Subject: remove the dependency on gpg
X-Git-Url: https://code.communitydata.science/uw_tex_letterhead.git/commitdiff_plain/0bb99e94619f2a166e67f61a0289a341472e1832

remove the dependency on gpg

I removed the dependency on GPG by making the encrypted signature file optional
rather than required.

-The signature file (a gray image) is GPG encrypted file using a
-symmetric cipher. The passphrase is "weakpassword" (without

-need GPG installed in the system.

+Encrypted signatures files
+===========================
+
+If you'd like, you can encrypt the signature file. There are several
+lines you in the Makefile you can uncomment to do this. We've included
+an optional encrypted copy of the fake signature file. To use it, the
+passphrase is "weakpassword" (without quotes). You will want to
+customize this. To use this, you will also need the GNU Privacy Guard
+(GPG) installed on your system.
