cryptography reviews and mentions

• “Our paying customers need X, when will you fix it?”

  Some context:

  - The cryptography dependency used by the current release of mitmproxy has a CVE related to an OpenSSL vulnerability (https://github.com/pyca/cryptography/security/advisories/GHS...)

  - The main branch of mitmproxy has already upgraded to the latest version of the cryptography package

  - The author of the package does not believe the CVE impacts users of mitmproxy so a release including this commit has not been made

• Microservice memory profiling
  2 projects | /r/FastAPI | 28 May 2023

  first, I did see a correlation between an endpoint being heavily hit in a given time window, and an increase of memory usage that didn't went down afterwards. The endpoint didn't do much so I went through every instruction - is a global variable appended indefinitely ? Is a cache decorator growing without a limit set ? Do I use a 3rd party that has a known issue ? Turns out, it was using cryptography, so I looked up known issues. Saw an issue about a leak when using load_pem_x509_certificate https://github.com/pyca/cryptography/issues/4833 - which I used ! I could fortunately just upgrade the library

• I love building a startup in Rust. I wouldn't pick it again

  > A big problem with Rust, long-term, is that the kind of programs that really need it are somewhat out of today's mainstream. It's not that useful for webcrap. It's not that useful for phone apps. The AI people use Jupyter notebooks and Python to drive code on GPUs.

  One thing this is missing is that Rust is useful for libraries callable by many different languages. You may or may not want to use it to build an actual Web app (I personally think it's a solid choice, but reasonable people can disagree). But for building, say, the Python cryptography library [1], which is used as a part of "webcrap" and Jupyter notebooks, Rust is clearly an excellent option. Nobody is going to build core Python infrastructure in Go or Node, and there will always be a need for plumbing libraries.

  > I am curious. Could you give some more context?

  Probably talking about this: https://github.com/pyca/cryptography/issues/5771

• Using a src directory for a Python package

  As for an example, cryptography is the general example I recommend here: https://github.com/pyca/cryptography

• Difference between ruby 2 and ruby 3?

  Wasn't entirely serious, just this crap https://github.com/pyca/cryptography/issues/5771

• OpenSSL Security Advisory [5 July 2022]
  6 projects | news.ycombinator.com | 5 Jul 2022

  The modes of operation aren't the main reason people use OpenSSL; it's the support for all the gnarly (and less gnarly) protocols and wire formats that show up when doing applied cryptography.

  Progress is being made on replacing OpenSSL in a lot of contexts (specifically, the RustCrypto[1] folks are doing excellent work and so is cryptography[2]), but there are still plenty of areas where OpenSSL is needed to compose the mostly algebraic cryptography with the right wire format.

• Help with basic steps in an application design

  2) Which cryptographic library would be recommended for this purpose? I've seen people using PyCrypto (https://github.com/pycrypto/pycrypto) which seems simple enough, but that one seems not maintained anymore. I've also seen keyring.cryptfile (https://github.com/frispete/keyrings.cryptfile) and pyca/cryptography (https://github.com/pyca/cryptography) but I'm not really sure if any of those should actually be used for my purpose?

• I made the prepper version of the Internet
  6 projects | /r/preppers | 28 Mar 2022

  Ah, and sorry, I forgot, I don't use any third party libs for the networking. It's all from scratch to be as efficient as possible, and usable over low-bandwidth links. I used a library for fetching network card details when using physical ethernet devices as interfaces, and I used the very well-regarde cryptography.io library for the cryptographic primitives that I use in the implementation.
