<ST_AlgClass> (Cryptographic Algorithm Classes)
This simple type specifies the possible classes of cryptographic algorithm used by protection. 
Note: : The initial version of this Office Open XML Standard only supports a single version - 
hash - but future versions may expand this as necessary. example: 
<p:… p:cryptAlgorithmClass="hash" p:cryptAlgorithmType="typeAny" p:cryptAlgorithmSid="1" p:hashData="9oN7nWkCAyEZib1RomSJTjmPpCY=" />
The @cryptAlgorithmClass attribute value of hash specifies that the algorithm used for the password is a hashing algorithm. ]
This simple type's contents are a restriction of the XML Schema string datatype.
The following are possible enumeration values for this type:
