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

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.
