create session cookie

[Jish2]

Throw this code in it probably works

import json
import crypto
import boto3

# throw this in a helper folder or sum
def serialize_cookie(cookie_dict):
    cookie_string = ''
    for key, value in cookie_dict.items():
        cookie_string += f'{key}={value}; '
    
    return cookie_string.rstrip('; ')


secrets_manager_client = boto3.client('secretsmanager')

secret_name = 'resume-book-session-cookie-secret'

def lambda_handler(event, context):
    try:
        response = secrets_manager_client.get_secret_value(SecretId=secret_name)
        encryption_key = response['SecretString']
    except Exception as e:
        return {
            "statusCode": 500,
            "body": json.dumps("Error: Failed to retrieve encryption key")
        }

    user_data = ... # get username and password here
    serialized_user_data = json.dumps(user_data)

    cipher = crypto.Cipher(algorithm=crypto.Algorithms.AES, mode=crypto.Modes.CFB, key=encryption_key.encode(), iv=encryption_key.encode())
    encrypted_user_data = cipher.encrypt(serialized_user_data.encode()).hex()

    user_cookie = {
        "name": "userSession",
        "value": encrypted_user_data,
        "httpOnly": True,
        "max-age": 3600,
        "secure": True,
        "sameSite": "Lax"
    }

    serialized_cookie = serialize_cookie(user_cookie)

    response = {
        "statusCode": 200,
        "headers": {
            "Set-Cookie": serialized_cookie,
            "Content-Type": "text/plain"
        },
        "body": "Cookie has been set."
    }

    return response
