Encryption using 2 Factor Authentication through an external drive with Python

physical2fa's Issues

ValueError: Fernet key must be 32 url-safe base64-encoded bytes.

Hi,

The fail_safe.py file works fine for me, but the other thing doesn't. It's actually two problems.

The first one to decrypt (USB, on D disk, NTFS formatted):

None
Traceback (most recent call last):
  File "lock.py", line 1, in <module>
    from Physical2FA import decrypt
  File "C:\Python38-32\lib\site-packages\Physical2FA\decrypt.py", line 47, in <module>
    decrypt(i, pubkey)
  File "C:\Python38-32\lib\site-packages\Physical2FA\decrypt.py", line 31, in decrypt
    f = Fernet(key)
  File "C:\Python38-32\lib\site-packages\cryptography\fernet.py", line 37, in __init__
    raise ValueError(
ValueError: Fernet key must be 32 url-safe base64-encoded bytes.

The second for encryption (USB, on D-disk, formatted in FAT32):
*With files in the root it works, but with folders ('bb') I get the following error.

lock.py
you will encrypt the following files: ['aa', 'bb', 'key.key', 'lock.py', 'System Volume Information', 'WhatsAppImage.png']. Are you sure you want to continue? y/n: y
['aa', 'bb', 'key.key', 'lock.py', 'System Volume Information', 'WhatsAppImage.png']

['a.png', 'b.png', 'c.png', 'd.png', 'e.png', 'f.png', 'g.png']

    os.chdir(i)
FileNotFoundError: [WinError 2] El sistema no puede encontrar el archivo especificado: 'bb'

Could you give me an idea of what I might be doing wrong? Thanks

I have performed the following steps:

• First execution:

from Physical2FA import write_key
write_key

• Second execution:

from Physical2FA import encrypt
encrypt

• Third execution:

from Physical2FA import decrypt
decrypt
