Struct TupleHash

pub struct TupleHash { /* private fields */ }

The TupleHash hash functions defined in SP800-185.

TupleHash is designed to provide a generic, misuse-resistant way to combine a sequence of strings for hashing such that, for example, a TupleHash computed on the tuple ("abc" ,"d") will produce a different hash value than a TupleHash computed on the tuple ("ab","cd"), even though all the remaining input parameters are kept the same, and the two resulting concatenated strings, without string encoding, are identical.

Implementations

impl TupleHash

pub fn v128(custom_string: &[u8]) -> TupleHash

Creates new TupleHash hasher with a security level of 128 bits.

pub fn v256(custom_string: &[u8]) -> TupleHash

Creates new TupleHash hasher with a security level of 256 bits.

Trait Implementations
