Unwrap a previously wrapped key.
[Android.Runtime.Register("engineUnwrap", "([BLjava/lang/String;I)Ljava/security/Key;", "GetEngineUnwrap_arrayBLjava_lang_String_IHandler")]
protected virtual Java.Security.IKey? EngineUnwrap (byte[]? wrappedKey, string? wrappedKeyAlgorithm, int wrappedKeyType);[<Android.Runtime.Register("engineUnwrap", "([BLjava/lang/String;I)Ljava/security/Key;", "GetEngineUnwrap_arrayBLjava_lang_String_IHandler")>]
abstract member EngineUnwrap : byte[] * string * int -> Java.Security.IKey
override this.EngineUnwrap : byte[] * string * int -> Java.Security.IKeyParameters
- wrappedKey
- Byte[]
the key to be unwrapped.
- wrappedKeyAlgorithm
- String
the algorithm associated with the wrapped key.
- wrappedKeyType
- Int32
the type of the wrapped key. This is one of
SECRET_KEY, PRIVATE_KEY, or
PUBLIC_KEY.
Returns
the unwrapped key.
- Attributes
Exceptions
if the wrappedKey cannot be unwrapped to a key of
type wrappedKeyType for the wrappedKeyAlgorithm.
if no provider can be found that can create a key of type
wrappedKeyType for the wrappedKeyAlgorithm.
Remarks
Unwrap a previously wrapped 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 unwrap a previously wrapped key. Such an override is expected to throw an InvalidKeyException if the given wrapped key cannot be unwrapped. If this method is not overridden, it always throws an UnsupportedOperationException.
