SubtleCryptoECDSAP256Keys class

A Keys implementation that uses the SubtleCrypto Web api.

The keys are ECDSA on the P-256 curve (also known as secp256r1) and use SHA-256 as the hash function.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

private_key ↔ CryptoKey

getter/setter pair

public_key ↔ CryptoKey

getter/setter pair

public_key_DER → Uint8List

The DER encoded public-key of these Keys.

final, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

authorize(Uint8List message) → Future<Uint8List>

Signs a message using the private-key of these Keys. Returns a signature on the message.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

new_keys({bool extractable = false}) → Future<SubtleCryptoECDSAP256Keys>

This function generates a new key-pair using the SubtleCrypto generateKey method.

of_the_cryptokeys({required CryptoKey public_key, required CryptoKey private_key}) → Future<SubtleCryptoECDSAP256Keys>

verify({required Uint8List message, required Uint8List signature, required Uint8List public_key_DER}) → Future<bool>

Verifies a signature on a message by an ECDSA P-256 curve key-pair (also known as secp256r1) using SHA-256 as the hash function.
