SHA256 PHP Cantidad Caracteres

//Me interesó cuán "largo" es cada hash, así que lo hice:

//Descripción ¶
//hash(string $algo, string $data, bool $raw_output = false): string
  
//Parámetros ¶
//algo
//Nombre del algoritmo hash seleccionado (es decir, "md5", "sha256", "haval160,4", etc..). Para una lista de los algoritmos soportados véase hash_algos().
//data
//Mensaje a ser procesado.
//raw_output
//Cuando se establece en true la salida serán datos binarios sin formato, false la salida serán dígitos hexadecimales en minúsculas.

<?php
  $data = "hello";

  foreach (hash_algos() as $v) {
    $r = hash($v, $data, false);
    printf("%-12s %3d %s\n", $v, strlen($r), $r);
  }
?>

//Resultado (se recortan hashes largos)
