obfuscation.format

The file format is essentially  a CSV file that has the following fields

<App label>, <model Name>, <field_name>, <Obfuscation Type>

The first three fields are fairly obvious.  The obfuscation types supported are

name         : Tells the obfuscator that this is a name field.  Obfuscator will use a random name from its internal name database to populate this field.  Typically use this for first_name and last_name fields
zero         : Tells the obfuscator to fill with zeros
none         : Tells the obfuscator to set the field to None
randomstring : Tells the obfuscator to put a random string in the field
randomnumber :  Tells the obfuscator to put a random number in the field
