  1. doc: remove faulty justification for 128-bit AES

    This sentence implies that AES-128 is preferred over AES-256 because
    of a related-key attack from 2009. However, that attack by Alex
    Biryukov, Orr Dunkelman, Nathan Keller, Dmitry Khovratovich, and Adi
    Shamir, while impressive, is only effective against variants of
    AES-256 with a reduced number of rounds and it requires related keys.
    This means that the attack is not effective against AES-256 as it is
    used within TLS.
    
    (AES-128 is still often preferred over AES-256 simply because it is
    believed to be sufficiently secure and because it is faster.)
