Code related to AES_KW mode

Functions

source

(format: KeyFormat, key: AesKwCryptoKey): Promise<ArrayBuffer | JsonWebKey>

Export an AES_KW key into the specified format

example
const jwk = await AES_KW.exportKey("jwk", key.self);
example
const jwk = await key.exportKey("jwk");
source

(algorithm?: Omit<EnforcedAesKeyGenParams, "name">, extractable?: boolean, keyUsages?: KeyUsage[]): Promise<AesKwProxiedCryptoKey>

Generate a new AES_KW key

example
const key = await AES_KW.generateKey();
source

(format: KeyFormat, key: BufferSource | JsonWebKey, extractable?: boolean, keyUsages?: KeyUsage[]): Promise<AesKwProxiedCryptoKey>

Import an AES_KW key from the specified format

example
const key = await AES_KW.importKey("jwk", jwk);
source

(format: KeyFormat, wrappedKey: BufferSource, wrappedKeyAlgorithm: EnforcedImportParams, unwrappingKey: AesKwCryptoKey, extractable?: boolean, keyUsages?: KeyUsage[]): Promise<CryptoKey>

Unwrap a wrapped key using the key encryption key

example
const dek = await AES_KW.unwrapKey("raw", wrappedKey, {name: "AES_GCM"}, kek.self);
example
const dek = await kek.unwrapKey("raw", wrappedKey, {name: "AES_GCM"});
source

(format: KeyFormat, key: CryptoKey, wrappingkey: AesKwCryptoKey): Promise<ArrayBuffer>

Wrap another key with an AES_KW key

example
const kek = await AES_KW.generateKey({length: 256}, true, ['wrapKey', 'unwrapKey']);
const dek = await AES_GCM.generateKey();
const wrappedKey = await AES_KW.wrapKey("raw", dek.self, kek.self);
example
const kek = await AES_KW.generateKey({length: 256}, true, ['wrapKey', 'unwrapKey']);
const dek = await AES_GCM.generateKey();
const wrappedKey = await kek.wrapKey("raw", dek.self);
