I want to generate RSA Public and private to char*

[Cam Vi Luong]

I have seen example of Cryptopp, there is GenerateRSAKey function which generate a public and private key to file, but I want to generate it to memory. Thus I have change the source code from 

HexEncoder privFile(new FileSink(privFilename));

HexEncoder pubFile(new FileSink(pubFilename));

--->

HexEncoder privString(new StringSink(privResult));

HexEncoder pubString(new StringSink(pubResult));

Is there right? 

Then I use this pair of key to encrypt and decrypt a string but it fatal error 

My encrypt and decrypt code:

char* CRSAService::EncryptString(const char *pszPublicKey, char *pszSeeds, char *pszMessage)

{

char *pszResult;

RandomPool randPool;

randPool.IncorporateEntropy((byte *)pszSeeds, strlen(pszSeeds));

StringSource pubString(pszPublicKey, true, new HexDecoder);

RSAES_OAEP_SHA_Encryptor pub(pubString);

string szResult;

StringSource(pszMessage, true, new PK_EncryptorFilter(randPool, pub, new HexEncoder(new StringSink(szResult))));

pszResult = new char[szResult.size() + 1];

copy(szResult.begin(), szResult.end(), pszResult);

pszResult[szResult.size()] = '\0';

return pszResult;

}

char* CRSAService::DecryptString(const char *pszPrivateKey, char *pszCipherText)

{

char *pszResult;

StringSource privString(pszPrivateKey, true, new HexDecoder);

RSAES_OAEP_SHA_Decryptor priv(privString);

string szResult;

StringSource(pszCipherText, true, new HexDecoder(new PK_DecryptorFilter(GlobalRNG(), priv, new StringSink(szResult))));

pszResult = new char[szResult.size() + 1];

copy(szResult.begin(), szResult.end(), pszResult);

pszResult[szResult.size()] = '\0';

return pszResult;

}

Is there something wrong?
