I wanted to share my good news, though I have not yet gotten Pharo, Squeak and Java talking. What I was able to accomplish, after finishing the port of Cryptography's ASN1Types, Module and Streams is to get Java's rendezvous and key exchange working. After I got that connecting, I looked at the ciphers, ivSequences and MAC and got that working. In Java, I am now able to encrypt and decrypt "hello world".

Currently allowing anonymous 2048-bit key negotiation to establish user-provided encryption cipher and user-provided encoding and decoding, both through a provided SessionAgentMap to a starting SessionAgent server. Please look in the test case ThunkHelloWorldTest for building these maps and running a connection iwth data passing after encryption is established. There is a 4-way negotiation, from ProtocolOffered/Accepted to Go/GoToo. In using RSA 2048 signature validation and DH 2048 primes to establish the key used within the selected Cipher. The Cipher and Encoder are selected by name through the negotiation protocol. Currently three Ciphers are selectable, AESede, DESede, and DES. There are two encoders tested, asn1der, and Bytes. This protocol is described here, in this document.

As such, this is a tight implementation of NSA-proof encryption without explicit authorization beyond knowledge of a host:port. The use cases involve any communication desired to be encrypted with such high encryption. The support will last my lifetime, so we have a settled solution, here in the third version, provided here. It requires version 111 of Cryptography, as a prerequisite. Both run on Squeak and Pharo.

> The current use is with my hubbub system, a promise-based distributed object implementation. I am working to bring ParrotTalk to Java and allow hubbub to operate interdependently between Squeak, Pharo, Java and any other languages which can support ParrotTalk and STON. My latest efforts with hubbub are to bring STON as the Layer 6 encoding. Hubbub depends on eLinda.

I never run these tests until I get a better handle of serialization. Currently, do to a shift in progress to STON, the serialization tests fail, just the way we like it. Fix the tests then the system starts to work right.

This session think would have the stacks for each protocol version SessionOperation registered by protocol in a Tuple, for eventual callback. When the ProtocolOffered comes in we publish the tuple frame, with set selected version, to route to the correct SessionOperation to support each version of the protocol.
