How To Install libgnutls-openssl27 on Ubuntu 20.04
Introduction
In this tutorial we learn how to install libgnutls-openssl27 on Ubuntu 20.04.
What is libgnutls-openssl27
libgnutls-openssl27 is:
GnuTLS is a portable library which implements the Transport Layer Security (TLS 1.0, 1.1, 1.2, 1.3) and Datagram Transport Layer Security (DTLS 1.0, 1.2) protocols.
GnuTLS features support for:
- certificate path validation, as well as DANE and trust on first use.
- the Online Certificate Status Protocol (OCSP).
- public key methods, including RSA and Elliptic curves, as well as password and key authentication methods such as SRP and PSK protocols.
- all the strong encryption algorithms, including AES and Camellia.
- CPU-assisted cryptography with VIA padlock and AES-NI instruction sets.
- HSMs and cryptographic tokens, via PKCS #11.
This package contains the runtime library of the GnuTLS OpenSSL wrapper.
