Autocrypt - Wikipedia

Just reading in-depth and trying to understand the security model of Delta.Chat a bit more… There’s a few things that really concern me about how Delta.Chat which relies on Autocrypt work:

• There is no Perfect Forward Secrecy
  
• No verification of keys
  
  • Is therefore susceptible to Man-in-the-Middle attacks
    
• Metadata is a BIG problem with Delta.Chat:
  
  • The To and From and Date are trackable by your Mail provider (amongst many other headers)

This pep proposes to allow parentheses surrounding the two-subject form of
assert statements. This will cause the interpreter to reinterpret what before
would have been an assert with a two-element tuple that will always be True

failure message, equivalent to the statement with the parentheses removed
