Hello

What is the best way to email a document or image to someone securely, without them needing to install any special applications?

e.g. I need to send a passport photograph to someone.

One option would be to zip it up using the free utility 7-zip, and add a password to the archived Zip file, however business computers often stop their normal users from installing any applications. I don't need "industrial strength" encryption just something basic but with a good password should do.

Any thoughts?

Have a look here

Perhaps one of the web based options might be worth your consideration.

The trouble with any web based option is
a) What does it cost?
b) If free what is their business model - and how can we trust it?

I was very much hoping that Microsoft might have built some sort of encryption into Windows 10... no?

I have a simple way. But I do not know whether or not, it is foolproof.
You could copy an image to a word document and save that document as .odt file.
.odt format is used very rarely as most people use.docx format most of the time.

If they can open a .odt file then it is plain bad luck.

Surely .odt is "Open Document Text"? This is a very standard format. In fact I think msWord can open it, no?

Doesn't sound remotely secure to me!

I use Rar or 7z to encrypt and then and the receiver knows the (pre arranged pass). and never a issue...

Encrypt is what it is called. as i recall MS tells you to right click file or folder, look and click Advanced and either compress or encrypt.

It is very strongly recommended you backup your Key to a external USB.
