Extendable-output function is a variant of the cryptographic hash that allows its output to be arbitrarily long. In particular, the nature of the sponge construction makes a sponge hash a natural XOF (the regular hash functions with a fixed-size result are obtained from a sponge mechanism by stopping the squeezing phase after obtaining the fixed number of bits).[1]
