SymmetricAlgorithm.CreateDecryptor Method (Byte[], Byte[])

When overridden in a derived class, creates a symmetric decryptor object with the specified Key property and initialization vector (IV).

Namespace: System.Security.Cryptography
Assembly: mscorlib (in mscorlib.dll)

Public MustOverride Function CreateDecryptor ( _
	rgbKey As Byte(), _
	rgbIV As Byte() _
) As ICryptoTransform
Dim instance As SymmetricAlgorithm
Dim rgbKey As Byte()
Dim rgbIV As Byte()
Dim returnValue As ICryptoTransform

) : ICryptoTransform



The secret key to use for the symmetric algorithm.


The initialization vector to use for the symmetric algorithm.

Return Value

A symmetric decryptor object.

This method decrypts an encrypted message created using the CreateEncryptor overload with the same parameters.
