hello-message-sdk 0.2.0

A Python SDK for AI agents to securely generate and verify 'hello' authentication messages, enabling seamless interaction between AI agents and AI-centric services.

Hello-Message Python SDK

The Hello-Message Python SDK provides a simple interface for generating and verifying "hello" authentication messages for AI-to-AI and AI-to-AI-first services. This SDK is designed to work by using cryptographic signatures for secure authentication.

---

Installation

Install the SDK from PyPI using pip:

pip install hello-message-sdk

---

Features

• Generate Hello Messages: Create signed "hello" messages using Ethereum private keys.
• Verify Signatures: Validate the authenticity of signed "hello" messages.

---

Quick Start

Generate a "Hello" Message

from hello_message import Hello

# Initialize the Hello SDK with a private key
private_key = "<your_ethereum_private_key>"
hello = Hello(private_key=private_key)

# Get the Ethereum address
address = hello.get_address()
print("Address:", address)

# Generate a signed "hello" message
hello_message = hello.generate_hello_message()
print("Hello Message:", hello_message)

Verify a "Hello" Message

from hello_message import Hello

# Example signature and address
signature = "<signature_from_hello_message>"
address = "<ethereum_address>"

# Verify the signature
is_valid = Hello.verify_signature(hello_message["signature"], hello_message["message"], address)
print("Is valid:", is_valid)

API Reference

Class: Hello

Hello(private_key: str)

Initialize the Hello object with an Ethereum private key.

• private_key: Ethereum private key (string) used for signing messages.

get_address() -> str

Get the Ethereum address corresponding to the private key.

generate_hello_message() -> dict

Generate a signed "hello" message.

verify_signature(signature: str, message: str, address: str) -> bool

Verify the authenticity of a "hello" message signature.

• signature: The signed "hello" message (string).
• message: The message to verify (string).
• address: The Ethereum address expected to have signed the message (string).

Returns:

• True if the signature is valid.
• False otherwise.

Testing

Run the tests using pytest:

python -m pytest
