Oh, I don't remember. It's been a while.

You just need to install the latest version of Go and then run
in the directory of minicrypt: go build -ldflags "-s -w", for
an optimezed version, instead of go build.

Understand! I was also not complaining about your cipher. It is just
the fact that I do not like the idea of visiting the WWW, when encrypting
or decrypting.

Oh, interesting. :-) Go is IMHO pretty cool, because it has so many libraries,
you can find on GitHub and most new and cool crypto stuff etc. is either
written in Go or Rust.
