SslStream.CipherAlgorithm Property

Gets a value that identifies the bulk encryption algorithm used by this SslStream.

Namespace:  System.Net.Security
Assembly:  System (in System.dll)

Public Overridable ReadOnly Property CipherAlgorithm As CipherAlgorithmType


The CipherAlgorithm property was accessed before the completion of the authentication process or the authentication process failed.

A value of Null is required for the CipherAlgorithm property when the NoEncryption enumeration value is used to construct a SslStream instance.

Windows Server 2003 and Windows XP do not support the Null value. So even if the Null value is used to construct the SslStream instance, the EncryptionPolicy property will be None. The Null value is only returned on Windows Vista and later.

The following code example displays the cryptography settings for the specified stream.

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