Introduction to GnuTLS
The GnuTLS package contains
libraries and userspace tools which provide a secure layer over a
reliable transport layer. Currently the GnuTLS library implements the proposed
standards by the IETF's TLS working group. Quoting from the
TLS 1.3 protocol
specification :
“ TLS allows
client/server applications to communicate over the Internet in a
way that is designed to prevent eavesdropping, tampering, and
message forgery. ”
GnuTLS provides support for TLS
1.3, TLS 1.2, TLS 1.1, TLS 1.0, and (optionally) SSL 3.0 protocols.
It also supports TLS extensions, including server name and max
record size. Additionally, the library supports authentication
using the SRP protocol, X.509 certificates, and OpenPGP keys, along
with support for the TLS Pre-Shared-Keys (PSK) extension, the Inner
Application (TLS/IA) extension, and X.509 and OpenPGP certificate
handling.
This package is known to build and work properly using an LFS 11.3
platform.

Installation of GnuTLS
Install GnuTLS by running the
following commands:
./configure --prefix=/usr \
--docdir=/usr/share/doc/gnutls-3.8.0 \
--with-default-trust-store-pkcs11="pkcs11:" &&
make
To test the results, issue: make
check.
Now, as the root user:
make install
Command Explanations
--with-default-trust-store-pkcs11="pkcs11:":
This switch tells gnutls to use the PKCS #11 trust store as the
default trust. Omit this switch if p11-kit-0.24.1 is not
installed.
--with-default-trust-store-file=/etc/pki/tls/certs/ca-bundle.crt:
This switch tells configure where to find the
legacy CA certificate bundle and to use it instead of PKCS #11
module by default. Use this if p11-kit-0.24.1 is not installed.
--enable-gtk-doc: Use this parameter if
GTK-Doc is installed and you wish
to rebuild and install the API documentation.
--enable-openssl-compatibility: Use
this switch if you wish to build the OpenSSL compatibility library.
--without-p11-kit: use this switch if
you have not installed p11-kit.
--with-included-unistring: uses the
bundled version of libunistring, instead of the system one. Use
this switch if you have not installed libunistring-1.1.
