They solve the symmetric crypto problem with simplicity and efficiency. However, none of them seem to achieve 256-bit security without relying on a gigantic state (such as Keyak). 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. how many carbohydrates in pears
