As an aside, I just prepared a branch of SQLCipher for Android that will
allow for statically linking libcrypto from OpenSSL.  The versions of
libcrypto shipping with Android vary, and sometimes are rather old.  This
script allows us to use the OpenSSL git repository and build from source,
currently using the latest 1.0.1e tag by targeting a stand alone toolchain
from the NDK.  This script to assemble the static libraries is here:
