(AutoIt) Generate new DSA Key from OpenSSL Parameters FileGenerates a new DSA key from an OpenSSL-created parameters file (DER and PEM formats supported). Examples of using OpenSSL to create parameter files are shown here: openssl dsaparam -outform DER 1024 < seedData.txt >dsaparam.der openssl dsaparam 1024 < seedData.txt >dsaparam.pem
