Yeah, I am only representing the ciphertext in hex right now for the
online version. Now, I could modify it to encode the ciphetext in base
64 or something a little more "dense", so to speak... Fwiw, here is a
link to a C based test version, have you seen it yet?

Well, what errors did you get? Many others were able to compile and run
it wrt encrypt and decrypt cycles on various plaintexts.

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

I have not. Sorry! Been working lately.

You should really try and use it.

Hummm... Agreed. Also, I have you to query if I have any issues.

 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.

Thanks Stefan. :^)

 You're welcome!
 

It is probably the easiest to
use encryption program out there and it uses modern ciphers and
no need for WWW based encrypted message exchange.

The only reasons I created an online version of it was for "convenience"
and just to see if I could do it to begin with. Its client side only. I
thought, sending the ciphertext in a url was be an easy way. Hex
encoding was simple enough. Keep in mind that my cipher is purely
symmetric at this stage.

 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.
 

I am also thinking of creating a key pair for sci.crypt, so that
we no longer have to use SCOS, because SCOS was floating around
on Bitmessage, as C, Pascal and Go code.

but not Go. Fwiw, I am friends with somebody who is/was on the Go team.
Not sure if he still works for Google. I have not talked to him in some
months.

 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.
 

He is a very smart person and I feel great to be able to converse with him about many things.
