Function casper_client::sign_deploy_file

pub fn sign_deploy_file<P: AsRef<Path>>(
    input_path: P,
    secret_key: &SecretKey,
    output: OutputKind<'_>
) -> Result<(), Error>

Reads a previously-saved Deploy from a file, cryptographically signs it, and outputs it to a file or stdout.

output specifies the output file and corresponding overwrite behaviour, or if OutputKind::Stdout, causes the Deploy to be printed stdout.

The same path can be specified for input and output, and if the operation fails, the original input file will be left unmodified.
