Generate DSA SSH Key

Generates a DSA SSH key and saves to various public and private key file formats (OpenSSH and PuTTY). AutoIt

Local $bSuccess = False

; numBits should be a minimum of 1024 and
; a multiple of 64.  Typical values are
; 1024 or 2048.

; Note: Generating a public/private key pair is CPU intensive
; and may take a short amount of time (more than few seconds,
; but less than a minute).
