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?

Yes, I remember that and I had compiler errors.

 
You never got it compile with C99?

 
I tried with gcc and g++, but it is ok.

 
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.
 

 
 

Have you tried my minincrypt yet? It is probably the easiest to
use public key encryption software. ;-)

 
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.

 
:^) Fwiw, I never compiled any Go code in my life. C and Pascal, yup,
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.
