Enum libp2p::identity::Keypair

source · [−]

pub enum Keypair {
    Ed25519(Keypair),
    Rsa(Keypair),
    Secp256k1(Keypair),
}

Expand description

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)`

An Ed25519 keypair.

`Rsa(Keypair)`

An RSA keypair.

`Secp256k1(Keypair)`

A Secp256k1 keypair.

Implementations

source

impl Keypair

source

pub fn generate_ed25519() -> Keypair

Generate a new Ed25519 keypair.

source

pub fn generate_secp256k1() -> Keypair

Generate a new Secp256k1 keypair.

source

pub fn rsa_from_pkcs8(pkcs8_der: &mut [u8 ]) -> Result<Keypair, DecodingError>

Decode an keypair from a DER-encoded secret key in PKCS#8 PrivateKeyInfo format (i.e. unencrypted) as defined in RFC5208.

source

pub fn secp256k1_from_der(der: &mut [u8 ]) -> Result<Keypair, DecodingError>

Decode a keypair from a DER-encoded Secp256k1 secret key in an ECPrivateKey structure as defined in RFC5915.

source

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

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

source
