Struct VerifyingKey 

pub struct VerifyingKey { /* private fields */ }

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.
