I am getting this error when I am decrypting the encrypted message.I fetched the the encrypted message from the db in django views as pw = donator.objects.filter(emai=email).values('passw')and passed the pw object in the decrypt_message() function.
The decrypt_messag() function is :
def decrypt_message(encrypted_message,key):
"""
Decrypts an encrypted message
"""
f = Fernet(key)
decrypted_message = f.decrypt(encrypted_message)
return decrypted_message.decode()
The error message is:
File "C:\Users\Neelesh Singh\workspace\BookHouse\donatorapp\views.py", line 129, in decrypt_message
f = Fernet(key)
File "C:\Users\Neelesh Singh\AppData\Local\Programs\Python\Python39\lib\site-packages\cryptography\fernet.py", line 37, in __init__
key = base64.urlsafe_b64decode(key)

raise TypeError("argument should be a bytes-like object or ASCII "
TypeError: argument should be a bytes-like object or ASCII string, not 'dict'
You should pass the item associated with passw to the function, so:
pws = donator.objects.filter(emai=email).values('passw')
for pw in pws:
# use pw['passw'], not pw ↓
decrypt_message(encrypted_message, pw['passw'])
