Beyond Linux® From Scratch - Version 6.3

Chapter 4. Security

GnuPG-1.4.7

Introduction to GnuPG

The GnuPG package contains a public/private key encryptor. This is becoming useful for signing files or emails as proof of identity and preventing tampering with the contents of the file or email. For a more enhanced version of GnuPG which supports S/MIME, see the GnuPG-2.0.8 package.

Installation of GnuPG

Install GnuPG by running the following commands: 

./configure --prefix=/usr --libexecdir=/usr/lib &&
make

If you have teTeX-3.0 installed and you wish to create documentation in alternate formats, issue the following command: 

make -C doc pdf html

To test the results, issue: make check.

Now, as the root user: 

make install &&
chmod -v 4755 /usr/bin/gpg &&

install -v -m755 -d /usr/share/doc/gnupg-1.4.7 &&
mv -v /usr/share/gnupg/{FAQ,faq.html} /usr/share/doc/gnupg-1.4.7 &&
install -v -m644 \
    doc/{highlights-1.4.txt,OpenPGP,samplekeys.asc,DETAILS,*.texi} \
    /usr/share/doc/gnupg-1.4.7

If you created alternate formats of the documentation, install it using the following command as the root user: 

cp -v -R doc/gnupg1.{html,pdf} /usr/share/doc/gnupg-1.4.7

Command Explanations

--libexecdir=/usr/lib: This command creates a gnupg directory in /usr/lib instead of /usr/libexec.

chmod -v 4755 /usr/bin/gpg: gpg is installed setuid root to avoid swapping out sensitive data.
