extractable
The read-only extractable property of the CryptoKey interface
indicates whether or not the key may be extracted using
SubtleCrypto.exportKey()
or
SubtleCrypto.wrapKey().
If the key cannot be exported,
exportKey()
or
wrapKey()
will throw an exception if used to extract it.
Implementation
external bool get extractable;
