Try this out....
byte key[CryptoPP::AES::DEFAULT_KEYLENGTH];
byte iv[CryptoPP::AES::BLOCKSIZE];
memset(key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH);
memset(iv, 0x00, CryptoPP::AES::BLOCKSIZE);
AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
CBC_Mode_ExternalCipher::Encryption cbcEncryption(aesEncryption, iv);
string plaintext = "test";
string ciphertext;
string decryptedtext;
CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new
CryptoPP::StringSink( ciphertext ) );
stfEncryptor.Put( reinterpret_cast<const unsigned
char*>( plaintext.c_str() ), plaintext.length() + 1 );
stfEncryptor.MessageEnd();
CryptoPP::AES::Decryption aesDecryption(key,
CryptoPP::AES::DEFAULT_KEYLENGTH);
CryptoPP::CBC_Mode_ExternalCipher::Decryption
cbcDecryption( aesDecryption, iv );
CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new
CryptoPP::StringSink( decryptedtext ) );
stfDecryptor.Put( reinterpret_cast<const unsigned
char*>( ciphertext.c_str() ), ciphertext.size() );
try
{
stfDecryptor.MessageEnd();
}
catch(Exception ex)
{
Exception::ErrorType et = ex.GetErrorType();
}
It works on my system.
Thanks
