ConfigurationOfCryptography and Pharo 5.0
by Esteban Lorenzano 20 Apr '16

20 Apr '16

Hi, I made ConfigurationOfCryptography to load properly in Pharo 5.0… and made the tests pass (just one yellow that I don’t know how to fix because I’m not a “crypto guy”) :) Can I have permission to upload this files? (I’m “EL” in squeaksource). thanks! Esteban

update forthcoming for SecureSession
by Robert Withers 15 Apr '16

15 Apr '16

I need to give you all a heads up that I will release a new version in coming days, with a potential change to the encryption. I must do some coding and testing first. This protocol change will break any currently installed versions V1, so please consider this alpha code at this point. Thank you. -- Robert . .. ... ^,^

SecureSession in Pharo5 (was Re: SecureSessionV1 is green)
by Robert Withers 14 Apr '16

14 Apr '16

I tried to load SecureSession-86 into Pharo and I ran into a couple of issues. I first tried in a 5.0 image I had from December that already had cryptography loaded. I loaded SecureSession and ran the tests which default to using compression. This determined my use of the selectors #zipped/#unzipped, which are missing in Pharo, though it does have compression present. I reloaded Compression-cmm.48 from http://source.squeak.org/trunk and it did not load all of the way, but those selectors I needed did. I ran SecureSession tests and they are all green except for one performance test. The uncompressible performance test failed as I am missing the crytpography plugins; I never was able to build the VM on this Ubuntu laptop, I tried the same in a current Pharo5.0 image and I couldn't even load Cryptography. The bottom line is that SecureSession-rww.86.mcz works fine in Pharo as long as Compression is updated and the ability to load Cryptography is restored. I have only tested a 32-bit spur image on Ubuntu. I would like to ask the community for review on the code, as well as testing on other VMs, for squeak, pharo and newspeak.

Hi Robert! Very nice to see some developments in Cryptography! Nice work on getting to green!

SecureSessionV1Server
by Robert Withers 10 Apr '16

10 Apr '16

Over the course of several months, I've been working on the implementation of SecureSessionV1 to adopt new protocol and message frame definitions. As to the original connection protocol and frames, I preserved it as a backwards compatible Vintage implementation. This change simplified a fair bit of code and will allow for some further modifications. I apologize for my habit in using the code and unit tests to document the system, an old habit to try for a self-describing domain language of secure sessions. Please look in SecureSession-Tests for examples in using both the Vintage and V1 protocols. The key classes for the Vintage version remain SecureSessionServer and SecureSessionTerminal, while the V1 version use SecureSessionV1Server and SecureSessionV1Terminal. Here are some helpful links.. The V1 Frame Design is http://jmp.sh/1Uo0dr7, though I should note there are changes to the DataHeader, which holds the mac and the plaintextLength. The code is found in http://www.squeaksource.com/Cryptography and the SecureSession package requires the Cryptography package and for a notable speed improvements the Cryptography plugins build for your VM. - Robert
