Re: [libreoffice-users] Signature Line in Calc - Where is text size determined?

Further to my last reply, you can encrypt a Writer file using pgp within LO Writer. You can see the 
option in File > Save As  but you will need an Openpgp client on your system and you will need to 
have created a private/public key pair. Most all linux distributions already have a pgp client 
installed [gnupg ?] but Windows users will need to install gpg4win.
