Detailed Description

a class implementing the hash function RIPEMD160

Member Function Documentation

digest()

virtual OFCondition SiRIPEMD160::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.

finalize()

virtual OFCondition SiRIPEMD160::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.

getDefinedTerm()

virtual const char* SiRIPEMD160::getDefinedTerm ( ) const

virtual

returns the DICOM identifier for this MAC algorithm

Returns

DICOM defined term for algorithm

Implements SiMAC.

getSize()

virtual unsigned long SiRIPEMD160::getSize ( ) const

virtual

returns the size of a MAC in bytes.

Returns

block size for this MAC algorithm

Implements SiMAC.

initialize()

virtual OFCondition SiRIPEMD160::initialize ( )

virtual

initializes the MAC algorithm.

Returns

status code

Implements SiMAC.

macType()

virtual E_MACType SiRIPEMD160::macType ( ) const

virtual

returns the type of MAC algorithm computed by this object

Returns

type of MAC algorithm

Implements SiMAC.
