|
pure virtual |
feeds data into the MAC algorithm
- Parameters
-
data | pointer to raw data to be fed into the MAC, must not be NULL |
length | number of bytes in raw data array |
- Returns
- status code
Implemented in SiMD5, SiRIPEMD160, and SiSHA1.
virtual OFCondition SiMAC::finalize |

unsigned char * |
result | ) |
|
|
pure virtual |
finalizes the MAC and writes it to the given output array, which must be at least getSize() bytes large.
After a call to finalize, the MAC algorithm must be initialized again, see initialize().
- Parameters
-
result | pointer to array of getSize() bytes into which the MAC is written |
- Returns
- status code
Implemented in SiMD5, SiRIPEMD160, and SiSHA1.
