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

Creates a symmetric Rijndael decryptor object with the specified Key and initialization vector (IV).

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

abstract CreateDecryptor : 
        rgbKey:byte[] * 
        rgbIV:byte[] -> ICryptoTransform  
override CreateDecryptor : 
        rgbKey:byte[] * 
        rgbIV:byte[] -> ICryptoTransform

Parameters

rgbKey
Type: System.Byte[]

The secret key to be used for the symmetric algorithm. The key size must be 128, 192, or 256 bits.

rgbIV
Type: System.Byte[]

The IV to be used for the symmetric algorithm.

Return Value

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

ExceptionCondition
ArgumentNullException

The rgbKey parameter is a null reference (Nothing in Visual Basic).

-or-

The rgbIV parameter is a null reference (Nothing in Visual Basic).

CryptographicException

The value of the Mode property is not ECB, CBC, or CFB.

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

The rgbkey size must be 128, 192, or 256 bits.

The following code example demonstrates how to use the CreateDecryptor method to decrypt messages encoded with the same signature parameter.

No code example is currently available or this language may not be supported.
