Setting private key

please creata defi-entities/private.rs with following context

pub const KEY_ENCRYPTION_PWD: [u8; 16] = [35, 48, 129, 101, 133, 220, 104, 197, 183, 159, 203, 89, 168, 201, 91, 130];

To change key encryption password run

cargo run --bin keys generate-password  

To get encrypted key run:

cargo run --bin keys encrypt --key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

Starting loom

DATA=<ENCRYPTED_PRIVATE_KEY> cargo run --bin loom
