title: Cracking hash knowing password length?
body: <p>I do know the password length is 24. </p>
  
  <p>I also do know the search space: lower case, upper case and digits.</p>
  
  <p>The combinations should be (26+26+10)^24 = 62^24, right?</p>
  
  <p>I've tried with hashcat to set the charset and the mask </p>
  
  <pre><code>-1 ?l?u?d filename_to_crack ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1 
  </code></pre>
  
  <p>but it won't start because of an integer overflow error due to a huge keyspace; I guess the mask is too large!</p>
  
  <p>Someone can suggest another solution? I was thinking maybe I could write a script that generate a file of random (24 length) strings and then using this to perform a dictionary attack.</p>
