Hashing and parsing

Verification step for application that states this

Send a GET request to https://api.close.com/buildwithus/  Follow the instructions provided in the response. Enter your Verification ID in the space provided here.

Using the GET request to that url you get the following for example

{
    "traits": [
        "Craftsman",
        "Pragmatic",
        "Curious",
        "Methodical",
        "Driven",
        "Collaborator"
    ],
    "key": "Close-9bae741a",
    "meta": {
        "description": "Enclosed are some traits that [Joe](https://www.linkedin.com/in/jkemp101/) believes great engineers exhibit. Using the included UTF-8 `key`, construct a JSON array using the lowercase hex digest of the blake2b hash for each trait (digest size=64). POST this bare array back to this endpoint. Example array: [\"1f9ec19c7...57fd27e5\", \"79c72b47088...bf13026c\", ...] If the hashes are correct you will get a Verification ID you should include in your application. 400 responses indicate a problem with the hashes in your array. Note, the key rotates each day around midnight EST."
    }
}

First off you can compute with an online tool here BLAKE2b, but can also work it out with Python like so:

from hashlib import blake2b
import httpx
from icecream import ic

def hash_input(input_data: str, key: str, encoding_type ='utf-8') -> str:
    key_bytes = key.encode(encoding_type)
    to_hash = input_data.encode(encoding_type)
    return blake2b(to_hash, key=key_bytes).hexdigest()



if __name__ == "__main__":
    endpoint_url = "https://api.close.com/buildwithus/";
    data = (httpx.get(endpoint_url)).json()
    hash_results = ic([hash_input(input, data['key']) for input in data['traits']])
    response = httpx.post(endpoint_url, json=hash_results)
    ic((response.content.decode("utf-8")).strip().split(":").pop().strip())
