public Java.Security.IKey Unwrap (byte[] wrappedKey, string wrappedKeyAlgorithm, [Android.Runtime.GeneratedEnum] KeyType wrappedKeyType)

Parameters

wrappedKey
the wrapped key to unwrap.
wrappedKeyAlgorithm
the algorithm for the wrapped key.
wrappedKeyType
the type of the wrapped key (one of: SECRET_KEY , PRIVATE_KEY or PUBLIC_KEY)

Returns
