Struct Feistel

Source 
pub struct Feistel<B>
where
    B: BuildHasher,
{ /* private fields */ }
Expand description

A basic Feistel Network cipher.

The cipher requires a series of hashes which are built using a supplied std::hash::BuildHasher (passed with the parameter name bob, coz it’z a builder, right?)
