Struct TargetHashAndHashFunction 

pub struct TargetHashAndHashFunction<T: CrackTarget> { /* private fields */ }

Abstraction over a hashing algorithm and the target hash that needs to be cracked. T is of type CrackTarget. This generic struct exists so that hashes of type CrackTarget can be checked independent of the hashing algorithm. This is more efficient than transforming every hash to a string and compare the hash string representations afterwards.

Implementations

impl<T: CrackTarget> TargetHashAndHashFunction<T>

pub fn new( target_hash: TargetHashInput<'_>, hash_fn: fn(&str) -> T, hash_str_repr_to_hash_type_fn: fn(hash_as_string: &str) -> T, hash_type_to_str_repr_fn: fn(hash: &T) -> String, ) -> Self

Constructor that takes a hashing function and a target hash.

Parameters

• target_hash String representation of the target hash we want to crack. This is usually the hex string representation of a sha256 hash or so.
• hash_fn Transforms a plain input password/guess of type str to the target hash. This is the hashing function.
• hash_str_repr_to_hash_type_fn Function that can take the argument target_hash and transform it to the target hashing type. This usually transforms the hex string that represents the hash to bytes in memory.
• hash_type_to_str_repr_fn Function that transform the hash type to a string representation. Usually, this will return a hex string that represents the hash.

impl<T: CrackTarget> TargetHashAndHashFunction<T>

pub fn hash_str_repr_to_hash_type(&self, hash_as_string: &str) -> T

Transforms the (hex) string representation into the type the hash implementation uses to represent hashes.

pub fn hash(&self, input: &str) -> T

Hashes a value.

pub fn target_hash(&self) -> &T

Returns the target hash that we want to crack.

pub fn hash_type_to_str_repr(&self, hash: &T) -> String

Returns a (hex) string representation of the hash.

pub fn hash_matches(&self, input: &str) -> bool

Hashes the input value and returns if it equals the target hash. If so, the hash got cracked.
