OpenSSL "dsaparam" - Generate DSA Parameters

Q

How to generate a new DSA parameter file using OpenSSL "dsaparam" command?

✍: FYIcenter.com

A

If you need a new DSA paramter file in order to create new DSA keys, you can use the OpenSSL "dsaparam" command as shown below:

C:\Users\fyicenter>\local\openssl\openssl.exe

OpenSSL> dsaparam -out my_dsa_2048.prm 2048
Generating DSA parameters, 2048 bit long prime
