Struct b2sum_rust::Blake2bSum

pub struct Blake2bSum { /* fields omitted */ }

Blake2b File Hash Constructor

This is the official constructor used to call the new() function with the parameter of the intended digest size.

Example

use b2sum_rust::Blake2bSum;
 
fn main(){
    // Creates a new File Instance
    let context = Blake2bSum::new(64);
     
    // Outputs a Hexadecimal String
    let hash = context.read("example_file.txt");
 
    // Converts the hexadecimal string to a vector of bytes
    let _bytes = Blake2bSum::to_bytes(&hash);
 
    // Prints The Hexadecimal Representation
    println!("Hash: {}",hash);
 
    // Asserts That These Are Equal
    assert_eq!(hash,"33B20D15383F97EB46D4FA69442596170CCA01008963A7D0E47210C33AEEF991C78323850C012550C227954A40B3D7AD612568ABC73DB9233FAB9EA4F002B0CB");
}
 

Methods

impl Blake2bSum

pub fn new(digest: usize) -> Self

pub fn read<T: AsRef<Path>>(&self, path: T) -> String

Hash File

This is a function that hashes a file using Blake2b and returns the Hexadecimal Representation of it as a String. It takes as input any reference to Path.

It should be noted that changes to the file during hashing, such as truncating the file can cause problems.

pub fn to_bytes(s: &str) -> Vec<u8>
