EcKeyPairData class

P-256 / P-384 / P-521 key pair.

There are many formats for storing elliptic curve key parameters. If you are encoding/decoding JWK (JSON Web Key) format, use package:jwk.

Constructors

EcKeyPairData({required List<int> d, required List<int> x, required List<int> y, required KeyPairType<KeyPairData, PublicKey> type, String? debugLabel})

no setteroverride
publicKey → EcPublicKey
Public key.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
type → KeyPairType<KeyPairData, PublicKey>
Type of the key pair.

Methods

copy() → EcKeyPairData
Copies the private key.
override
destroy() → void
Overwrites sensitive parts of the private key data with zeroes and prevents the private key from being used anymore.
override
extract() → Future<EcKeyPairData>
Reads the private key into memory.
override
extractPublicKey() → Future<EcPublicKey>
Reads the public key.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toDer() → Uint8List
Constructs DER encoding of this public key.
toString() → String
A string representation of this object.
override

Operators

operator ==(Object other) → bool
The equality operator.
override

Static Methods

parseDer(Uint8List der, {required KeyPairType<KeyPairData, PublicKey> type}) → EcKeyPairData
Parses DER-encoded EC public key.
