GeneralCryptoHelper class abstract interface

General cryptographic helper interface for key validation and algorithm handling.

Combines common crypto utilities (key matching, algorithm detection) and provides static methods for verifying key pairs (symmetric/asymmetric).

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

getKeyAlgorithm(Map key, [String? defaultValue]) → String?

Extracts the algorithm name from a key's metadata map.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Static Properties

PROMISE → Uint8List

sample data for checking keys

final

Static Methods

matchAsymmetricKeys(SignKey sKey, VerifyKey pKey) → bool

Verifies that an asymmetric key pair (sign/verify) are a matching pair.

matchSymmetricKeys(EncryptKey encKey, DecryptKey decKey) → bool

Verifies that symmetric keys (encrypt/decrypt) are a matching pair.
