Answer 1

Unpacked Chrome extensions ID is generated based on the path of it's directory. For unpacked extension you can generate the id in following way (code in Python):

import hashlib

m = hashlib.sha256()
m.update(bytes(PATH.encode('utf-8')))
EXTID = ''.join([chr(int(i, base=16) + ord('a')) for i in m.hexdigest()][:32])

where PATH is normalized path to the extension, ie.:

PATH = os.path.dirname(os.path.realpath(__file__))
