encryptiontools pypi

Ferramentas de criptografia para Python 3

Ferramentas para criptografia e descriptografia, assinatura e verificação. Use criptografia simétrica e assimétrica (baseada em RSA).

Instalação

 pip install encryptiontools

Uso

Criptografia e descriptografia assimétricas

 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'

Criptografia e descriptografia simétricos

 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'

Criptografia e descriptografia combinados

O par de teclas assimétricas é usado para criptografar/descriptografar a chave interna (simétrica), a chave interna é usada para descriptografar dados.

 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'

Assinatura e verificação

 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
