# 🚀 Cross Crypto Py 🐍🔒
   
**Encriptación híbrida segura entre Python, TypeScript y Rust (AES-GCM + RSA-OAEP)**
---
## 📌 Introducción
**Cross Crypto Py** es una librería de encriptación híbrida que combina **AES-GCM** para cifrado simétrico y **RSA-OAEP** para intercambio seguro de claves. Su ventaja clave es la **interoperabilidad total** entre Python, JavaScript/TypeScript y Rust.
> Cifra datos en un lenguaje y descífralos en otro, con soporte para JSON, objetos serializados (`dill`) y archivos binarios (`PDF`, imágenes, etc).
---
## 🛠️ Uso básico (modo JSON)
```python
from cross_crypto_py.keygen import generateRSAKeys
from cross_crypto_py.encrypt import encryptHybrid
from cross_crypto_py.decrypt import decryptHybrid
# 🔑 Generar claves RSA
keys = generateRSAKeys()
publicKey = keys["publicKey"]
privateKey = keys["privateKey"]
# 📩 Datos simples
data = { "mensaje": "Hola AcaDyne desde Python" }
# 🔒 Encriptar con modo JSON (por defecto)
encrypted = encryptHybrid(data, publicKey)
print("🛡️ Encriptado:", encrypted)
# 🔓 Desencriptar
decrypted = decryptHybrid(encrypted, privateKey)
print("✅ Desencriptado:", decrypted)
```
---
## 💡 Uso avanzado
### 🔹 Objetos complejos (`mode="dill"`)
```python
from cross_crypto_py.encrypt import encryptHybrid
from cross_crypto_py.decrypt import decryptHybrid
objeto_complejo = {"clase": MiClase(), "config": {"x": 1}}
encrypted = encryptHybrid(objeto_complejo, publicKey, mode="dill")
decrypted = decryptHybrid(encrypted, privateKey, mode="dill")
```
### 🔸 Archivos binarios (`mode="binary"`)
```python
with open("imagen.png", "rb") as f:
contenido = f.read()
encrypted = encryptHybrid(contenido, publicKey, mode="binary")
decrypted = decryptHybrid(encrypted, privateKey, mode="binary")
with open("imagen_recuperada.png", "wb") as f:
f.write(decrypted)
```
---
## 📁 Cifrado híbrido de archivos (`encryptFileHybrid`)
```python
from cross_crypto_py.file_crypto import encryptFileHybrid, decryptFileHybrid
# 🔒 Encriptar uno o varios archivos/carpetas como ZIP
encrypted = encryptFileHybrid(
paths=["datos/", "documento.pdf"],
public_key=publicKey,
save_file=True,
output_enc="datos.enc"
)
# 🔓 Desencriptar archivo .enc y extraer archivos ZIP
output_dir = decryptFileHybrid("datos.enc", privateKey)
print("Archivos restaurados en:", output_dir)
```
---
## 🧬 Modo streaming para archivos grandes
```python
# Encriptar archivo grande (streaming)
encrypted = encryptHybrid("video.mp4", publicKey, stream=True)
# Desencriptar archivo grande (streaming)
output_path = decryptHybrid(
encrypted,
privateKey,
stream=True,
decrypted_output_path="video_restaurado.mp4"
)
```
> ✅ Este modo evita cargar el archivo completo en memoria. Ideal para videos, backups, etc.
