Build and Test

go mod tidy
go build -o beta ./cmd
./beta b64 to "test"
./beta b64 from "dGVzdA=="
./beta b64 encode -i hej.txt -o hej.b64
./beta b64 decode -i hej.b64 -o hej2.txt

go test ./cmd
go test ./cmd -v
go test ./util/aesutil/

Comments

Use fmt.Println() instead of cmd.Println() to print to stdout (to for example use > into a file) But, this makes it hard to test the output from a command.

Rune is an int32, but by convention used to store charachters: []rune(str)
