不可逆加密演算法視頻

㈠ 不可逆的加密演算法

原型：
int WINAPI icePub_getMD5FromString(char *strData,char *strResult)
輸入：strData 待處理的文本串
輸出：strResult MD5結果串，32位元組
返回碼:

char buff[1024];
char buff2[1024];

strcpy(buff2,"Walk At Familiar Alley, Pursue Concordand's Footfall, Between Front And Back, What Course To Follow?");

typedef int (WINAPI ICEPUB_GETMD5FROMSTRING)(char *strData,char *strResult);
ICEPUB_GETMD5FROMSTRING *icePub_getMD5FromString = 0;
HINSTANCE hDLLDrv = LoadLibrary("icePubDll.dll");
if(hDLLDrv)
{
icePub_getMD5FromString=(ICEPUB_GETMD5FROMSTRING *)GetProcAddress(hDLLDrv,"icePub_getMD5FromString");
}
if(icePub_getMD5FromString)
icePub_getMD5FromString(buff2,buff);
if(hDLLDrv)
FreeLibrary(hDLLDrv);

AfxMessageBox(buff);

原型：
int WINAPI icePub_getMD5FromFile(char *strFilePath,char *strResult)
輸入：strFilePath 待MD5的文件名
輸出：strResult MD5結果串，32位元組
返回碼:

char buff[1024];

typedef int (WINAPI ICEPUB_GETMD5FROMFILE)(char *strFilePath,char *strResult);
ICEPUB_DESDECRYPTIONSTRING *icePub_getMD5FromFile = 0;
HINSTANCE hDLLDrv = LoadLibrary("icePubDll.dll");
if(hDLLDrv)
{
icePub_getMD5FromFile=(ICEPUB_DESDECRYPTIONSTRING *)GetProcAddress(hDLLDrv,"icePub_getMD5FromFile");
}
if(icePub_getMD5FromFile)
icePub_getMD5FromFile("D:\\icePubDLL.dll",buff);
if(hDLLDrv)
FreeLibrary(hDLLDrv);

AfxMessageBox(buff);

原型：
int WINAPI icePub_sha1FromString(char *strData,char *strResult)
輸入：strData 待處理的文本串
輸出：strResult SHA1結果串，40位元組
返回碼:

char buff[1024];
char buff2[1024];

strcpy(buff2,"Kiss Years's Scar, Strangeness Far Snivel, Between Hart And Head, Cloud And Mist Come And Go.");

typedef int (WINAPI ICEPUB_SHA1ROMSTRING)(char *strData,char *strResult);
ICEPUB_SHA1ROMSTRING *icePub_sha1FromString = 0;
HINSTANCE hDLLDrv = LoadLibrary("icePubDll.dll");
if(hDLLDrv)
{
icePub_sha1FromString=(ICEPUB_SHA1ROMSTRING *)GetProcAddress(hDLLDrv,"icePub_sha1FromString");
}
if(icePub_sha1FromString)
icePub_sha1FromString(buff2,buff);
if(hDLLDrv)
FreeLibrary(hDLLDrv);

AfxMessageBox(buff);

㈡ 目前常用的加密方法有

目前常用的加密方法有什麼帶旅如下：
1、不可逆加密演算法有MD5，HMAC，SHA1、SHA-224、SHA-256、SHA-384，和SHA-512，其中SHA-224、SHA-256、SHA-384，和SHA-512我們可以統稱為SHA2加密演算法，SHA加密算拿行滾法的安全性要比MD5更高，而SHA2加密演算法比SHA1的要高。
2、其中SHA後面的數字表示的是加密後的字元消余串長度，SHA1默認會產生一個160位的信息摘要。
