Conversation
WalkthroughThe recent updates enhance the mProxy application by introducing CoAP functionality, supporting both DTLS (Datagram Transport Layer Security) and non-DTLS communication. Key improvements include renaming configuration variables for consistency and adding comprehensive examples for CoAP clients and servers. These changes significantly improve security, flexibility, and usability, marking a notable advancement in protocol handling. Changes

21-21: Update togithub.com/caarlos0/env/v11is noted. Ensure all dependent configurations are compatible with this version.Verification successful
The extracted code snippets show that the
envpackage is used primarily for parsing environment variables into configuration structs using theenv.ParseWithOptionsmethod. This usage pattern is consistent across multiple files.To ensure compatibility with version 11 of the
envpackage, I reviewed the documentation forgithub.com/caarlos0/envand found no breaking changes or new features in version 11 that would affect the current usage patterns in the codebase.Therefore, the update to
github.com/caarlos0/env/v11appears to be compatible with the existing configurations.

Ensure secure handling of sensitive data.
The auth variable contains a token that should be securely managed. Consider using environment variables or a secure vault for sensitive data.

Refactoring of Load function to LoadTLSConfig.
The refactoring to support both TLS and DTLS configurations improves modularity and maintainability. Ensure that MinVersion is set for both configurations to enforce secure protocol versions.
+ config.MinVersion = tls.VersionTLS13+ config.MinVersion = dtls.VersionDTLS12
