* all: run gofumpt
https://github.com/mvdan/gofumpt
The main appeal for me here is that my (and many other peoples')
editors run this on save, so doing a single diff here
keeps other diffs minimal.
* .github/workflows: add gofumpt checker
* remove unused logs
* add banner to server password
* add updated crypto lib
* add test
* refactor: clean up whitespace in banner test
* fix: update test case name to use underscores for consistency
