enciphers 0.1.0

Fast encryption library with Rust-powered Python bindings

enciphers

Fast Rust-powered encryption for Python.

Benchmark

Tested on 1000 iterations. enciphers uses Rust bindings. Fernet and itsdangerous are pure Python. rfernet uses Rust bindings (Fernet algorithm).

	enciphers	Fernet	rfernet	itsdangerous
encrypt (ms)	0.45ms	10.42ms	2.68ms	11.96ms
decrypt (ms)	0.41ms	9.12ms	1.69ms	9.15ms
memory enc (B)	176	1330	225	383,391
memory dec (B)	99	830	99	59,594
encrypts data	✅	✅	✅	❌ signs only
algorithm	Substitution + HMAC-SHA256	AES-128-CBC	AES-128-CBC	HMAC

Note: enciphers uses a custom substitution cipher optimized for speed. It is not a standard cryptographic algorithm and is not recommended for highly sensitive data. Suitable for session tokens and non-critical data.

Features

• Fast — up to 95% faster than Fernet in Python
• Lightweight — minimal memory footprint
• Simple API — two methods: encrypt and decrypt
• Unique tokens — same input produces different output every time
• Signed — HMAC-SHA256 on every token

Installation

pip install enciphers

Usage

import orjson
from enciphers import Encipher

cipher = Encipher(step=7, key=42)
# or from environment variable
cipher = Encipher(step=7, key_env="CIPHER_KEY")

token = cipher.encrypt(orjson.dumps({"id": "1", "name": "mejlad"}))
data  = orjson.loads(cipher.decrypt(token))

Parameters

Parameter	Type	Description
step	int	Encryption step (required)
key	int	Secret key (takes priority over key_env)
key_env	str	Environment variable name for the key

At least one of key or key_env must be provided.
