Issue installing cryptography on Raspberry Pi 2B (armv7h Arch Linux ARM) (python 3.9.8)

Asked 2022-Feb-05 at 19:41

I'm having some trouble installing the python cryptography package on my raspberry pi, specifically with python version 3.9.8 (installed with pyenv). The cryptography package is installed on my system using pacman (python-cryptography package), and thus works using the main python interpreter (3.10.1). However, I need some version of python 3.9 specifically for another package I am using in this project. Any time I try to install cryptography through the python 3.9.8 environment, I get the following error:

ANSWER

Answered 2022-Jan-14 at 19:59

@jakub's solution ended up solving the problem for me. I uninstalled the version of rust that was installed through pacman. To replace it, I installed rustup and then using rustup, installed the latest nightly version of rust (1.60). Once I did that, installing the cryptography package worked just fine.

If you are using rustup, just make sure that you add ~/.cargo/bin to your PATH before installation. Also, the command I used to install rust through rustup was rustup toolchain install nightly.

Spring Cloud gateway has filters to modify request body and response body.

ModifyResponseBody
ModifyRequestBody

As mentioned in the specs, for using these filters, we need to use DSL approach rather than YAML file for configuring routes. So essentially you will have a RouteBuilder like below -

Is there a better way to Optimize code that takes one value out of a Request body, the data comes in, in json format

Asked 2021-Dec-13 at 18:03

I have an request object, that contains a huge amount of data. But there is a filter in my code, where I need to take out just one element. At the moment I am Deserializing the whole object, which seems overkill to just get one element

This is part of a zuul filter

Answered 2021-Dec-13 at 17:11

At it's simplest the request payload can just be a string so you could read the input as a string and then parse what you want out using a regular expression or an indexOf or whatever suits best?

Suggestion for microservices security spring boot

Asked 2021-Nov-25 at 13:48

I want to create a project with spring boot, based on microservices. I implemented a gateway with Zuul and now not sure what to use for the security between microservices. I need the microservices to be aware of the user's permissions when they get a request, also they might communicate with each other, not only gateway. I am using spring boot 2.5.7 , but seems that oauth2 is deprecated, I also read about spring authorization server, but it is is experimental. What should i use for security and also if you have some tutorials will be great.

P.S. It will help a free solution, even if it means more implementation.

Thank you.

What if you do your security only at gateway layer ? and keep your micro-services without security ? Not sure if will fit your requirements.

Check this example using AWS gateway + cognito, same idea:
