After adding crypto++ lib application is crashing....

[Bharth]

application crashes in seckey.h file(this is the crypto header file)
.....................................................................
seckey.h
...................
this is line its crashing

BlockCipherFinal(const byte *key, size_t length)
{this->SetKey(key, length);}

@Bharth So, you are not only adding this lib but using it already?

[Bharth]

yes,for encrypting text i used

Hi,

Then please post the stack trace.

this is for encrypting
......................................
std::string EncryptManager::encode(QString text)
{

CryptoPP::byte key[MAX_ENCRYPT_KEY_SIZE], iv[MAX_ENCRYPT_IV_SIZE];

for(int i = 0; i < MAX_ENCRYPT_KEY_SIZE; i++)
key[i] = mKey[i];

for(int i = 0; i < MAX_ENCRYPT_IV_SIZE; i++)
    iv[i] = DEFAULT_ENCRYPT_IV[i];

std::string plaintext = text.toStdString();
std::string ciphertext;

CryptoPP::AES::Encryption aesEncryption(key, MAX_ENCRYPT_KEY_SIZE);
CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption(aesEncryption, iv);

CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length());
stfEncryptor.MessageEnd();

return encode64(ciphertext);

}

this is for decrypting
.....................................
QString EncryptManager::decode(std::string text)
{
CryptoPP::byte key[MAX_ENCRYPT_KEY_SIZE], iv[MAX_ENCRYPT_IV_SIZE];

for(int i = 0; i < MAX_ENCRYPT_KEY_SIZE; i++)
    key[i] = mKey[i];

for(int i = 0; i < MAX_ENCRYPT_IV_SIZE; i++)

std::string encrypted_text = decode64(text);
std::string decryptedtext;

return QString(decryptedtext.c_str());

@Bharth You did not post stack trace.
Did you actually try to debug your app to see where EXACTLY it is crashing? This is first thing to do...

[Pablo J. Rogina]

@Bharth said in After adding crypto++ lib application is crashing....:

i built crypto700 lib and i added .a file to our Qt project and also headers if i run application is crashing....

In addition to provide the stack trace as asked before, are you using the same compiler to build the library and your Qt project?

[Bharth]

i used QT command prompt

[Bharth]

while building boost library i used windows command prompt,,,,and while building crypto++ library i have used qt command prompt

[jsulm]

@Bharth Please just say whether you used SAME compiler to build both...

[Pablo J. Rogina]

@Bharth said in After adding crypto++ lib application is crashing....:

while building boost library i used windows command prompt,,,,and while building crypto++ library i have used qt command prompt

Could it be possible you share the actual command/settings used for every build you did (Boost, libcrypto, Qt app)?

[Bharth]

@jsulm No different for boost i used windows and for cryptoo i used qt command prompt because in windows command prompt im not able to generate .a file

[Bharth]

@Pablo-J.-Rogina for boost build
............................................................
In command prompt
cd boost-1-68-0
boostrap.bat
b2 toolset=gcc

for crypto++
...................
cd crypto
mingw32-make CXXFLAGS="-DNDEBUG-g2-O3-std=c++11"

[Pablo J. Rogina]

@Bharth mmm no debug settings for Boost... I'm suspicious that you might be mixing release and debug version of the application and libraries.
