cryptiq 0.1.0

A modern cryptography utilities library for Python, providing ergonomic primitives for key management, encryption, hashing, signatures, tokens, and secret handling.

cryptiq

A lightweight, backend-agnostic cryptography abstraction layer for Python.

Overview

cryptiq provides a unified and strongly-typed interface over multiple cryptography backends.

It focuses on consistency, composability, and safe defaults while allowing flexibility between implementations such as cryptography and pycryptodome.

---

Features

• Backend-agnostic cryptographic API
• RSA key generation and loading
• Unified encryption/decryption interface
• Strong typing with overload-safe APIs
• Support for multiple key formats (PEM/bytes/string)
• Pluggable backend system (cryptography, pycryptodome)
• Clean separation of crypto logic and type definitions

---

Installation

Using uv:

uv add cryptiq

Or pip:

pip install cryptiq

---

Usage

Key Generation

from cryptiq.enums import Backend
from cryptiq.rsa import generate_private

keypair = generate_private(Backend.CRYPTOGRAPHY)

---

Loading Keys

from cryptiq.keys import load_private
from cryptiq.enums import Backend

key = load_private(
    Backend.CRYPTOGRAPHY,
    path="private.pem",
    password=None,
)

---

Encryption

from cryptiq.rsa import encrypt
from cryptiq.enums import Backend

ciphertext = encrypt(
    key,
    "hello world"
)

---

Bytes Mode

ciphertext = encrypt(key, b"hello world")

---

Design Philosophy

cryptiq follows these principles:

• Backend abstraction without leaking implementation details
• Strong typing with explicit overloads
• Consistent input/output behavior across APIs
• Prefer safe defaults over flexible ambiguity
• Keep crypto primitives simple and composable

---

Non-goals

cryptiq does NOT aim to:

• Replace full-featured crypto libraries like cryptography
• Implement low-level cryptographic primitives from scratch
• Provide opinionated security policies (key storage, rotation, etc.)
• Become a framework-level security system
• Hide cryptographic behavior behind excessive abstraction

---

Architecture Notes

cryptiq is built around a backend dispatch model:

• Backend enum selects implementation
• Each backend returns its native key types
• Public APIs normalize behavior through typed unions and overloads

This allows flexibility while keeping a consistent external API surface.
