Crypto ++，_ BLOCK_TYPE_IS_VALID错误 [英] Crypto++, _BLOCK_TYPE_IS_VALID error

问题描述

我已经从其他网站复制了这段代码并且无法编译它;我是密码学的新手，虽然我尽力让这个工作，但我一直得到表达式：_BLOCK_TYPE_IS_VALID（pHead-> nBlockUse）我知道这个错误与堆有关但我没有执行任何操作删除这几行代码。

  #include     dll.h 
  < span class =code-keyword> #include     modes.h 
   #include     aes.h 
   #include  < span class =code-preprocessor>   filters.h 
   #include     iostream 
   #include     cryptlib.h 
  
 
  int  main（ int  argc ， char  * argv []）{
 
 
  //    
  //  密钥和IV设置 
  //    
 
字节键[CryptoPP :: AES :: DEFAULT_KEYLENGTH]，iv [CryptoPP :: AES :: BLOCKSIZE]; 
 memset（密钥，0x00，CryptoPP :: AES :: DEFAULT_KEYLENGTH）; 
 memset（iv，0x00，CryptoPP :: AES :: BLOCKSIZE）; 
 
 
  //    
  //  字符串和接收器设置 
  //    
 std :: string plaintext =  现在是所有好人来到助手的时候......; 
 string ciphertext; 
 std :: string decryptedtext; 
 
  //    
  //  转储纯文本 
  //    
 std :: cout<<  纯文本（<< plaintext.size（）<<   bytes）<<的std :: ENDL; 
 std :: cout<<纯文本; 
 std :: cout<< std :: endl<<的std :: ENDL; 
 
  //

  //    
 
 CryptoPP :: AES ::加密aesEncryption（密钥，CryptoPP :: AES :: DEFAULT_KEYLENGTH）;

 stfEncryptor.Put（reinterpret_cast< const  unsigned   char  *>（plaintext.c_str（） ），plaintext.length（）+  1 ）; 
 stfEncryptor.MessageEnd（）; 
 
 
 
 
 
  //    
  //  转储密文 
  //    
 std :: cout<<  密文（<< ciphertext.size（）<<   bytes）<<的std :: ENDL; 
 
  for （ unsigned   int  i =  0 ; i< ciphertext.size（）; i ++）{
 
 std :: cout<<   0x<< std :: hex<< （0xFF& static_cast< byte>（ciphertext [i]））<<  ; 
} 
 
 std :: cout<< std :: endl<<的std :: ENDL; 
 
  //    
  //  解密 
  //    
 
 CryptoPP :: AES ::解密aesDecryption（密钥，CryptoPP :: AES :: DEFAULT_KEYLENGTH）; 
 CryptoPP :: CBC_Mode_ExternalCipher ::解密cbcDecryption（aesDecryption，iv）; 
 
 CryptoPP :: StreamTransformationFilter * stfDecryptor =  new  CryptoPP :: StreamTransformationFilter（cbcDecryption， new  CryptoPP :: StringSink（decryptedtext））; 
 stfDecryptor-> Put（reinterpret_cast< const  unsigned   char  *>（ciphertext.c_str （）），ciphertext.size（））; 
 stfDecryptor-> MessageEnd（）; 
 
  //    
  //  转储解密文本 
  //    
 
 std :: cout<<  解密文本：<<的std :: ENDL; 
 std :: cout<< decryptedtext; 
 std :: cout<< std :: endl<<的std :: ENDL; 
 
 
 
  return   0 ; 
} 

值得一提的是，如果我评论这两行，我不会t得到堆错误

 stfEncryptor.Put（reinterpret_cast< const  unsigned   char  *>（plaintext.c_str（）），plaintext.length（）+  1 ）; 
 stfEncryptor.MessageEnd（）; 

我尝试调试它，错误在最后一次返回0之前弹出，我认为在调用类Destructor时，de-allocation导致了这个问题？





任何帮助都将不胜感激。

解决方案

我自己找到了解决方案;在编译CryptoPP的源代码时，在 解决方案属性 （cryptdll）中，在 C / C ++ 菜单下有一个名为<的子菜单b>代码生成，字段运行时库应该是多线程调试DLL（/ MDd）。谢谢你的时间。告别。

Hi, I have copied this piece of code from another site and have trouble compiling it; I'm new to cryptography and whilst I tried my best to get this to work, i keep getting "Expression: _BLOCK_TYPE_IS_VALID(pHead->nBlockUse)" I know this error has to do with the heap but I didn't perform any Delete in these few lines of code.

#include "dll.h" 
#include "modes.h"
#include "aes.h"
#include "filters.h"
#include "iostream"
#include "cryptlib.h"


int main(int argc, char* argv[]) {


    //
    // Key and IV setup
    //
	
    byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );


    //
    // String and Sink setup
    //
    std::string plaintext = "Now is the time for all good men to come to the aide...";
    string ciphertext;
    std::string decryptedtext;

    //
    // Dump Plain Text
    //
    std::cout << "Plain Text (" << plaintext.size() << " bytes)" <<    std::endl;
    std::cout << plaintext;
    std::cout << std::endl << std::endl;

    //
    // Create Cipher Text
    //
	
	CryptoPP::AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, iv );

    CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink(     ciphertext ) ); 
    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() + 1   );
    stfEncryptor.MessageEnd();


	

	
    //
    // Dump Cipher Text
    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( unsigned int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<byte>(ciphertext[i])) << " ";
    }

    std::cout << std::endl << std::endl;

    //
    // Decrypt
    //
    
	CryptoPP::AES::Decryption aesDecryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );

    CryptoPP::StreamTransformationFilter * stfDecryptor=new  CryptoPP::StreamTransformationFilter(cbcDecryption, new CryptoPP::StringSink( decryptedtext  ) );
    stfDecryptor->Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor->MessageEnd();

    //
    // Dump Decrypted Text
    //
	
    std::cout << "Decrypted Text: " << std::endl;
    std::cout << decryptedtext;
    std::cout << std::endl << std::endl;

	

    return 0;
}

While it is worth mentioning if I comment these two lines I don't get the heap error anymore

stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() + 1   );
    stfEncryptor.MessageEnd();

I did try to debug it, and the error pops right before the last return 0, I think while the class Destructor is being called the de-allocation is causing this issue?


Any help would be greatly appreciated.

解决方案

I found the solution myself; while compiling the source code of CryptoPP, in the solution properties(cryptdll), under C/C++ menu there is a sub-menu called Code Generation, the field Runtime Library should be Multi-threaded Debug DLL (/MDd). Thanks for your time guys. Farewell.
