Subject: [crypto] set default case for key_type and avoid build warnings
X-Git-Tag: v0.8~150

[crypto] set default case for key_type and avoid build warnings

when key_type is unknown, gcc complains that cipher can be used
uninitialized.

add default case to catch wrong callers and avoid build warning
