Mastering Sasl Plain & Ssl Setup For Apache Kafka!

SASL (Simple Authentication and Security Layer) is a framework for adding authentication support to connection-based protocols. It allows a protocol to define a mechanism for authenticating clients and optionally encrypting or securing communication between the client and the server.
In the context of Apache Kafka, SASL is used for client-server authentication, ensuring that only authorized clients can produce or consume messages. Kafka supports multiple SASL mechanisms, including PLAIN, SCRAM, GSSAPI (Kerberos), and others.
The SASL/PLAIN mechanism is one of the simplest authentication mechanisms in SASL, where the client sends a username and password in plain text to authenticate itself to the server. While this is simple, it is recommended to use it with encryption (like SSL/TLS) to ensure that the username and password are not transmitted in clear text over the network.
