I disabled vatId authorization in version 3, located in SessionOperations>>processIWant | SessionOperations>>processIAm:.
I was asked to disseminate my news to Pharo Users, hello there. I was asked to describe ParrotTalk well, provide use cases and adopters of its use. Alright, I will give an attempt.
ParrotTalk is an encrypted connection framework. 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.
https://github.com/ZiroZimbarra/callistohouse/blob/master/docs/ParrotTalkFra...
For as to use cases, this encrypted connection has no third party, man-in-the-middle situation by not using Certificates. 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.
http://www.squeaksource.com/Cryptography/Cryptography-zzz.111.mcz http://www.squeaksource.com/Cryptography/ParrotTalk-HenryHouse.3.mcz
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.
http://www.squeaksource.com/Cryptography/elinda-HenryHouse.14.mcz http://www.squeaksource.com/Oceanside/hubbub-HenryHouse.38.mcz
Hubbub currently fails to load correctly in Pharo. In Squeak the two ParrotRemoteTestCases: LookupTestCase and OperationalTestCase really screw everything up, do not save an image after running. 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.
The shift away from vatId authorization should not adversely affect hubbub, we hope! When STON starts to work, and I think I need to turn off jsonMode, then traffic between vats can start to be analyzed and figure out how resolving is working with redirectors invoked remotely.

If I google... parrottalk protocol nothing seems related. So what is ParrotTalk?
P.S... since this is not "part of" pharo, [pharo-users] would be a better place for discussion than [pharo-dev]. Could you re-announce there, with some description of use cases and who/where the protocol is used?

I have developed the ParrotTalk Protocol, documented in part here[1], while I have two implementations: 1 in Squeak/Pharo [2 a/b] and the other in Java [3 a/b]. Particulars of some decisions are absent from the specification: namely the MAC key and ivSequence derivations, as well as constrained traffic signing; they are in the implementations. I will update the 3.6 slideshow to specify these items.
Thank you.

I have a question about my derivation of a MAC key. It is very complicated and I am considering ways to simplify for use by potential language implementations. Here is the current derivation in Squeak/Pharo. Should I just use the sharedKey as the SHA1HMAC key or some simplified hash of the sharedKey, without all the pad hashings I am doing? What do you think? I want to hear from you.
makeHMAC
| sharedKey hashPadder macKey | sharedKey := diffieHellman sharedKeyPadPositiveByteArray. hashPadder := self class. macKey := MD5 hashMessage: ( (hashPadder hash: sharedKey pad: 16rCC), (hashPadder hash: sharedKey pad: 16rBB), (hashPadder hash: sharedKey pad: 16rAA), (hashPadder hash: sharedKey pad: 16r99)). macKey := macKey, (MD5 hashMessage: ( (hashPadder hash: sharedKey pad: 16r88), (hashPadder hash: sharedKey pad: 16r77), (hashPadder hash: sharedKey pad: 16r66), (hashPadder hash: sharedKey pad: 16r55))). macKey := macKey, (MD5 hashMessage: ( (hashPadder hash: sharedKey pad: 16r44), (hashPadder hash: sharedKey pad: 16r33), (hashPadder hash: sharedKey pad: 16r22), (hashPadder hash: sharedKey pad: 16r11))). ^ SHA1 new hmac key: macKey.
Would a better way forwards is simply this?
makeHMAC
macKey := diffieHellman sharedKeyPadPositiveByteArray. ^ SHA1 new hmac key: macKey.

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".

I was asked to disseminate my news to Pharo Users, hello there. I was asked to describe ParrotTalk well, provide use cases and adopters of its use. Alright, I will give an attempt.
ParrotTalk is an encrypted connection framework. 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.

I was a latecomer to all the work the Cryptography Team put together, all functions and ciphers and hashes they put together. I helped add ASN.1, later on. They did the hard work I put some pieces together. I heard someone likes it. That makes me happy.

I hope that doesn't discourage you, and I'm interested to hear a more useful reply from anyone else. cheers -ben
P.S. I just bumped into what looks like an interesting intellectual exercise... http://cryptopals.com/

I have developed the ParrotTalk Protocol, documented in part here[1], while I have two implementations: 1 in Squeak/Pharo [2 a/b] and the other in Java [3 a/b]. Particulars of some decisions are absent from the specification: namely the MAC key and ivSequence derivations, as well as constrained traffic signing; they are in the implementations. I will update the 3.6 slideshow to specify these items.
Thank you.

More celebration requested. I got encrypted data passing between Squeak/Pharo and Java: AES with CBC and IVs and SHA1 HMAC. It works! NSA-proof crypto rocking Squeak, Pharo & Java!
*Celebrates again, drinks for everyone*

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".

I disabled vatId authorization in version 3, located in SessionOperations>>processIWan t | SessionOperations>>processIAm: .
I was asked to disseminate my news to Pharo Users, hello there. I was asked to describe ParrotTalk well, provide use cases and adopters of its use. Alright, I will give an attempt.
ParrotTalk is an encrypted connection framework. 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.
https://github.com/ZiroZimbarra/callistohouse/blob/master/docs/ParrotTalkFra...
For as to use cases, this encrypted connection has no third party, man-in-the-middle situation by not using Certificates. 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.
http://www.squeaksource.com/Cryptography/Cryptography-zzz.111.mcz http://www.squeaksource.com/Cryptography/ParrotTalk-HenryHouse.3.mcz
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.
http://www.squeaksource.com/Cryptography/elinda-HenryHouse.14.mcz http://www.squeaksource.com/Oceanside/hubbub-HenryHouse.38.mcz
Hubbub currently fails to load correctly in Pharo. In Squeak the two ParrotRemoteTestCases: LookupTestCase and OperationalTestCase really screw everything up, do not save an image after running. 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.
The shift away from vatId authorization should not adversely affect hubbub, we hope! When STON starts to work, and I think I need to turn off jsonMode, then traffic between vats can start to be analyzed and figure out how resolving is working with redirectors invoked remotely.
