Function main

ciphercore-base/src/bin/ciphercore_evaluate.rs:40–71

This binary evaluates a given context over the provided inputs using a simple evaluator. For a secret-shared output, output is revealed if the `reveal_output` boolean binary argument is set to `true`. # Arguments `context_path` - path to a serialized context `inputs_path` - path to serialized input(s) `reveal_output` - boolean to indicate if output is to be revealed # Usage < this_binary > [-
