📗SpiderCrypt API Documentation

Description

Welcome . In this doc you gonna learn how to use SpiderCrypt API for data security. It provides robust functionalities for encryption, decryption, hashing, signing, and verifying data, using shared authentication keys and user identifiers to ensure traceability and security for developers ,SME,individuals .

---

Classes and Methods

Class SpiderCrypt

This class is the core of the SpiderCrypt API and enables all the main cryptographic operations.

Initialization

SpiderCrypt(secret_key: str)

• Parameter:

  • secret_key: Shared secret key used to initialize the class. It is required for all secure operations.

---

Main Methods

encrypt

encrypt(data: str, auth_key: str) -> bytes

• Description: Encrypts sensitive data.

• Parameters:

  • data: Data to encrypt (string).

  • auth_key: Authentication key used for this operation.

• Returns: Encrypted data as bytes.

---

decrypt

decrypt(encrypted_data: bytes, auth_key: str) -> str

• Description: Decrypts previously encrypted data.

• Parameters:

  • encrypted_data: Encrypted data (as bytes).

  • auth_key: Authentication key used for this operation.

• Returns: Decrypted data as a string.

---

hash_data

hash_data(data: str, auth_key: str) -> bytes

• Description: Creates a unique hash of the data to ensure its integrity.

• Parameters:

  • data: Data to hash (string).

  • auth_key: Authentication key used for this operation.

• Returns: Hashed value as bytes.

---

sign_data

sign_data(data: str, auth_key: str) -> bytes

• Description: Generates a digital signature of the data to ensure its authenticity.

• Parameters:

  • data: Data to sign (string).

  • auth_key: Authentication key used for this operation.

• Returns: Signature of the data as bytes.

---

verify_signature

verify_signature(data: str, signature: bytes, auth_key: str) -> bool

• Description: Verifies if the signature of the data is valid.

• Parameters:

  • data: Original data (string).

  • signature: Signature to verify (as bytes).

  • auth_key: Authentication key used for this operation.

• Returns: A boolean indicating if the signature is valid (True) or not (False).

---

Error Handling

PermissionError

Raised when authentication fails (e.g., if auth_key is incorrect).

Exception

Raised for any other non-specific errors (e.g., corrupted data or invalid format).

---

Example Usage

Here is a complete example of using the main features of the API:

from flask import Flask, request, jsonify
from spidercrypt import SpiderCrypt  # Import the SpiderCrypt library

app = Flask(__name__)

# Shared authentication key for security
auth_key = os.getenv('SECRET_KEY')  # Secure secret key


# Initialize SpiderCrypt with the secret key for secure operations
cipher = SpiderCrypt(secret_key=auth_key)

This API offers a comprehensive set of cybersecurity features for the protection of sensitive data. It is designed to be easy to integrate into any application that requires encryption, hashing, and digital signature operations.

The four implementations allow flexibility according to needs:

Python (Flask) : More complete with additional features like batch encryption and key generation.

Go (Gin) : Faster and lighter for environments requiring increased performance.

Ruby (Sinatra) : Simple and fast to deploy, ideal for small secure applications. -

Node.js (Express) : Suitable for web applications and services requiring fast processing in JavaScript.
