crypto-capsule 0.0.2

Just a small script based on python cryptography and electrum mnemonics to encapsulate your secrets.

A convenience module for symmetric cryptography based on cryptography.fernet

Fernet library is in turn based on AES (128 bit) cryptography. More on that here: https://cryptography.io/en/latest/fernet/

Install

Reqruires:

• Python >= 3.8

Run install:

pip3 install crypto_capsule

Get started

from crypto_capsule import Key, Capsule

# derive a key from password
key = Key.from_password(b'Test me')

# encapsulate your secret
capsule = Capsule.create(key, b'This is a secret message')
print(capsule.open(key))

Use with mnemonics

from crypto_capsule import Key, Capsule

# create a new key (more secure than password)
key = Key.generate()

# print the key as a mnemonic phrase
print(key.to_mnemonic())


# encapsulate your secret
capsule = Capsule.create(key, b'This is a secret message')

# see what the capsule looks like as a mnemonic phrase
print(capsule.to_mnemonic())

# open the capsule with the key
print(capsule.open(key))

TODO

A client to manipulate files. A template for that is done in cli.py, and installed as crypt-capsule command. May be someone wants to extend that?
