Nice theorethical Talk. Will be reading a lot of the books...

Very disappointed. The history and older chypering technica are interesting to know, but the only link to php where 3 links after the talk.
Also did the speaker anounce not to do it your self.

For a talk of 45 minutes, spending 15 minutes on the history is quite long. Maybe for this conference it would have been cool to go in to phpencrypt a little more.

Good overview. I would've loved to hear more about the algorithms themselves, but maybe that's not for everyone.

Well structured talk with an interesting summary of historical basis and finishing off with enough about modern cyphers to whet the appetite, without going off the deep end.

Great talk. Lot's of easy to understand information about a difficult subject! Many detailed explanations about the history and evolution of cryptography. Very interesting.

I enjoyed the talk, i also liked the amount of history in it as to know where we are going with cryptography we should no where we come from.

Overall I though it was great. Lost me a little at some of the more mathematical illustrations, but the graphics did help improve my understanding. I thought it was a good balance of historic vs modern ciphers to be honest; it's important to have a solid understanding of these first, and not everyone does.

Very clear and technical talk about the history and present state of cryptography. All the way back to the ancient Substitution ciphers through the Caesar cipher and the workings of the Enigma Machine to the current methods used to encrypt/authenticate data. If you're interested in the theory of it all, this talk is very useful. But, as is said in the talk, if you do not know what you're doing, don't implement these things yourself, so there is no real practical knowledge transferred.

For me, I knew most of these ciphers and techniques, so there was no new information to gather ^^. However, it was a clear and structural explanation of the evolution and reasoning behind these techniques. And because I knew these techniques from before and haven't had much to do with them for the last few years, I was able to notice that his explanation made sense, and made me remember my colleges about these subjects (may be a bit mathematical for most tho maybe ;))

Nevertheless, great talk!

This is a nice subject but really hard to explain.
By adding a bit of history you made it more approachable. I liked the examples that you used, but I did get a little lost with your first diagram.
I think it would benefit if you added some animations illustrating the behavior of an algorithm or added some extra slides explaining the symbols used in the diagrams. (I personally got distracted trying to understand the diagram of the A5/1 implementation and as a consequence didn't pay attention to what you were saying)

Though I personally liked seeing a bit of math, I think you should skip the notation and just show a simple example of how the equations are used.

Good speaker, excellent content. Too bad there wasn't enough time to go in deeper. Not trying to force PHP in the mix felt like a breath of fresh air to me! Keep it up!

Loved the history of ciphers and how some of them were compromised.
However, I missed some more insight in which are supported in (vanilla) PHP today and which are trustworthy.
