title: Decrypt OpenSSL Bruteforce
body: <p>I forgot the password to my bitcoin backup and would like to brute-force decrypt it. 
  I have been given this information; 
  "The manual backup files are encrypted using your chosen backup password. You can use OpenSSL to            decrypt:</p>
  
  <pre><code>openssl enc -d -aes-256-cbc -a -in &lt;filename&gt;" 
  </code></pre>
  
  <p>Unfortunately, I don't have much experience doing this and all I can do it get it in terminal asking for the password. Can anybody give me instructions on how to brute-force decrypt a file using OpenSSL?</p>
  
  <p>n.b. The password was quite simple, using only letters and perhaps one number.</p>
