Struct sc_cli::NodeKeyParams

pub struct NodeKeyParams {
    pub node_key: Option<String>,
    pub node_key_type: NodeKeyType,
    pub node_key_file: Option<PathBuf>,
}

Parameters used to create the NodeKeyConfig, which determines the keypair used for libp2p networking.

Fields

node_key: Option<String>

The secret key to use for libp2p networking. The value is a string that is parsed according to the choice of --node-key-type as follows: ed25519: The value is parsed as a hex-encoded Ed25519 32 byte secret key, i.e. 64 hex characters. The value of this option takes precedence over --node-key-file. WARNING: Secrets provided as command-line arguments are easily exposed. Use of this option should be limited to development and testing. To use an externally managed secret key, use --node-key-file instead.

node_key_type: NodeKeyType

The type of secret key to use for libp2p networking. The secret key of the node is obtained as follows:

• If the --node-key option is given, the value is parsed as a secret key according to the type. See the documentation for --node-key.
• If the --node-key-file option is given, the secret key is read from the specified file. See the documentation for --node-key-file.
• Otherwise, the secret key is read from a file with a predetermined, type-specific name from the chain-specific network config directory inside the base directory specified by --base-dir. If this file does not exist, it is created with a newly generated secret key of the chosen type. The node’s secret key determines the corresponding public key and hence the node’s peer ID in the context of libp2p.

node_key_file: Option<PathBuf>

The file from which to read the node’s secret key to use for libp2p networking. The contents of the file are parsed according to the choice of --node-key-type as follows: ed25519: The file must contain an unencoded 32 byte or hex encoded Ed25519 secret key. If the file does not exist, it is created with a newly generated secret key of the chosen type.
