title: Generate random bytes for gpg --gen-key
body: <p>I'm using putty to connect to a unix host where I want to generate a new gpg key.
  After the Key generation started I get this message </p>
  
  <pre><code>Not enough random bytes available.  Please do some other work to give
  the OS a chance to collect more entropy! (Need 292 more bytes)
  </code></pre>
  
  <p>This isn't the real problem.
  The real problem is now I cannot issue any more commands to the shell, it looks like this</p>
  
  <pre><code>dfjd
  q
  s
  w
  e
  r
  t
  z
  z
  u
  ^_
  ^[[A^[[A
  </code></pre>
  
  <p>Why is this the case, no command gets executed anymore and why does the arrow up key show up as ^[[A?
  How can I fix this and issue some commands that the key can get generated?</p>
