It operates on a fixed number of bits ( b) – the width. The sponge construction then operates on a state of b = r + c bits. r is defined as the bitrate and c as the capacity ( Figure 1 ).

WebA sponge function is a cryptographic function that can “absorb” any number of bits and “squeeze” any number of bits, like a sponge. This is different from what we observed about MD5; while MD5 will only produce fixed-size outputs of 16 bytes, a sponge function can output 1 byte, 26 bytes, 5000 bytes or any number that you like.
