SymmetricAlgorithm.CreateEncryptor Method

Creates a symmetric encryptor object with the current Key property and initialization vector (IV).

Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)
abstract CreateEncryptor : unit -> ICryptoTransform  
override CreateEncryptor : unit -> ICryptoTransform

Return Value

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

If the current Key property is a null reference (Nothing in Visual Basic), the GenerateKey method is called to create a new random Key. If the current IV property is a null reference (Nothing in Visual Basic), the GenerateIV method is called to create a new random IV.

Use the CreateDecryptor overload with the same signature to decrypt the result of this method.

The following example encrypts a string using the transform object returned from the CreateEncryptor method.
