About this guide https://www.howtoforge.com/tutorial...-and-ubuntu-server-against-the-logjam-attack/ My OS is Debian Jessie and I use nginx as stand alone web server. Do I need to update OpenSSL to 1.02 in the first place before run that instructions ? Also, how to update OpenSSL to 1.02 in Jessie ? Do I need to generate key again (CSR & key) and reissue my commercial SSL ? Thank you.
