Elliptic curve public keys.

This is a wrapper type for AffinePoint which ensures an inner non-identity point and provides a common place to handle encoding/decoding.

Parsing “SPKI” Keys

X.509 SubjectPublicKeyInfo (SPKI) is a commonly used format for encoding public keys, notably public keys corresponding to PKCS#8 private keys. (especially ones generated by OpenSSL).

Keys in SPKI format are either binary (ASN.1 BER/DER), or PEM encoded (ASCII) and begin with the following:

-----BEGIN PUBLIC KEY-----

To decode an elliptic curve public key from SPKI, enable the pkcs8 feature of this crate (or the pkcs8 feature of a specific RustCrypto elliptic curve crate) and use the [elliptic_curve::pkcs8::FromPublicKey][pkcs8::FromPublicKey] trait to parse it.

When the pem feature of this crate (or a specific RustCrypto elliptic curve crate) is enabled, a [FromStr] impl is also available.

Implementations

Convert an AffinePoint into a PublicKey

Compute a PublicKey from a secret NonZeroScalar value (i.e. a secret key represented as a raw scalar value)

Decode PublicKey (compressed or uncompressed) from the Elliptic-Curve-Point-to-Octet-String encoding described in SEC 1: Elliptic Curve Cryptography (Version 2.0) section 2.3.3 (page 10).

Borrow the inner AffinePoint from this PublicKey.

In ECC, public keys are elliptic curve points.
