各位高手，谁有DES 、3DES及以此为基础的 ANSI X9.8、ANSI X 9.9的算法介绍????

Answer 1

是不是这样的呀？
BOOL DesEncrypt(LPCTSTR szKey, LPBYTE lpbySrc, LPBYTE lpbyDest, int iLength)
{
BYTE byKey[16] = {0};
CHAR szTempKey[24];
strcpy(szTempKey, szKey);
make3key(szTempKey, byKey); des3key(byKey, EN0);
for (int i = 0; i < iLength; i += 16)
D3des(lpbySrc + i, lpbyDest + i); return TRUE;
}BOOL DesDecrypt(LPCTSTR szKey, LPBYTE lpbySrc, LPBYTE lpbyDest, int iLength)
{
BYTE byKey[16] = {0};
CHAR szTempKey[24];
strcpy(szTempKey, szKey);
make3key(szTempKey, byKey); des3key(byKey, DE1);
for (int i = 0; i < iLength; i += 16)
D3des(lpbySrc + i, lpbyDest + i); return TRUE;
}

Answer 2

DES的话，有一本＜应用密码学＞
