Struct gbl::P256KeyPair

pub struct P256KeyPair { /* fields omitted */ }

An elliptic curve key pair (on P-256 / secp256r1 / prime256v1).

This struct contains the private key and the corresponding public key.

Methods

impl P256KeyPair

pub fn from_der<D: AsRef<[u8]>>(der: D) -> Result<Self, Error>

Decodes a P-256 key pair from a DER-encoded ECPrivateKey structure.

The ECPrivateKey ASN.1 structure is specified in RFC 5915.

Examples

let der = [

let keypair = P256KeyPair::from_der(&der[..])?;

pub fn from_pem<P: AsRef<str>>(pem: P) -> Result<Self, Error>

Decodes a P-256 key pair from a PEM-encoded ECPrivateKey structure.

The ECPrivateKey ASN.1 structure is specified in RFC 5915.

let pem = r#"

let keypair = P256KeyPair::from_pem(pem)?;

pub fn to_public(&self) -> P256PublicKey

Returns the public component of this key pair.
