Adding RSA benchmarking

Note

The OpenSSL library is better for security and performance, so we implemented a Qt wrapper library to make it easier to use. See the EasySSL library.

Fast encryption library supporting RSA and AES algorithms.

Futures

The Qt-Secret library supports the following algorithms:

RSA

The current implementation supports the following key sizes:

Supported sizes

RSA64
RSA128
RSA256
RSA512
RSA1024
RSA2048
RSA3072
RSA4096
RSA6144
RSA8192

Supported futures

Encryption and decryption of messages.
Signature and verification of the message signature.

AES

AES implementation was borrowed from bricke, because it fulfills the goals of this library.

Individual thanks bricke for implementing the AES encryption class.

AES Levels

The class supports all AES key lengths

AES_128
AES_192
AES_256

Modes

The class supports the following operating modes

ECB
CBC
CFB
OFB

Padding

By default the padding method is ISO, however, the class supports:

ZERO
PKCS7
ISO

Build

with qmake

git clone https://github.com/QuasarApp/Qt-Secret.git
cd Qt-Secret
git submodule update --init --recursive
sudo apt install qt5-default
qmake -r DEFINE+=WITHOUT_GUI Qt-Secret.pro

DEFINE+=WITHOUT_GUI fot build without gui example, if you want build gui example remove this line. For build the gui example you need to install qml controls 2 in you os. Try sudo apt install qml-module-qtquick-controls2 qtdeclarative5-dev qtdeclarative5-qtquick2-plugin

make -j8
make test #(for testing)

with cmake

git clone https://github.com/QuasarApp/Qt-Secret.git
cd Qt-Secret
git submodule update --init --recursive
sudo apt install qt5-default
cmake -DCMAKE_PREFIX_PATH=you/Qt/dir .
make -j8
make test #(for testing)

Include

for qmake projects

cd yourRepo
git submodule add https://github.com/QuasarApp/Qt-Secret.git # add the repository of Qt-Secret into your repo like submodule
git submodule update --init --recursive
Add to the list of libraries for the Qt-Secret assembly. For example, you can create Main.Pro in which connect Qt-Secret and your project.pro files as subprojects.

Main.pro:

TEMPLATE = subdirs
CONFIG += ordered

SUBDIRS += \
           Qt-Secret \
           MyProject

Include in your MyProject.pro file the pri file of Qt-Secret library

include($$PWD/../Qt-Secret/src/Qt-Secret.pri)

Rebuild your project

For cmake projects

cd yourRepo
git submodule add https://github.com/QuasarApp/Qt-Secret.git # add the repository of Qt-Secret into your repo like submodule
git submodule update --init --recursive
Include in your CMakeLists.txt file the main CMakeLists.txt file of Qt-Secret library

  add_subdirectory(Qt-Secret)
  target_link_libraries(MyBinary PUBLIC Qt-Secret)

Rebuild your project

Note

By Default Qt-Secret makes as a static library. If you want to create a shared library just add the BUILD_SHARED_LIBS into your main CMakeLists.txt file. Example :

set(BUILD_SHARED_LIBS ON)
add_subdirectory(Qt-Secret)
target_link_libraries(MyBinary PUBLIC Qt-Secret)

For other build systems

cd yourRepo
git submodule add https://github.com/QuasarApp/Qt-Secret.git # add the repository of Qt-Secret into your repo like submodule
git submodule update --init --recursive
Add the rule for build Qt-Secret
Add INCLUDEPATH and LIBS for your build system
Rebuild your project

Detailed instructions of include in QtCreator see here.

Usage

RSA

Encryption and decryption of messages.

#include <qrsaencryption.h>
#include <QDebug>

bool testEncryptAndDecryptExample() {

    QByteArray pub, priv;
    QRSAEncryption e(QRSAEncryption::Rsa::RSA_2048);
    e.generatePairKey(pub, priv); // or other rsa size

    QByteArray msg = "test message";

    auto encryptMessage = e.encode(msg, pub);

    if (encryptMessage == msg)
        return false;

    auto decodeMessage = e.decode(encryptMessage, priv);

    return decodeMessage == msg;
}

int main() {
    if (testEncryptAndDecryptExample()) {
        qInfo() << "Success!";
    }
}

Signature and verification of the message signature.

#include <qrsaencryption.h>
#include <QDebug>

bool testExample() {
    QByteArray pub, priv;
    QRSAEncryption e(QRSAEncryption::Rsa::RSA_2048);
    e.generatePairKey(pub, priv); // or other rsa size

    QByteArray msg = "test message";

    auto signedMessage = e.signMessage(msg, priv);

    if (e.checkSignMessage(signedMessage, pub)) {
        qInfo() <<" message signed success";
        return true;
    }

    return false;

}

int main() {
    if (testExample()) {
        qInfo() <<"success!";
    }
}

AES

Sample code using a 128bit key in ECB mode

#include "qaesencryption.h"

QAESEncryption encryption(QAESEncryption::AES_128, QAESEncryption::ECB);
QByteArray encodedText = encryption.encode(plainText, key);

QByteArray decodedText = encryption.decode(encodedText, key);

Example for 256bit CBC using QString

#include <QCryptographicHash>
#include "qaesencryption.h"

QAESEncryption encryption(QAESEncryption::AES_256, QAESEncryption::CBC);

QString inputStr("The Advanced Encryption Standard (AES), also known by its original name Rijndael "
                 "is a specification for the encryption of electronic data established by the U.S. "
                "National Institute of Standards and Technology (NIST) in 2001");
QString key("your-string-key");
QString iv("your-IV-vector");

QByteArray hashKey = QCryptographicHash::hash(key.toLocal8Bit(), QCryptographicHash::Sha256);
QByteArray hashIV = QCryptographicHash::hash(iv.toLocal8Bit(), QCryptographicHash::Md5);

QByteArray encodeText = encryption.encode(inputStr.toLocal8Bit(), hashKey, hashIV);
QByteArray decodeText = encryption.decode(encodeText, hashKey, hashIV);

QString decodedString = QString(encryption.removePadding(decodeText));

//decodedString == inputStr !!!

Example via static invocation

Static invocation without creating instances, 256 bit key, ECB mode, starting from QString text/key

#include <QCryptographicHash>
#include "qaesencryption.h"

QString inputStr("The Advanced Encryption Standard (AES), also known by its original name Rijndael "
                 "is a specification for the encryption of electronic data established by the U.S. "
                "National Institute of Standards and Technology (NIST) in 2001");
QString key("your-string-key");
QString iv("your-IV-vector");

QByteArray hashKey = QCryptographicHash::hash(key.toLocal8Bit(), QCryptographicHash::Sha256);
QByteArray hashIV = QCryptographicHash::hash(iv.toLocal8Bit(), QCryptographicHash::Md5);

//Static invocation
QByteArray encrypted = QAESEncryption::Crypt(QAESEncryption::AES_256, QAESEncryption::CBC, 
                        inputStr.toLocal8Bit(), hashKey, hashIV);
//...
// Removal of Padding via Static function
QString decodedString = QString(QAESEncryption::RemovePadding(decodeText));
