openpyxl.utils.protection.hash_password(plaintext_password='')

Create a password hash from a given string for protecting a worksheet only. This will not work for encrypting a workbook.

This method is based on the algorithm provided by Daniel Rentz of OpenOffice and the PEAR package Spreadsheet_Excel_Writer by Xavier Noguer <xnoguer@rezebra.com>. See also http://blogs.msdn.com/b/ericwhite/archive/2008/02/23/the-legacy-hashing-algorithm-in-open-xml.aspx
