Since they only produce "x" -// bits of output, their collision-resistance is only "x/2" bits. -// -// The SHAKE-256 and -128 functions have a generic security strength of 256 and -// 128 bits against all attacks, provided that at least 2x bits of their output -// is used. Requesting more than 64 or 32 bytes of output, respectively, does -// not increase the collision-resistance of the SHAKE functions. -// -// -// The sponge construction -// -// A sponge builds a pseudo-random function from a public pseudo-random -// permutation, by applying the permutation to a state of "rate + capacity" -// bytes, but hiding "capacity" of the bytes. -// -// A sponge starts out with a zero state. To hash an input using a sponge, up -// to "rate" bytes of the input are XORed into the sponge's state. The sponge -// is then "full" and the permutation is applied to "empty" it. This process is -// repeated until all the input has been "absorbed". The input is then padded. -// The digest is "squeezed" from the sponge in the same way, except that output -// output is copied out instead of input being XORed in. -// -// A sponge is parameterized by its generic security strength, which is equal -// to half its capacity; capacity + rate is equal to the permutation's width. -// Since the KeccakF-1600 permutation is 1600 bits (200 bytes) wide, this means -// that the security strength of a sponge instance is equal to (1600 - bitrate) / 2. -// -// -// Recommendations -// -// The SHAKE functions are recommended for most new uses. They can produce -// output of arbitrary length. SHAKE256, with an output length of at least -// 64 bytes, provides 256-bit security against all attacks. The Keccak team -// recommends it for most applications upgrading from SHA2-512. (NIST chose a -// much stronger, but much slower, sponge instance for SHA3-512.) -// -// The SHA-3 functions are "drop-in" replacements for the SHA-2 functions. -// They produce output of the same length, with the same security strengths -// against all attacks.
