A while back I started an implementation of TLS 1.2. Rob Withers joined the effort a few weeks ago and is has made terrific progress. He reorganized everything, added a proper protocol stack, and now has the certificates working.
Our version now works with SSL3.0 and TLS 1.1, and DH or RSA using x509v3 Certificates. There are still a number of things that need to be done but we can now use squeak to connect as an SSL server and/or client. See the examples in the workspace that opens when you load the code. You will find our implementation at www.squeaksource.com/Cryptography. There are two Monticello Configuration files available to make loading easier. Load Cryptography-Configuration.mcm, and then Crypt-Xtra-Config.mcm.
We could use some help with testing, code review, documentation or any other help you would like to offer.
There is also support for MS CryptoAPI and CertificateStores for Microsoft in the MSCert package. In the future I will be working on integrating this functionality. I will also be adding support for KomHttp which is mostly completed but needs to be updated to support Rob’s new version.
We hope you find this useful and will keep us updated on your use and issues with our implementation. If you have any questions please let us know. Also again we would like to invite anyone with interest or experience with cryptography to join our Cryptography Team athttp://lists.squeakfoundation.org/mailman/listinfo/cryptography .
