Struct CShake256 

pub struct CShake256 { /* private fields */ }

cSHAKE256 hasher.

Implementations

impl CShake256

pub fn new_with_function_name( function_name: &[u8], customization: &[u8], ) -> Self

Creates a new cSHAKE instance with the given function name and customization.

Note that the function name is intended for use by NIST and should only be set to values defined by NIST. You probably don’t need to use this function.
