[DataContractAttribute]
public enum HashingType

Members

Member name	Value	Description
None	0	No document hashing.
BinaryHashOnly	1	Calculate only MD5/SHA-1 binary hashes using document's file bytes. If this enum value is selected then properties MD5BinaryHash and SHA1BinaryHash get populated with document's binary hash during content extraction.
BinaryAndContentHash	2	Calculate MD5/SHA-1 binary hashes using document's file bytes and also calculate proprietary MD5/SHA-1 'content hash' on content hash supported file formats. If this enum value is selected then properties MD5BinaryHash and SHA1BinaryHash get populated with the document's binary hash during content extraction. In addition, and if content hash is supported for the file format, the document's MD5ContentHash and SHA1ContentHash are calculated and populated during content extraction. NOTE: Email formats always have their content hash calculated as long as HashingType value is not set to None. This property value only enables content hashing for supported spreadsheet, word processing, and presentation file formats.
