Struct TupleHash

pub struct TupleHash<X> { /* private fields */ }

A cryptographic hash over a set of strings such that each string is unambiguously encoded.

For example, the TupleHash of ("abc", "d") will produce a different hash value than the TupleHash of ("ab", "cd").

For the XOF variant, see TupleHashXof.

Warning

TupleHash is only defined for cSHAKE128 and cSHAKE256. Using this with a different XOF might have worse security properties.

Implementations

impl<X: Xof> TupleHash<X>

pub fn new(s: &[u8]) -> Self

Creates a TupleHash with the customization string s.

pub fn update(&mut self, s: &[u8])

Writes the string s to the hash.

pub fn finalize_into(self, out: &mut [u8])

Returns a fixed-size output.

pub fn finalize<N: ArrayLength>(self) -> GenericArray<u8, N>

Returns a fixed-size output.
