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.
