[SOLVED] QCA encode/decode crash
-
Hi everyone!
In my project i'm using QCA library to encode/decode datas by AES256. I have class which open file and do encode datas. This class look like:
#ifndef MDLFILEREADER_H #define MDLFILEREADER_H #include <QtCore> class MdlFileReader : public QObject { Q_OBJECT private: QString m_logFilePath; QString m_aesKey; QString m_aesIv; QString decode(QString encodeString, QString key, QString iv); QByteArray uncompressDatas(QByteArray datas); public: explicit MdlFileReader(QString path, QString key, QString iv, QObject *parent = 0); signals: void fileReaderDidFinish(QVariant jsonObj); void fileReaderDidUncompressContent(QString uncompressedString); public slots: void startParseFile(); }; #endif // MDLFILEREADER_HImplementation of class:
#include "mdlfilereader.h" #include <zlib.h> #include <QtCrypto> #define GZIP_WINDOWS_BIT 15 + 16 #define GZIP_CHUNK_SIZE 32 * 1024 QString MdlFileReader::decode(QString encodeString, QString key, QString iv) { if(!encodeString.isEmpty()) { QCA::Initializer init = QCA::Initializer(); QCA::SymmetricKey keyData = QCA::SymmetricKey(key.toUtf8()); QCA::InitializationVector ivData = QCA::InitializationVector(iv.toUtf8()); QCA::Cipher cipherRes = QCA::Cipher(QString("aes256"), QCA::Cipher::CBC, QCA::Cipher::DefaultPadding, QCA::Decode, keyData, ivData); QCA::SecureArray decryptedData = cipherRes.process(QCA::hexToArray(encodeString)); if (!cipherRes.ok()) { qDebug() << "Decryption failed ! "; return ""; } return QString(decryptedData.data()); } return ""; } QByteArray MdlFileReader::uncompressDatas(QByteArray datas) { QByteArray res; res.clear(); if(!datas.isEmpty()) { z_stream strm; strm.zalloc = Z_NULL; strm.zfree = Z_NULL; strm.opaque = Z_NULL; strm.avail_in = 0; strm.next_in = Z_NULL; int ret = inflateInit2(&strm, GZIP_WINDOWS_BIT); if (ret != Z_OK) { return QByteArray(); } char *input_data = datas.data(); int input_data_left = datas.length(); do{ int chunk_size = qMin(GZIP_CHUNK_SIZE, input_data_left); if(chunk_size <= 0) { break; } strm.next_in = (unsigned char*)input_data; strm.avail_in = chunk_size; input_data += chunk_size; input_data_left -= chunk_size; do { char out[GZIP_CHUNK_SIZE]; strm.next_out = (unsigned char*)out; strm.avail_out = GZIP_CHUNK_SIZE; ret = inflate(&strm, Z_NO_FLUSH); switch (ret) { case Z_NEED_DICT: ret = Z_DATA_ERROR;

}while (ret != Z_STREAM_END); inflateEnd(&strm); return res; } return res; } MdlFileReader::MdlFileReader(QString path, QString key, QString iv, QObject *parent) : QObject(parent) { m_logFilePath = path; m_aesKey = key; m_aesIv = iv; } void MdlFileReader::startParseFile() { if(!m_logFilePath.isEmpty()) { m_logFilePath = m_logFilePath.replace("file://", ""); QFile file(m_logFilePath); if(file.exists()) { if(file.open(QIODevice::ReadOnly | QIODevice::Text)) { QTextStream stream(&file); QString content = stream.readAll(); if(!content.isNull()) { QByteArray compressedDatas = QByteArray::fromBase64(content.toUtf8()); QString fileContent = QString(uncompressDatas(compressedDatas)); //Trying to decompress source datas emit fileReaderDidUncompressContent(fileContent); QString decodedString; if(!fileContent.isEmpty()) //If source datas was compressed. { decodedString = decode(fileContent, m_aesKey, m_aesIv); } else //If source datas doen't compressed we trying to decode withot decompress. { decodedString = decode(compressedDatas, m_aesKey, m_aesIv);

jsonObj["loggerInfo"] = loggerInfo; emit fileReaderDidFinish(jsonObj); } } } } } } } emit fileReaderDidFinish(QVariant()); }I use it like:
MdlFileReader* fileReader = new MdlFileReader(file, m_settingsManager->getAesKey(), m_settingsManager->getAesInventoryKey()); fileReader->setParent(this); connect(fileReader, &MdlFileReader::fileReaderDidFinish, this, [this](QVariant jsonObj) { if(!jsonObj.isNull()) { m_parser->updateFromJSONObject(jsonObj); } }); fileReader->startParseFile();I receive crash:
