title: 'Transport Layer Security Support'

description: |-
    Support for Transport Layer Security (TLS), and its predecessor, the Secure
    Sockets Layer (SSL), is included in Red Hat Enterprise Linux in the OpenSSL software (RPM package
    <tt>openssl</tt>).  TLS provides encrypted and authenticated network
    communications, and many network services include support for it.  TLS or SSL
    can be leveraged to avoid any plaintext transmission of sensitive data.
