Can someone help me how can I add AESX to Crypto++ library?

[Mehmet TUFEKCI]

Hi everyone!

Can someone help me how can I add AESX to Crypto++ library? I tried to use 
DES-XEX codes in des.cpp. I added aes.cpp like:

NAMESPACE_BEGIN(CryptoPP)

 

void AES_X::Base::UncheckedSetKey(const byte *key, unsigned int length, 

const NameValuePairs &)

{

   AssertValidKeyLength(length);

 

   if (!m_aes.get())

       m_aes.reset(new RijndaelEncryption);

 

   memcpy(m_x1, key + (IsForwardTransformation() ? 0 : 16), BLOCKSIZE);

   memcpy(m_x3, key + (IsForwardTransformation() ? 16 : 0), BLOCKSIZE);

 } 

 void AES_X::Base::ProcessAndXorBlock(const byte *inBlock, const byte 

*xorBlock, byte *outBlock) const

{

   xorbuf(outBlock, inBlock, m_x1, BLOCKSIZE);

   m_aes->ProcessAndXorBlock(outBlock, xorBlock, outBlock);

   xorbuf(outBlock, m_x3, BLOCKSIZE);

}

 

NAMESPACE_END

And aes.h is like:

NAMESPACE_BEGIN(CryptoPP)

 

struct AES_X_Info : public FixedBlockSize<16>, public FixedKeyLength<16>

{

    CRYPTOPP_CONSTEXPR static const char *StaticAlgorithmName() {return 

  "AES_X";}

};

 

 

class AES_X : public AES_X_Info, public BlockCipherDocumentation

{

 

   class CRYPTOPP_NO_VTABLE Base : public BlockCipherImpl<AES_X_Info>

{

 public:

    void UncheckedSetKey(const byte *userKey, unsigned int length, const 
NameValuePairs &params);

    void ProcessAndXorBlock(const byte *inBlock, const byte *xorBlock, byte 
*outBlock) const;

 

protected:

    FixedSizeSecBlock<byte, BLOCKSIZE> m_x1, m_x3;

    // VS2005 workaround: calling modules compiled with /clr gets 
unresolved external symbol DES::Base::ProcessAndXorBlock

    // if we use DES::Encryption here directly without value_ptr.

    value_ptr<RijndaelEncryption> m_aes;

};

 

 public:

  typedef BlockCipherFinal<ENCRYPTION, Base> Encryption;

   typedef BlockCipherFinal<DECRYPTION, Base> Decryption;

};

 

 

 typedef AES_X::Encryption AES_X_Encryption;

 typedef AES_X::Decryption AES_X_Decryption;

 

 

 DOCUMENTED_TYPEDEF(Rijndael, AES);

 

 typedef RijndaelEncryption AESEncryption;

 typedef RijndaelDecryption AESDecryption;

 

 NAMESPACE_END

If I put m_aes->ProcessAndXorBlock(outBlock, xorBlock, outBlock); in 
aes.cpp it gives segmentation fault. Please tell me where is my problem? 

Thanks in advance..
