Public Overridable Function CreateKeyWrapProviderForUnwrap (key As SecurityKey, algorithm As String) As KeyWrapProvider

Parameters

key: SecurityKey

The SecurityKey to use.

algorithm: String

The algorithm to use.

Returns

KeyWrapProvider

An instance of KeyWrapProvider.

Exceptions

ArgumentNullException

Thrown if algorithm is null or empty.

ArgumentException

Thrown if the combination of key and algorithm is not supported.

InvalidOperationException

Thrown if the type returned by Create(String, Object[]) is not assignable to KeyWrapProvider.
