可以根据NTL库进RSA加密、解密算法的实现

NTL_OPEN_NNS


void OpenWrite(NTL_SNS ofstream& s, const char *name);

// opens file for writing...aborts if fails

void OpenRead(NTL_SNS ifstream& s, const char *name);

// opens file for reading

char *FileName(const char* stem, const char *ext);

// builds the name "stem.ext"

char *FileName(const char* stem, const char *ext, long d);

// builds the name stem.ext.d
