示例1: while
byte *encrypt( byte *dataIn , int len ) {
unsigned int memsize = ((len/8)+1)*8; // round to the upper 8 byte size
unsigned int nBlocks = ((len/8)+1); // Number of blocks. There is at least one block
unsigned int boffset = 0; // Byte offset
// WARNING WARNING WARNING WARNING
byte *bout = (byte *)malloc(memsize); // THIS IS a very bad idea!!!! Just for testing. Allocation should be done OUTSIDE the function.
while ( nBlocks > 0 ) {
des.tripleEncrypt(&bout[boffset], &dataIn[boffset], key);
boffset = boffset + 8;
nBlocks = nBlocks - 1;
};
return bout;
}示例2: tdesTest
void tdesTest()
{
byte out[8];
byte in[] = { 1, 2, 3, 4, 5, 6, 7, 8 };
byte key[] = {
0x3b, 0x38, 0x98, 0x37, 0x15, 0x20, 0xf7, 0x5e, // key A

0x3b, 0x38, 0x98, 0x37, 0x15, 0x20, 0xf7, 0x5e, // key C (in this case A)
