There is decryption support for AES256 and we may eventually enable
AES256 for encryption.  Right now that is not possible because it would
break too many old installations.

With GnuPG 2.1 the s2k options are only used for --symmetric encryption.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
