Python 解码文件的密码学不起作用，出现两个错误块

Question

每次我尝试解密保存在文件中的密码并将其与输入的字符串（在解密和更改数据类型之后）进行比较时，都会出现解密错误。我尝试了很多代码和其他东西的组合，但它仍然会出现这个错误。我不知道该怎么办了，我真的需要一些帮助。

主要代码：

def login():
  from cryptography.fernet import Fernet

  file = open('key.key', 'rb')
  key = file.read()
  file.close()

  loginask = input('What is your username?')

  transf_loginask = 'login_list.' + str(loginask)

  if path.exists(loginask) == True:
    found = input('ACCOUNT FOUND! PLEASE INPUT PASSWORD:\n')
    file = open(loginask, 'rb+')
    pawo = file.readline()

    pawo = str(pawo, 'utf-8')
    pawo = bytes(pawo, 'utf-8')

    f = Fernet(key)
    pawo = f.decrypt(pawo)

    pawo = str(pawo, 'utf-8')

    if pawo == found:
      print('ACCESS GRANTED.')
      menu()
    else:
      print('ERROR, WRONG PASSWORD.')
      login()
  else:
    print('ACCOUNT NOT FOUND. PLEASE CHECK FOR SPELLING MISTAKES OR CREATE ONE.')



login()

加密后的密码（只有最上面的是密码）：

错误：

当您用于加密密码的密钥与用于解密的密钥不同时，就会出现该错误。
