Rondon, Using Rebol View 2.7.8.3.1 on Win/XP I ran your test and 
decrypt gives back "This is a string"

Mike, I'm using Rebol /Cmd, because when I call rebol/view at my 
isp, I receive an error of libX not found..

gab, right. e.g md5 for simple password security and rsa for dataflow. 
the javascript link above containing RSA functions too just to step 
in.

Graham: IIRC Maarten was able to use AES with REBOL and OpenSSL. 
I seem to remember that I had tried that and was successful as well. 
In any case, the only reason I can think of that would make it not 
work is a difference in the IV and padding.

Graham: I was able to implement TLS1.0 protocol configured to use 
the TLS_RSA_WITH_RC4_128_SHA cipher-suite. All the mentioned algorithms 
were calculated using the  build-in Rebol2 encryption functionality. 
I had no problems regarding the compatibility. I haven't tried the 
cipher-suite with the AES enctryption though but my guess it will 
work as well.

Cyphre: do you plan to release it in open source? Is your implementation 
client-side, server-side or both? It would be a great addition to 
Cheyenne to support SSL natively.

That's how imo SSL support should be implemented - not as an hardwired 
C implementation, but using Rebol crypto facilities, and being part 
of Core, not Command ...

Interesting ...

Ditto on what doc says

Doc: the code is in sort of "prototype state" and It was meant as 
possible implementation for R3 in future (once Carl put the encryption 
algorithms codebase into the R3/host-kit or someone write an extension 
for that).

I wrote it because I wanted to know if we could get rid of unnecesary 
C code that is currently in R2 to just handle the protocol logic 
while the performance of the crypto algorithms will remain in C. 
The current size is less than 20Kb of Rebol script code so IMO it 
could be useful and also easier maintainable way.

Currently it works in client-side mode only but there is already 
support for ASN.1 certificates also I tried to write the code so 
the server-side mode and other cipher-suites shouldn't be hard to 
add.

I plan to release the prototype to open public after some cleanup 
but if you want to waste some time with the current 'raw stuff' just 
post me privately and I'll send you a copy.

github?

ok, you can get it here: https://github.com/cyphre/tls-prototype

(use at your own risk ;))

Cool, thanks Cyphre! There's no license attached, you should at least 
add a MIT/BSD license in the header.

+1

Thanks Cyphre, _much_ appreciated.

Doc: license added.

Thanks. :-)
