Cryptographic Hashing Algorithm

Represents the following attribute in the schema: w:cryptAlgorithmSid

[DocumentFormat.OpenXml.SchemaAttr(23, "cryptAlgorithmSid")]
public DocumentFormat.OpenXml.Int32Value CryptographicAlgorithmSid { get; set; }

public DocumentFormat.OpenXml.Int32Value CryptographicAlgorithmSid { get; set; }

[DocumentFormat.OpenXml.SchemaAttr(23, "cryptAlgorithmSid")]
public DocumentFormat.OpenXml.Int32Value? CryptographicAlgorithmSid { get; set; }

[DocumentFormat.OpenXml.SchemaAttr("w:cryptAlgorithmSid")]
public DocumentFormat.OpenXml.Int32Value? CryptographicAlgorithmSid { get; set; }

public DocumentFormat.OpenXml.Int32Value? CryptographicAlgorithmSid { get; set; }

member this.CryptographicAlgorithmSid : DocumentFormat.OpenXml.Int32Value with get, set

[<DocumentFormat.OpenXml.SchemaAttr(23, "cryptAlgorithmSid")>]

Public Property CryptographicAlgorithmSid As Int32Value

Property Value

Int32Value

Returns Int32Value.

Attributes: SchemaAttrAttribute

Remarks

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

Specifies the specific cryptographic hashing algorithm which shall be used along with the salt attribute and user-supplied password in order to compute a hash value for comparison.

The possible values for this attribute shall be interpreted as follows:

Value	Algorithm
`1`	MD2
`2`	MD4
`3`	MD5
`4`	SHA-1
`5`	MAC
`6`	RIPEMD
`7`	RIPEMD-160
`8`	Undefined. Shall not be used.
`9`	HMAC
`10`	Undefined. Shall not be used.
`11`	Undefined. Shall not be used.
`12`	SHA-256
`13`	SHA-384
`14`	SHA-512
Any other value	Undefined. Shall not be used.

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 cryptAlgorithmSid attribute value of 1 specifies that the SHA-1 hashing algorithm shall be used to generate a hash from the user-defined password.

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