Member Function Documentation

virtual OFCondition SiMAC::digest (  const unsigned char *  data,
unsigned long  length
)  [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.

virtual const char* SiMAC::getDefinedTerm (   )  const [pure virtual]
 

returns the DICOM identifier for this MAC algorithm

Returns:
DICOM defined term for algorithm

Implemented in SiMD5, SiRIPEMD160, and SiSHA1.

virtual unsigned long SiMAC::getSize (   )  const [pure virtual]
 

returns the size of a MAC in bytes.

Returns:
block size for this MAC algorithm

Implemented in SiMD5, SiRIPEMD160, and SiSHA1.

virtual OFCondition SiMAC::initialize (   )  [pure virtual]
 

initializes the MAC algorithm.

Returns:
status code

Implemented in SiMD5, SiRIPEMD160, and SiSHA1.

virtual E_MACType SiMAC::macType (   )  const [pure virtual]
 

returns the type of MAC algorithm computed by this object

Returns:
type of MAC algorithm

Implemented in SiMD5, SiRIPEMD160, and SiSHA1.
