The purpose of 'secret 7' in Cisco encryption is to secure cleartext in configuration files. It uses a reversible encryption method to obfuscate passwords within the device configurations, making them more challenging for unauthorized users to read when they access the configuration files. This form of encryption is not intended for strong security but instead provides a layer of protection for sensitive information by transforming readable text into an encoded format.

In the context of network devices, "secret 7" is often implemented as a quick means of safeguarding sensitive data such as passwords while allowing for relative ease of access for those with the necessary permissions. The choice to obfuscate passwords rather than use stronger encryption methods reflects a balance between usability and security in the management of network equipment.
