# Example configuration file for using the IPython Notebook with a random password

c = get_config()

import os
import base64
from IPython.lib import passwd

password_chars = 8 # number of characters for the generated password

# generate n random bytes
b = os.urandom(password_chars)

# b64 encode, so it's ascii (and truncate, since b64 lengthens a bit)
password = base64.encodestring(b)[:password_chars]

# set the configurable to the hashed/salted value:
c.NotebookApp.password = passwd(password)

# Option 1. cleartext password to the terminal
print
print "Using password: %s" % password
print

# Option 2. write this to a private read-only file

# get the security dir, or put it wherever else you want:
from IPython.config import Application
security_dir = Application.instance().profile_dir.security_dir

# write the file
fname = os.path.join(security_dir, 'notebook_passwd')
with open(fname, 'w') as f:
    f.write(password)

# make it private
import stat
os.chmod(fname, stat.S_IRUSR|stat.S_IWUSR)

# tell the terminal where it went:
print
print "Wrote password to private file: %s" % fname
print
