MD4 API Overview
MD4 API assists you in generating MD4 message digests.
MD4 message digests can be generated in two modes: accumulative and non-accumulative.
The accumulative mode is applied when the data for which the digest is calculated (data) represents one or more continuous memory block(s) or when the data is created at runtime in many steps (for instance, when reading a file).
Non-accumulative mode can be applied when the data represents only one continuous memory block.
Note. When the data represents just one continuous memory block, both methods can be applied.
To generate the message digest in the accumulative mode, perform the following:
Allocate at least SLC_MD4_CONTEXTSIZE bytes for the context.
Call the SL_MD4_Update function for each continuous memory block of data to perform the calculations.
Note. Call the SL_MD4_FinalHex function when you need to retrieve the hexadecimal string representation of the message digest.
To generate the message digest in the non-accumulative mode, perform the following:
Note 1. Call the SL_MD4_CalculateHex function when you need to retrieve the hexadecimal string representation of the message digest.
