Struct gbl::P256PublicKey

pub struct P256PublicKey { /* fields omitted */ }

A public P-256 key (aka secp256r1 / prime256v1).

Methods

impl P256PublicKey

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

Decodes a P-256 public key from a DER-encoded SubjectPublicKeyInfo structure.

The SubjectPublicKeyInfo structure is described in RFC 5280.

Examples

let der = [
    0x30, 0x59, 0x30, 0x13, 0x06, 0x07, 0x2a, 0x86, 0x48, 0xce, 0x3d, 0x02,
    0x01, 0x06, 0x08, 0x2a, 0x86, 0x48, 0xce, 0x3d, 0x03, 0x01, 0x07, 0x03,
    0x42, 0x00, 0x04, 0xdc, 0xc7, 0xaf, 0xdd, 0x92, 0xe7, 0xc2, 0x0b, 0xfe,
    0xbb, 0xd7, 0x08, 0x45, 0xb3, 0x4e, 0x92, 0xea, 0x2d, 0x52, 0xc3, 0x38,
    0xaa, 0x9b, 0x68, 0xe8, 0x2b, 0x6c, 0x82, 0x37, 0x77, 0x29, 0x8f, 0x23,
    0x69, 0x39, 0xef, 0x32, 0x72, 0x4c, 0x43, 0x44, 0xc8, 0x5f, 0x06, 0x6a,
    0x6f, 0x37, 0xb1, 0x3e, 0x35, 0x8f, 0x8a, 0xe5, 0x99, 0x61, 0x99, 0x3d,
    0x1e, 0x63, 0x6d, 0x68, 0x5c, 0xc1, 0xe2
];
let pubkey = P256PublicKey::from_der(&der[..])?;

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

Decodes a P-256 public key from a PEM-encoded SubjectPublicKeyInfo structure.

The PEM data should have a header of -----BEGIN PUBLIC KEY-----.

The SubjectPublicKeyInfo structure is described in RFC 5280.

Examples

let pem = r#"
-----BEGIN PUBLIC KEY-----
