// Package sha3 implements the SHA-3 fixed-output-length hash functions and
|
||||
// the SHAKE variable-output-length hash functions defined by FIPS-202.
|
||||
//
|
||||
// Both types of hash function use the "sponge" construction and the Keccak
|
||||
// permutation. For a detailed specification see http://keccak.noekeon.org/
|
||||
//
|
||||
// # Guidance
|
||||
//
|
||||
// If you aren't sure what function you need, use SHAKE256 with at least 64
|
||||
// bytes of output. The SHAKE instances are faster than the SHA3 instances;
|
||||
// the latter have to allocate memory to conform to the hash.Hash interface.
|
||||
//
|
||||
// If you need a secret-key MAC (message authentication code), prepend the
|
||||
// secret key to the input, hash with SHAKE256 and read at least 32 bytes of
|
||||
// output.
|
||||
//
|
||||
// # Security strengths
|
||||
//
|
||||
// The SHA3-x (x equals 224, 256, 384, or 512) functions have a security
|
||||
// strength against preimage attacks of x bits. 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
|
||||
// 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. This means, in particular, that SHA3-256 only has
|
||||
// 128-bit collision resistance, because its output length is 32 bytes.
