WriteProtection.CryptographicAlgorithmClass Property

Definition

Namespace:

DocumentFormat.OpenXml.Wordprocessing

Assembly:

DocumentFormat.OpenXml.dll

Package:

DocumentFormat.OpenXml v3.0.1

Cryptographic Algorithm Class

Represents the following attribute in the schema: w:cryptAlgorithmClass

C#

public DocumentFormat.OpenXml.EnumValue<DocumentFormat.OpenXml.Wordprocessing.CryptAlgorithmClassValues>? CryptographicAlgorithmClass { get; set; }

Property Value

EnumValue<CryptAlgorithmClassValues>

Returns EnumValue<T>.

Remarks

The following information from the ECMA International Standard ECMA-376 can be useful when working with this class.

Specifies the class of cryptographic algorithm used by this protection. The initial version of the Office Open XML Standard only supports a single version - hash - but future versions may expand this as necessary.

Consider a WordprocessingML document with the following information stored in one of its protection elements:

<w:… w:cryptAlgorithmClass="hash"   
  w:cryptAlgorithmType="typeAny"   
  w:cryptAlgorithmSid="1"  
  w:hash="9oN7nWkCAyEZib1RomSJTjmPpCY=" />  

The cryptAlgorithmClass attribute value of hash specifies that the algorithm used for the password is a hashing algorithm.

The possible values for this attribute are defined by the ST_AlgClass simple type.
