Hi Guys: I'm an smalltalker from Argentina. I works mainly with Dolphin and Squeak and I'm in the security software development field. (Currently I'm developing a product focused in securing personal data). Cryptography is the core technology of my actual software development work, then I'm here to learn and help as far I can. My actual free time isn't too much, but I will try my best. Best Regards. -- Germán S. Arduino http://www.arsol.biz http://www.arsol.net

Wonderful! I think that having someone that is focused on the usage side, that can help to write tools, and that can help to use cryptology, or to have as a model for how to use cryptology would be terrific. I've added you to the repositories. Please let us know if you need help getting started, and feel free to post your code. I would assume that your application is for ciphers. Since the code in the ciphers would be necessary for your code to work, how about you put it there (the repository for cryptography ciphers on squeak source)? That way we can take a look. Also consider learning more about the implementation side, or staying up with the projects we are working on. There is no better way to build tools then to understand in a broad way the technology that is used, or why they exist and for what purpose they were invented. We are starting with ASN.1 which is really a communication protocol. Thanks for your participation and welcome to the team!

Ron, I am interested in being part of this. I have been studying and working on a Cryptography facade for the last couple of months and really enjoying the fruits of this labor. Its called "KryptOn" and I plan to share it real soon now. My understanding of Cryptography is more on the usage side though, not the implementation side.. I don't have the math skills to fix/maintain/develop the actual cryptographic algorithms, just a pretty good understanding of their proper usage, and key management, etc. - Chris

Welcome again to the Cryptography Team

All, Hopefully the mailing list will make it easier for us all to communicate. As Sean pointed out this group has a lot of work to do and the work is not easy. But that doesn't mean it has to be unpleasant. I hope that we can make it enjoyable for everyone. We are still planning what needs to be done. The current open items are: Review ANS1. Download Cincom non-commercial version when you get a chance. Wait for response from Mr. Robertson at Cincom about license issues and support. Thanks again for your participation, Ron

License Issues / base image cryptography
by Ron Teitelbaum 21 Oct '05

All, Ok so we have started a cryptography team. There is a new Cryptography List you can sign up at: http://lists.squeakfoundation.org/mailman/listinfo/cryptography We are still looking for volunteers if you have an interest, have some experience, or need cryptography for your application please volunteer. We are starting with ASN.1 which could also be used to help optimize communications between systems. From there we will move on to x.509v3 and PGP. One of our members suggested that we contact Cincom, which we did. We asked if a port of Cincom code was possible, and we received a positive reply. The only issue that came up was about license rights. We are waiting for a more definite response, but so far they are not comfortable with Squeak license. They would prefer LGPL or the Artistic License for the code that we port from them directly. I've read through them but I'm not an expert on licenses. Can you give me your reactions to using either one of these license models for our cryptography packages? What would the general reaction be? Has anyone compared the models enough to tell me the difference between Squeak and LGPL? For LGPL I understood the extra requirements to separate functionality of the package form the applications so that it can be run separately and the source code availability requirements which considering that this is smalltalk and source is always available we can include the license on the class comment to make sure that developers include this notice in their applications. We have not decided to go this route; we are just exploring the options. Also, there are currently PKI classes in the base image. Those classes are duplicated in the current cryptographic package. Does anyone have an opinion on whether or not cryptographic classes should be in the base image? If so what pieces do you think should be there? Your thoughts are welcome. Thanks, Ron Teitelbaum
