commit 73ff075204df09db5248170a049f06498cdbb7aa
Author: Daniel Kahn Gillmor <dkg at fifthhorseman.net>

    gpg: default to AES-256.
    
    * g10/main.h (DEFAULT_CIPHER_ALGO): Prefer AES256 by default.

    It's 2017, and pretty much everyone has AES-256 available.  Symmetric
    crypto is also rarely the bottleneck (asymmetric crypto is much more
    expensive).  AES-256 provides some level of protection against
    large-scale decryption efforts, and longer key lengths provide a hedge
    against unforseen cryptanalysis.
