[<Android.Runtime.Register("engineWrap", "(Ljava/security/Key;)[B", "GetEngineWrap_Ljava_security_Key_Handler")>]
abstract member EngineWrap : Java.Security.IKey -> byte[]
override this.EngineWrap : Java.Security.IKey -> byte[]

Parameters

key
IKey

the key to be wrapped.

Returns

Byte[]

Exceptions

if the size of the resulting bytes is not a multiple of the cipher block size.

if this cipher instance cannot wrap this key.

Remarks

Wrap a key.

This concrete method has been added to this previously-defined abstract class. (For backwards compatibility, it cannot be abstract.) It may be overridden by a provider to wrap a key. Such an override is expected to throw an IllegalBlockSizeException or InvalidKeyException (under the specified circumstances), if the given key cannot be wrapped. If this method is not overridden, it always throws an UnsupportedOperationException.
