Find and fix weak OpenSSL/OpenSSH keys

A recent vulnerability was found in the OpenSSL package as provided by Debian and Debian-based Linux distributions, such as Ubuntu, that broke the effectiveness of the OpenSSL PRNG (Predictable Random Number Generator). This vulnerability caused OpenSSL to generate weak keys for anything relying on OpenSSL, including SSL certificates, OpenSSH keys, and OpenVPN keys. Any OpenSSL-based key generated on a Debian-based system since September 2006 by the openssl, ssh-keygen, or openvpn –keygen commands are vulnerable to this issue….

You will have to enter your sudo password to complete this task.

Once this directory is created, place all your *ttf or *TTF files in the newfonts directory. With the fonts in place you will then need to issue the command fc-cache -f -v to make the system aware of the new fonts. Once this is done, the system knows about the new fonts and all the system users will have access to them.

If you want to make these fonts available only to specific users, then you will follow the same directions except you will add the fonts only to the users’ ~/.fonts directory. If the ~/.fonts directory doesn’t exist, create it with mkdir ~/.fonts (while logged into the specific users’ accounts). Now move (or copy) all of the *ttf and/or *TTF files into the new directory and run fc-cache -f -v to make the users’ accounts aware of the fonts.

If you have a single-user machine, go with the latter version……
