Updated Go version in Dockerfile and go.mod to ensure better compatibility and unpinned the Go version in Dockerfile for increased flexibility. Multiple dependencies in go.mod and go.sum have been updated to their newer versions for improved functionality and security. This will keep the project up-to-date with the latest features and bug fixes offered by these dependencies. Removed unused dependencies to keep the project clean and efficient.
Reorganized the Go package structure, moving the main package to 'cmd'. Upgraded the flag library to Cobra for better management of CLI commands. This included moving the X25519 key generation from a flag to its own standalone Cobra command, which improves user interaction and code modularity. This structural change will benefit future additions and code maintainability.
