VC turn C, to encrypt data decryption, Chinese is a question mark, and Numbers in English is normal-CodePudding

//make key 
Memset (key_des, 0, 9); 
Sprintf (temp (char *), "% s", W2A (keystring)); 
If (len_keystring & gt;=iSize) 
Memcpy (key_des, temp, iSize); 
The else 
Memcpy (key_des, temp, len_keystring); 

Sprintf (temp (char *), "% s", W2A (content)); 
Memset (tempout, 0409, 6); 
For (I=0, j=0; Len_instring & gt; 0; Len_instring -=iSize * 2, I +=iSize * 2, j +=iSize) 
{
HstrToChr (unsigned char (*) (temp + I), iSize * 2, res); 
Crypt_decrypt (je, res, key_des, des); 
Des [8]='\ 0'; 
Memcpy (tempout + j, des, iSize); 
} 

* outstring=A2BSTR (tempout (char *));

Method parameters (BSTR mark, BSTR in BSTR keystring, BSTR * outstring) keystring is the key content is the data
After I modified into c + + (QT), the content and keystring is a QString

//make key 


Memset (key_des, 0, 9); 

Char * ch_keystring; 
QByteArray ba_in_keystring=keystring. ToLatin1 (); 
Ch_keystring=ba_keystring. Data (); 


Char * ch_content; 
QByteArray ba_content=content. toLatin1 (); 
Ch_content=ba_in. Data (); 

Sprintf (temp (char *), "% s", ch_keystring); 

If (len_keystring & gt;=iSize) 
Memcpy (key_des, temp, iSize); 
The else 
Memcpy (key_des, temp, len_keystring); 


Sprintf (temp (char *), "% s", ch_content); 

Memset (tempout, 0409, 6); 

For (I=0, j=0; Len_instring & gt; 0; Len_instring -=iSize * 2, I +=iSize * 2, j +=iSize)

For the question mark in Chinese, English and digital normal

Excuse me, what's the problem?

CodePudding user response:

If the character encoding output window can print Chinese characters,

Print each char 0 xff16 into system, contrast
