GnuTLS の概要

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 protocol specification:

The TLS protocol provides communications privacy over the Internet. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery.

GnuTLS provides support for TLS 1.3, TLS 1.2, TLS 1.1, TLS 1.0, and SSL 3.0 protocols, 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.

本パッケージは LFS-11.1 において正しくビルドでき動作することが確認されています。


GnuTLS の依存パッケージ





Doxygen-1.9.2, GTK-Doc-1.33.2, Guile-3.0.7, libidn-1.38 または libidn2-2.3.2, libseccomp-2.5.2, Net-tools-2.10 (used during the test suite), texlive-20210325 or install-tl-unx, Unbound-1.13.2 (to build the DANE library), Valgrind-3.17.0 (used during the test suite), autogen, cmocka and datefudge (used during the test suite if the DANE library is built), and Trousers (Trusted Platform Module support)



libtasn1-4.17.0 をインストールしない場合、GnuTLS の tarball 内に含まれる旧バージョンが利用されます。


GnuTLS のインストール

以下のコマンドを実行して GnuTLS をビルドします。

./configure --prefix=/usr \
            --docdir=/usr/share/doc/gnutls-3.7.2 \
            --disable-guile \
            --disable-rpath \
            --with-default-trust-store-pkcs11="pkcs11:" &&

ビルド結果をテストする場合は make check を実行します。

root ユーザーになって以下を実行します。

make install

configure スクリプトにて --enable-gtk-doc オプションを指定した場合は API ドキュメントが自動的にインストールされます。 これを指定しない場合であってもドキュメントをインストールしたければ root ユーザーになって以下のコマンドを実行します。 ドキュメントは /usr/share/gtk-doc/html/gnutls にインストールされます。

make -C doc/reference install-data-local


--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-0.24.0 is not installed.

--disable-guile: This switch disables GUILE support, since GnuTLS does not support Guile-2.2.x yet.

--disable-rpath: This switch prevents building GnuTLS utilities and tests with hardcoded runtime library search path. Hardcoded rpath is unneeded for BLFS, and it causes test failures if an old version of GnuTLS is 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-0.24.0 is not installed.

--enable-gtk-doc: GTK-Doc をインストール済で API ドキュメントを再構築する場合に指定します。

--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-0.9.10.
