Aleph.im message specification

Project description

Aleph.im Message Specification

This library aims to provide an easy way to create, update and manipulate messages from Aleph.im.

It mainly consists in pydantic models that provide field type validation and IDE autocompletion for messages.

This library provides:

  • schema validation when parsing messages.
  • cryptographic hash validation that the item_hash matches the content of the message.
  • type validation using type checkers such as mypy in development environments.
  • autocompletion support in development editors.

The item_hash is commonly used as unique message identifier on Aleph.im.

Cryptographic signatures are out of scope of this library and part of the aleph-sdk-python project, due to their extended scope and dependency on cryptographic libraries.

This library is used in both client and node software of Aleph.im.

Usage

pip install aleph-message
import requests
from aleph_message import parse_message
from pydantic import ValidationError

ALEPH_API_SERVER = "https://official.aleph.cloud"
MESSAGE_ITEM_HASH = "9b21eb870d01bf64d23e1d4475e342c8f958fcd544adc37db07d8281da070b00"

message_dict = requests.get(ALEPH_API_SERVER + "/api/v0/messages.json?hashes=" + MESSAGE_ITEM_HASH).json()

try:
    message = parse_message(message_dict["messages"][0])
    print(message.sender)
except ValidationError as e:
    print(e.json(indent=4))
