  -i, --input-file <INPUT_FILE>    input file
  -o, --output-file <OUTPUT_FILE>  output file
      --sum-codes <SUM_CODES>      separated by colon ":" paths to key_path:nonce_path files that will be merged into codes file
      --codes-file <CODES_FILE>    codes from one file in format: key=xxx nonce=yyy
      --display-codes              display codes loaded from file using --codes-file flag and then exit
  -r                               random key and nonce
      --save-codes                 save key and nonce to separete codes file
