Detailed Description
a class implementing the hash function MD5
Member Function Documentation
| virtual OFCondition SiMD5::digest | ( | const unsigned char * | data, |
| unsigned long | length | ||
| ) | [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
Implements SiMAC.
| virtual OFCondition SiMD5::finalize | ( | unsigned char * | result | ) | [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
Implements SiMAC.
| virtual const char* SiMD5::getDefinedTerm | ( | ) | const [virtual] |
returns the DICOM identifier for this MAC algorithm
- Returns:
- DICOM defined term for algorithm
Implements SiMAC.
| virtual unsigned long SiMD5::getSize | ( | ) | const [virtual] |
| virtual OFCondition SiMD5::initialize | ( | ) | [virtual] |
| virtual E_MACType SiMD5::macType | ( | ) | const [virtual] |
returns the type of MAC algorithm computed by this object
- Returns:
- type of MAC algorithm
Implements SiMAC.
