OpenSSL "genpkey -genparam" - Generate DH Parameters

Q

How to generate a new DH parameter file using OpenSSL "genpkey -genparam" command?

✍: FYIcenter.com

A

If you need a new DH parameter file in order to create new DH keys, you can use the OpenSSL "genpkey -genparam" command as shown below:

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

OpenSSL> genpkey -genparam -algorithm dh -out my_dh.prm

-----END DH PARAMETERS-----

Options used in this command are:

"-genparam" - Generate key generation required parameters
"-algorighm dh" - Use DH algorithm
"-out my_dh.prm" - Save output (the new DH key generation parameters) in a file.
