# Executor Runtime
This directory contains implementations of executor's runtime. The executor
runtime provides interfaces (I/O) between executors (in trusted execution
environment) and external components (in untrusted world like file system). The
interfaces are defined in the TeaclaveRuntime
traits. Currently, we have two
runtime implementations: DefaultRuntime
and RawIoRuntime
. By default,
Teaclave provides a runtime called DefaultRuntime
, which bridges interfaces to
our secure file system implementation (i.e., protected file). While
RawIoRuntime
is only for debugging, which does not encrypt any I/O.
