Brian:
Ahhh, ok, I get it. It’s easy to re-seed every time it’s called, using the
milliseconds. That assumes that the user of the program initiates the action at
a random time.
I’ll change the code so it re-seeds every time.

Bill

Skype also crashes. With Adobe AIR apps a current app crashes, but one from
four years ago doesn’t. Hopefully Apple will fix things.

Hello Andrew,
No we did not have a chance to look at it yet, but we are aware of the
issue. I think I had filed a bug report a week ago, I'll double check and
let you know.

Had my first customer complaint about the app not working on their
device running the iOS 12 beta. Luckily I was able to point to a blog
post about how Fortnite also crashes under iOS 12 and explained how
their development budget is WAY larger to buy some time ;)

Initial code is posted here:

I'll update it later today with an updated version of the PHP that uses a
different IV for the return data.

I think the IV vulnerability that I’m talking about is more theoretical than an
actual concern. From what I’ve read the attacker needs to be able to
control/influence what is being encrypted for knowledge of the next IV to help
(so they can use a known plain text to test their key hypothesis).
I haven’t spent the time to get familiar with github, but after I modify the
php to use a random iv for the return data, I’m happy with any way to
disseminate it for others.
I’ll post a new link, when I’m done. Probably later today. I will also remove
the link to my server. Then, I invite you
Brian,
Thank you for your wisdom on this issue. I’m very interested in your
recommendations and they are inspiring me to do more Internet research.
Just asking...
You said that the attacker could figure out the next iv. Since I append the iv
to the front of the encrypted data, the attacker will
I’ll volunteer to add it to my community repo if desired.

Good suggestion.
Easy-peasy. Php has a nice function to generate random iv vectors, so I’ll put
it in. Thanks for the suggestion!

Hi Brian,
I think it would be pretty hard to do based on the time.
One would have to do the calculation in advance and
hope that the program caught the server at exactly
the correct millisecond. As you also pointed out the
hacker would also have to have access to the code.
If you generate your o
I just put the PHP on my server and it was able to handle the randombytes IV
without issue.
The demo does not generate a new IV for the returned data which it really
should in production.
From a security perspective, you assume that an attacker has access to the
code. From the encrypted messag
