QUESTION
I need to edit the python request to add TLS settings (by TLS settings I mean tls finger printing int, ja3).
...ANSWER
Answered 2022-Jan-11 at 21:19The JA3 fingerprint is based on ciphers and order and various TLS extensions and order. While ciphers and order can be changed features like the TLS extension order are not accessible from Python. This means there is no way to emulate a specific JA3 fingerprint from Python and thus also not from requests.

with join. pd.concat the merges for each column and join to your original df1. fillna the count columns with 0 as shown in the expected output.
QUESTION
I am trying to use the openssl api to implement the JA3 method (TLS fingerprinting method) on a personnal project. To do that I need to get some informations on the Client Hello packet and I am trying to do that with the openssl api https://www.openssl.org/docs/man1.1.1/man3/ . Firstly I downloaded a code which set up a TLS connection between my computer and a website and retrieved the certificat information. This program is running well, the tls connection is using TLS 1.3 and the certificat information are ok. Then I tried to retrieved the Client Hello packet to start implement the JA3 method. After few researches I found many function that may allow me to get the information I need : https://www.openssl.org/docs/man1.1.1/man3/SSL_client_hello_cb_fn.html . All of those function can only be call on the client hello callback function. This function can be called thanks to the SSL_CTX_set_client_hello_cb function. But in my case my function is never called. I am starting to be hopeless it's why I need your help. I really searched a lot to debug that but I didn't find a flag that can allow the callback function or something like that. Here is the program :
...ANSWER
Answered 2021-Mar-16 at 16:20The hint for what is going wrong is from the first line of the description in the doc that you linked to:
SSL_CTX_set_client_hello_cb() sets the callback function, which is automatically called during the early stages of ClientHello processing on the server.
This is called by a server when processing the received ClientHello. You have written a client and therefore it is never called.
As an alternative I suggest you look at SSL_CTX_set_msg_callback():
https://www.openssl.org/docs/man1.1.1/man3/SSL_CTX_set_msg_callback.html
From the docs:
SSL_CTX_set_msg_callback() or SSL_set_msg_callback() can be used to define a message callback function cb for observing all SSL/TLS protocol messages (such as handshake messages) that are received or sent, as well as other events that occur during processing.
QUESTION
before i got this problem i used redux, there this problem didnt occur. Now where i switched my approach i encountered this issue.
On my Homepage i decided to fetch the data i need and store it in the sessionStorage, then when the user clicks on a product is getting redirected to a template where i simply want to fill in the values.
Whenever i enter the Object like data.title i get undefined (I know its because useEffect runs after the render cycle). How i should proceed here?
Either i pick the values from the sessionStorage or i fetch it, please see my code for useEffect:

Answered 2020-Oct-19 at 21:55If I understood correctly, your problem is about trying to use an object that isn't defined just yet. If this is the case, my suggestion would be something like:

I'm trying to upload a new line JSON to Elasticsearch using the Bulk API. The bulk JSON I'm uploading looks like this, with each JSON on a new line:

QUESTION
I'm trying to make multiple API calls to retrieve JSON files. The JSONs all follow the same schema. I want to merge all the JSON files together as one file so I can do two things:
1) Extract all the IP addresses from the JSON to work with later 2) Convert the JSON into a Pandas Dataframe
When I first wrote the code, I made a single request and it returned a JSON that I could work with. Now I have used a for loop to collect multiple JSONs and append them to a list called results_list so that the next JSON does not overwrite the previous one I requested.
Here's the code

Install ja3
You can use ja3 like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
