This is a message intended for anyone who was on the Cryptography team.
I recently ported it to Pharo and had to make changes to RandomGenerator class>>unpredictableStringsDo:. This certainly removed some uncertainty from the results of this message. My question is what should I do about that? This method seems to require non-headless, as it is checking the mouse point and such. This being a crypto cornerstone, what the best answer here. Thank you, Robert |

Hi Robert,
Nice to see you! Looks interesting I know that Chris did something gathering sources of entropy. Seems like the more the better. Could you just make the entropy sources optional such that if they exist we use them? I would have to go back and see what Chris did but he was following suggestions from Schneider in his secureRandom.

Hi Ron , nice to see you too! It has been a number of years, hasn't it?
Crypto is timestamped back in 2010, so there is is. I hope these have been kind years to you, as they have for me. I love the idea of optional sources of entropy, depending on the deployed capabilities. So there are our mouse points and such, because they ought to be optional. What are some reliably present sources in the most minimal situation? If we could define minimal as an image with no image level I/O beyond file I/O, I would think we'd have: Kernel, System, Collections, Compiler and FFI. Some intransitives in that scope for entropy would be grand. I was thinking to take 5 millisecondClockValues, separated by 4 non-secure random intervals: take the low order byte of the 4 intervals and reverse & concat them, as a entropic source. I can coordinate these changes. Ron, could you add me to the Cryptography team so I can upload the Pharo Cryptography #bleedingEdge? Thanks and I look forward to more, :) Robert On 10/18/2015 02:38 PM, Ron Teitelbaum wrote: > Hi Robert, > > Nice to see you! > > Looks interesting I know that Chris did something gathering sources of entropy.

Hi Guys,
How about getting the CPU temperature. I think most CPUs support "Digital Thermal Sensor" (I'm not sure about ARM). I think it is seven bits. The real range should be less than that but it may be enough to help add some entropy. Lou On Mon, 19 Oct 2015 07:39:19 -0400, Robert Withers <[hidden email]> wrote: >Hi Ron , nice to see you too!

I think we long ago passed the point where more than 50% of all >32bit cpus were ARM. Typically the temperature of each core is monitored by stuff added around the ARM cores in an SoC, not the ARM itself. For example on a Pi, `vcgencmd measure_temp` works, though strictly speaking that measures the general temp of the SoC - which like many devices that are ARM powered is a large thing to do stuff and just happens to have a few Gips of processor hidden in a small corner. tim -- tim Rowledge; [hidden email]; http://www.rowledge.org/tim Oxymorons: Airline Food |

This is great guys. Is there a way to get this from the image? Good to

hey Ron,
It was actually the Pharo Cryptography team I was thinking of. Perhaps we can get the same package to work in both squeak and Pharo, with use of installable entropy sources or the like. In order to get SqueakElib running in Pharo I need crypto and we may as well do it right.

Yes, if a common package for both Squeak and Pharo is possible, that'd
be great. Otherwise, the Squeak and Pharo versions should reside in separate repositories. Squeak users are still using squeaksource.com, Pharo moved to smalltalkhub and beyond..

Hi All,
Unless someone filed the proper paperwork I would suggest NOT moving the cryptography code anywhere except for SqueakSource. When we started the project we spent time ensuring that we had a proper exemption from the U.S. regulations on exporting cryptographic code. If someone copied and forked the code that exemption may not still apply to that new repository. I'm not personally involved with the code on Pharo, not sure who is doing crypto there.

Heh, well, since then SqueakSource itself was moved to a different
server in a different country. I guess there was also a mirror of SqueakSource hosted in Chile under a different URL for many years. I'm doubtful any of it matters, but we wouldn't want anyone to end up in Gitmo over it. If you're uncomfortable about hosting a copy elsewhere, then please at least namespace-prefix the Pharo-specific packages, to at least help keep it from becoming a tangled mess.

Hi Chris,
The exemption is not for the location of the server but the URL where it is hosted. I'm happy to help in any way I can but I don't have access to the Pharo Repos. I have no issue with having Pharo packages on SqueakSource if that is what everyone agrees too. We have multiple packages hosted there. It's ok with me if we host some pharo code there too.

Ron, would it be an easy process to add a second URL to the exception
paperwork. Pharo does have new ideas about code storage and distribution that we would want to take advantage of. This would help a lot! Then again, screw their paperwork requirements of us. Put my name as responsible on the Pharo code and I'll take a trip to Cuba, if they need a scape goat for their 20th century thinking. Crypto is already out of the bag and everyone uses it freely. Just do it and ask permission later. In thinking about consolidating crypto code between squeak and pharo, I would guess there would be a thin capatibility layer for each system, then the Crypto code in the main. My goal is to have compatibility, crypto and plugins on both virtual platforms.

Hi Robert,
I went back and reviewed and this is what I sent to BIS. http://lists.squeakfoundation.org/pipermail/cryptography/2006-January/000117.html Not much to it but we got a lot of advice from SFLC first. >From our research OS projects are allowed to host cryptographic code and make available for anyone to download. BUT that does not exclude users of the code from being restrained from exporting that code to any USA identified restricted entities. For example: http://www.state.gov/j/ct/list/c14151.htm I would recommend at the very least to register the repo with the BIS for Pharo, but I would also contact the SFLC to verify nothing has changed.

Thank you for you research and advise on how to make it right, Ron. I
may look into it, but I don't want to promise you that I will definitely. I will certainly put this in my crypto folder, though. :) ... ^^ robert On 10/19/2015 06:25 PM, Ron Teitelbaum wrote: > Hi Robert, > > I went back and reviewed and this is what I sent to BIS. > > http://lists.squeakfoundation.org/pipermail/cryptography/2006-January/000117.html > > Not much to it but we got a lot of advice from SFLC first. > >>From our research OS projects are allowed to host cryptographic code and make available for anyone to download.

Thank you Ron, I'll look into it.

Hi Tim,

I think we long ago passed the point where more than 50% of all >32bit cpus were ARM. You are of course right. Possibly when I first read about "Digital Thermal Sensor", things may have been different. But I'm sure everyone knew what I meant. >Typically the temperature of each core is monitored by stuff added around the ARM cores in an SoC, not the ARM itself. For example on a Pi, `vcgencmd measure_temp` works, though strictly speaking that measures the general temp of the SoC - which like many devices that are ARM powered is a large thing to do stuff and just happens to have a few Gips of processor hidden in a small corner. >tim Exactly what temperature is being measured probably doesn't matter as long as there is enough range to help add some entropy.
