Description

This is the context structure used in calculating SHA-256. Its size is 108 bytes. Initialize it using the MATH_SHA256Init function, provide the input data with the MATH_SHA256Update function, and get the message digest value with the MATH_SHA256GetHash function. SHA-256 is an algorithm to find the message digest value. For details, refer to the Federal Information Processing Standard, FIPS PUB 180-2.
