(AutoIt) DSA Generate Key

Generates a DSA public/private key pair and saves to PEM and DER file formats (both encrypted and non-encrypted).

An encrypted DSA PEM looks like this:

-----BEGIN DSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,9DAFD5C4CD62A5D0

-----END DSA PRIVATE KEY-----
