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.

Hi Philip and thanks for the reply.
I am learning how to use these tools and trying to understand how the various
options for signing and also securing documents. I am using Linux (openSUSE)
for all this but no doubt windows users as addressees will be viewing and
reading.
I have two different objectives:-
1. To insert a signature or rather an image of a signature in the right place in a
document and in adding this signature image, render the document "signed" so
that it cannot be altered without warnings or better.
2. To secure a document so that is cannot be read or amended by an
unauthorised and, even if read by an unauthorised person, cannot be altered.
I can use PGP type encryption on emails etc already either to sign a message or
to encrypt a message using my email client but am trying to work out how to do
this with a LO document or spreadsheet which may need to be converted into a
pdf.
Is there a simple step by step guide for this?
If I wish to store my private key for an LO signature will it go to the same
"safe" as my PGP keys or my KeePassXC password manager?
I need to have the signature image which can be used like a "stamp" and added
to any document and there may be issues of scaling the size of the image to suit the
environment in which it is used.
If anybody can shine more light it would be very much appreciated.
Budge.

I am trying to insert a signature line at the end of a spreadsheet and the text which
appears in the for name and title are much smaller than the font setting for the sheet.
Where is this text font defined and how can I change it. Also the date is not shown
although the date option has been ticked for "show date in signature line."
Please can somebody advise?

As I understand it, the date is only added when you sign the signature line
with a digital certificate. The creation of a signature line is a separate
activity from the signing of that digital line.
When you insert the signature line, it shows your name and status in an image
box. If you hover over this image box and then right click, the context box
shows at the bottom the option to sign the signature line. In order to do
that, you must have previously created a digital certificate in the form of an
X509 certificate which you save in LO.
