Computes the SHA-256 hash of an array of 32-bit words.

​
Signature

pub fn compute_sha256_u32_array(
    mut input: Array, last_input_word: u32, last_input_num_bytes: u32,
) -> [u32; 8]

​
Arguments

  • input - An array of u32 values to hash
  • last_input_word - The final word when input is not word-aligned
  • last_input_num_bytes - Number of bytes in the last input word (must be less than 4)

​
Returns

  • The SHA-256 hash of the input array + last_input_word as big endian

​
Examples

use core::sha256::compute_sha256_u32_array;

let hash = compute_sha256_u32_array(array![0x68656c6c], 0x6f, 1);
assert!(hash == [0x2cf24dba, 0x5fb0a30e, 0x26e83b2a, 0xc5b9e29e, 0x1b161e5c, 0x1fa7425e,
0x73043362, 0x938b9824]);
