Generate new DSA Key from OpenSSL Parameters File

See more DSA Examples

Generates 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
