Public Property Decryption As String

Property Value

String

A value that indicates the algorithm that is used to encrypt and decrypt forms authentication data. (For information about how to specify the algorithm that is used when view state is encrypted, see the Validation property.) Auto is the default value.

Attributes: TypeConverterAttribute ConfigurationPropertyAttribute StringValidatorAttribute

Exceptions

ConfigurationErrorsException

The selected value is not one of the decryption values.

Remarks

The Decryption property supports the following decryption values:

Auto, which is the default value, specifies that ASP.NET determines which encryption algorithm to use based on configuration default settings.
AES, which specifies that ASP.NET uses the AES algorithm to encrypt data. AES is the default algorithm to encrypt data.
3DES, which specifies that ASP.NET uses the TripleDES algorithm to encrypt data.
A custom algorithm.

This property is typically set declaratively in the decryption attribute of the machineKey element of the Web.config file. For more information, see the machineKey element.
