Manual:

This tool takes a Windows Registry hive file as input, and dumps out all the REG_SZ, REG_EXPAND_SZ, REG_MULTI_SZ and REG_BINARY values.
Default output is a CSV file.
Option --jsonoutput procudes a JSON file that can be consumed by other tools by Didier Stevens, like base64dump.py.

By default, these type of values are dumped: REG_SZ, REG_EXPAND_SZ, REG_MULTI_SZ and REG_BINARY.
This can be changed with option --type.

 s: REG_SZ
 e: REG_EXPAND_SZ
 m: REG_MULTI_SZ
 b: REG_BINARY

For example, option "--type se" will dump all REG_SZ and REG_EXPAND_SZ values.
