CryptSync is shipped with GnuPG v1.4.9, which uses Cast5 by default (CryptSync doesn't change that).

The most straightforward way would be to change CryptSync's source code yourself and compile a personal version. (Build instructions are very clear, I tried it before)

The relevant source code is in "FolderSync.cpp", line 941 and line 1009
