Struct k256::ecdsa::VerifyingKey[−][src]

pub struct VerifyingKey { /* fields omitted */ }

This is supported on crate features ecdsa-core and ecdsa only.

Expand description

ECDSA/secp256k1 verification key (i.e. public key)

`serde` support

When the serde feature of this crate is enabled, the Serialize and Deserialize traits are impl’d for this type.

The serialization is binary-oriented and supports ASN.1 DER-encoded X.509 Subject Public Key Info (SPKI) as the encoding format.

For a more text-friendly encoding of public keys, use [elliptic_curve::JwkEcKey] instead.
