Definition: It's a Linux file used for SSL (Secure Sockets Layer) configuration in the external directory. Detailed definition: "External directory" refers to a location where an external program or service can store its configuration files, often stored within a user's home directory or in other secure directories. This file is used by the OpenSSL library when creating a secure connection between two different systems. The 'ssl_sasl_EXTERNAL.conf' specifies various aspects of SSL connection settings. It includes details like certificate verification (optional), server keys, client certificate, and more, which are essential for an effective SSL connection. This configuration file plays a crucial role in securing connections between applications or services that don't trust the same host (the 'external' directory). It's fundamental to ensure that the connections are secure, avoiding potential breaches like man-in-the-middle attacks.
