Ttf dsig

Anyone know how I might be able to continue signing (DSIG) my TTF files now I’ve moved my projects over to Glyphs from FL?

I could always take them back to FL, but would like to know if there’s another way.

Using TTX?

I have a certificate, I don’t want to used dummy sigs.

I will have a look.

Miles it works the same way, just with your dsig instead of the empty one.

thanks

Mekkablue is not correct. It is quite complicated. You have to prepare the font data in a certain way and then calculate a checksum and run encode it with your signature. Then put the font together and add the checksum to the dsig table. I will see if I can figure this out.

Thanks George,
signing ought not be something that needs thinking about, just a checkbox on export.

It should be like this for the user, of course. I just wanted to explain what it is all about. I hope I figure this out.
