniFileConfiguration object using the decryption stream" << std::endl;
}
catch (const Poco::Exception & Except)
{
ES.Message = "was not able to reach encrypted configuration file, exception = " + Except.displayText();
ES.Code = 8;
return(ES);
}

when I execute, it simply hangs. exception is not thrown.
last row in the terminal is "after create decryptor stream"

please advise,
:-)
