The cryptographic algorithm that takes an input string of any length and returns a string of any requested variable length is a sponge function. The sponge function is a subclass of SHA-3 (Secure Hash Algorithm 3) that is suitable for a wide range of applications including message authentication, digital signatures, and pseudo-random number generation. The sponge function has been designed to be extremely resistant to cryptanalysis and so is considered to be one of the most secure cryptographic algorithms currently available.
