I tried it out but maybe I'm using a wrong program or I'm using it wrong I'm using this program http://www.gpg4win.org/ and it seems to be a good one. It's an open replacement for PGP.

This might go a bit off-topic but... Problem is that when I sign my epub file, it's not anymore an epub file but a GPG file. Would be nice if it would still remain as an epub file so it could be read normally. I don't know have you used digital signatures for your e-books but for me it seems that when signing a file, it changes the file format until it's opened again with correct key.

I found this good tutorial http://www.glump.net/howto/gpg_intro#signing_files and it says: "Text messages can have signatures appended to them without disrupting the contents of the message too much, but binary files such as Microsoft Word documents and Zip archives can't have arbitrary data attached to them. To sign binary files, it is costumary to have GPG create a separate signature file."

If I want to sign my epub file, I would have to create separated file which contains my signature. Is there a way to sign my epub file without the file format being changed or creating a separated signature file?
