import CryptoA cryptography library for Swift.
struct PrivateKeyA P-256 private key used for key agreement.
enum P256An elliptic curve that enables NIST P-256 signatures and key agreement.
enum KeyAgreementA mechanism used to create a shared secret between two users by performing NIST P-256 elliptic curve Diffie Hellman (ECDH) key exchange.
struct PublicKeyA P-256 public key used for key agreement.
struct SharedSecretA key agreement result from which you can derive a symmetric cryptographic key.
init() Creates a NIST P-256 elliptic curve private key for use with Diffie-Hellman key exchange.
init(compactRepresentable: Bool = true) Creates a random P-256 private key for key agreement.
init<Bytes>(derRepresentation: Bytes) throws where Bytes : RandomAccessCollection, Bytes.Element == UInt8 Creates a P-256 private key for key agreement from a Distinguished Encoding Rules (DER) encoded representation.
