struct PublicKeyA P-521 public key used for key agreement.
enum P521An elliptic curve that enables NIST P-521 signatures and key agreement.
enum KeyAgreementA mechanism used to create a shared secret between two users by performing NIST P-521 elliptic curve Diffie Hellman (ECDH) key exchange.
protocol ContiguousBytesIndicates that the conforming type is a contiguous collection of raw bytes whose underlying storage is directly accessible by withUnsafeBytes.
