Enum libp2p_core::identity::Keypair

pub enum Keypair {
    Ed25519(Keypair),
}

Identity keypair of a node.

Example: Generating RSA keys with OpenSSL

openssl genrsa -out private.pem 2048
openssl pkcs8 -in private.pem -inform PEM -topk8 -out private.pk8 -outform DER -nocrypt
rm private.pem      # optional

Loading the keys:

let mut bytes = std::fs::read("private.pk8").unwrap();
let keypair = Keypair::rsa_from_pkcs8(&mut bytes);

Variants

Ed25519(Keypair)

👎Deprecated since 0.1.0: This enum will be made opaque in the future, use Keypair::try_into_ed25519 instead.

An Ed25519 keypair.

Implementations

impl Keypair

pub fn generate_ed25519() -> Keypair

Generate a new Ed25519 keypair.

pub fn into_ed25519(self) -> Option<Keypair>

👎Deprecated: This method name does not follow Rust naming conventions, use Keypair::try_into_ed25519 instead.

pub fn try_into_ed25519(self) -> Result<Keypair, OtherVariantError>

pub fn ed25519_from_bytes( bytes: impl AsMut<[u8]>, ) -> Result<Keypair, DecodingError>

pub fn sign(&self, msg: &[u8]) -> Result<Vec<u8>, SigningError>

Sign a message using the private key of this keypair, producing a signature that can be verified using the corresponding public key.

pub fn public(&self) -> PublicKey

Get the public key of this keypair.

pub fn to_protobuf_encoding(&self) -> Result<Vec<u8>, DecodingError>

Encode a private key as protobuf structure.

pub fn from_protobuf_encoding(bytes: &[u8]) -> Result<Keypair, DecodingError>

Decode a private key from a protobuf structure and parse it as a Keypair.
