virtual const achar* GetHashType ( ) const

pure virtual

Get the hash type. {Property}.

virtual tU32 GetDigestSize ( ) const

pure virtual

Get the digest size. {Property}.

virtual tBool Restart ( )

pure virtual

Ends the calculation of the current digest and reset the states for a new calculation.

virtual tBool Update	(	iFile *	apFile,
		tI64	aSize
	)

pure virtual

Adds data to the hash calculation, from the current file position for size bytes.

virtual tBool UpdateBlock	(	iFile *	apFile,
		tI64	aStart,
		tI64	aSize
	)

pure virtual

Adds data to the hash calculation, specifing a data range.

virtual tBool UpdateRaw	(	tPtr	apData,
		tSize	aSize
	)

pure virtual

Adds raw data to the hash calculation. {NoAutomation}.

virtual cString FinalString ( eRawToStringEncoding aEncoding )

pure virtual

Ends the calculation of the current digest, return the digest as a string.

Remarks: After final is called new calls to Update can be made to compute a new hash.

virtual tSize FinalFile ( iFile * apOutput )

pure virtual

Ends the calculation of the current digest, put the digest in the specified file.

Remarks: After final is called new calls to Update can be made to compute a new hash.

virtual tSize FinalRaw	(	tPtr	apData,
		tSize	anSize
	)

pure virtual

Ends the calculation of the current digest, put the digest in the specified raw memory.

Remarks: After final is called new calls to Update can be made to compute a new hash.
