Function pbkdf2_identifier::identify_iterations

pub fn identify_iterations<T>(
    password: &[u8], 
    hash: &[u8], 
    salt: &[u8], 
    max: Option<usize>
) -> Option<usize> where
    T: Input + BlockInput + FixedOutput + Reset + Default + Clone,
    T::BlockSize: ArrayLength<u8>,
    T::OutputSize: ArrayLength<u8>, 

Tries to find the iteration count of the hash knowing its algorithm. password - The password of the hash hash - The hash itself salt - The salt used in the derivation max - The maximum number of iteration to try. Use 0 to try until aborted.
