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

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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
public abstract ICryptoTransform CreateDecryptor(
    byte[] rgbKey,
    byte[] rgbIV


  • rgbKey
    Type: array<System.Byte[]
    The secret key to use for the symmetric algorithm.
  • rgbIV
    Type: array<System.Byte[]
    The initialization vector to use for the symmetric algorithm.

Return Value

Type: System.Security.Cryptography.ICryptoTransform
A symmetric decryptor object.


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