Question

Why the PHP function phpinfo() shows two OpenSSL versions?

Answer

Currently, the cPanel repositories provide two OpenSSL versions:

ea-openssl.x86_64 : Cryptography and SSL/TLS Toolkit
ea-openssl11.x86_64 : Cryptography and SSL/TLS Toolkit

The current version, which is ea-openssl11, is installed by default on new cPanel servers. However, if the server was customized or the package was installed afterward, it is possible to end up with the two packages
in the system.

To confirm which versions are installed, the following can command can be executed:

rpm -qa|grep ^ea-openssl

If the output of the command shows to versions:

ea-openssl-1.0.2u-1.1.3.cpanel.x86_64 <-- older
ea-openssl11-1.1.1h-1.1.1.cpanel.x86_64 <-- newer

The oldest version can be removed with the following command:

yum erase ea-openssl
