Parameters
digestBitsize |
The size of output digest in bits. Should be positive multiple of 8 integer. |
Description
Each of these functions returns a pointer to a method-defined implementation of a particular hash algorithm. Use these functions in calls to HashInit and HashMessage. See table HashMethod Functions for an explanation of the values returned by the HashMethod functions.
Return Values
const ippsHashMethod* |
Pointer to the particular hash method. |
NULL |
digestBitsize is not positive multiple of 8 integer. |
