Security for Humans
It is a thin layer on top of the cryptography module. Exposes an easy to use interface to EAS and RSA. Available on Pypi:
python3 -m pip install human_security
Symmetric encryption
The same key is used for encryption and decryption
from human_security import HumanAES
h = HumanAES()
h.generate()
saved_key = h.key
h = HumanAES()
h.key = saved_key
message = 'hello world'
encrypted = h.encrypt(message)
decrypted = h.decrypt(encrypted)
assert decrypted == message
Asymmetric encryption
A public key public_pem is used to encrypt and the corresponding private_pem is used for decryption
from human_security import HumanRSA
h = HumanRSA()
h.generate()
# save keys
public_pem = h.public_pem()
private_pem = h.private_pem()
# reload saved keys
h = HumanRSA()
h.load_public_pem(public_pem)
encrypted = h.encrypt(message)
h = HumanRSA()
h.load_private_pem(private_pem)
decrypted = h.decrypt(encrypted)
assert decrypted == message
Signatures
The public_pem is used to sign and the private_pem is used to verify the signature
from human_security import HumanRSA
h = HumanRSA()
h.load_private_pem(private_pem)
signature = h.sign(message)
h = HumanRSA()
h.load_public_pem(public_pem)
assert h.verify(message, signature)
