Encryption¤

Encryption requires an encryption key or user password, from which the encryption key will be generated. When using encryption with a password, you must choose an arbitrary seed to create the salt.

You can generate a random key

Example

from redast import Encryption

secret = Encryption.generate_key()
print(secret)

Generating an encryption key using a passphrase¤

Example

from redast import Encryption

secret1 = Encryption.generate_key(password="mypassword", seed=2022)
secret2 = Encryption.generate_key(password="mypassword", seed=2022)
secret3 = Encryption.generate_key(password="mypassword", seed=2021)
print(secret1, secret2, secret3, sep="\n")

Encryption with an encryption key¤

Example

from redast import Storage, Memory, Encryption

storage = Storage(Memory())


secret = Encryption.generate_key()
key = storage.encryption(key=secret).push(b"topsecret")

encrypted = storage.load(key)
decrypted = storage.encryption(key=secret).load(key)

print(encrypted, decrypted, sep="\n")

b"\x00k\xd0=\x81\xedh\x94x\xed\xb0\x14\xe3\r\x96'"
b'topsecret'

Encryption with a password¤

Example

from redast import Storage, Memory

storage = Storage(Memory())

key = storage.encryption(password="mypassword", seed=10).push(b"topsecret")

encrypted = storage.load(key)
decrypted = storage.encryption(password="mypassword", seed=10).load(key)

print(encrypted, decrypted, sep="\n")

b'\xe4\xc6\x0bc\xd0\x92\xcb\xaeQ\x0ey&\x83\xb9\x9d@'
b'topsecret'
