Herramientas de cifrado para Python 3

Herramientas para cifrado y descifrado, firma y verificación. Use el cifrado simétrico y asimétrico (basado en RSA).

Instalación

 pip install encryptiontools

Uso

Cifrado asimétrico y descifrado

 from encryptiontools . encryption import AsymmetricEncrypter , AsymmetricDecrypter
from encryptiontools . utils import generate_key_pair

public_key , private_key = generate_key_pair ( 512 )

data = { 'message' : 'hello asymmetric encryption' }

encrypter = AsymmetricEncrypter . create ( public_key . save_pkcs1 ())  # or AsymmetricEncrypter(public_key)
decrypter = AsymmetricDecrypter . create ( private_key . save_pkcs1 ())  # or AsymmetricDecrypter(private_key)

encrypted = encrypter . encrypt ( data )
decrypted = decrypter . decrypt ( encrypted )

assert decrypted [ 'message' ] == 'hello asymmetric encryption'

Cifrado simétrico y descifrado

 from encryptiontools . encryption import SymmetricEncrypter

key = b'0123456789abcdef'

data = { 'message' : 'hello symmetric encryption' }

encrypter = SymmetricEncrypter . create ( key )  # or SymmetricEncrypter(key)

encrypted = encrypter . encrypt ( data )
decrypted = encrypter . decrypt ( encrypted )

assert decrypted [ 'message' ] == 'hello symmetric encryption'

Cifrado combinado y descifrado

El par de claves asimétricas se usa para cifrar/descifrar la tecla interna (simétrica), la clave interna se usa para descifrar datos.

 from encryptiontools . encryption import CombinedEncrypter , CombinedDecrypter
from encryptiontools . utils import generate_key_pair

public_key , private_key = generate_key_pair ( 512 )

data = { 'message' : 'hello combined encryption' }

encrypter = CombinedEncrypter . create ( public_key . save_pkcs1 ())  # or CombinedEncrypter(public_key)
decrypter = CombinedDecrypter . create ( private_key . save_pkcs1 ())  # or CombinedDecrypter(private_key)

encrypted = encrypter . encrypt ( data )
decrypted = decrypter . decrypt ( encrypted )

assert decrypted [ 'message' ] == 'hello combined encryption'

Firma y verificación

 from encryptiontools . signature import Signer , Verifier
from encryptiontools . utils import generate_key_pair
from encryptiontools . exceptions import VerificationError

public_key , private_key = generate_key_pair ( 512 )

data = { 'message' : 'hello signing and verification' }

signer = Signer . create ( private_key . save_pkcs1 ())  # or Signer(private_key)
verifier = Verifier . create ( public_key . save_pkcs1 ())  # or Verifier(public_key)

signature = signer . sign ( data )

try :
  verifier . verify ( data , signature )
  assert True
except VerificationError :
  assert False
