Hello,
I write a simple test code for WAKE_CFB Symmetric Encryption Algorithm, and if
the input file length
is not multiple of word size (4 byte), i got a segmentation fault signal.
-----------------------------------------------------------------------------------------------------
#include <cryptopp/files.h>
#include <cryptopp/filters.h>
#include <cryptopp/osrng.h>
#include <cryptopp/wake.h>
using namespace CryptoPP;
using namespace std;
int main()
{
� � try
� � {
� � � � AutoSeededRandomPool rng;
� � � � WAKE_CFB<>::Encryption encoder;
� � � � SecByteBlock sbbKey(encoder.DefaultKeyLength());
� � � � rng.GenerateBlock(sbbKey.begin(), sbbKey.size());
� � � � encoder.SetKey(sbbKey, sbbKey.size());
� � � � FileSource("sample.txt", true, new StreamTransformationFilter(encoder,
new FileSink("sample.dat")));
� � }
� � catch (const CryptoPP::Exception &e)
� � {
� � � � cout << "\nCryptoPP::Exception caught: " << e.what() << endl;
� � � � return 1;
� � }
� � catch (const std::exception &e)
� � {
� � � � cout << "\nstd::exception caught: " << e.what() << endl;
� � � � return 2;
� � }
� � return 0;
}
