# This is a reference script to add checksums to downloadable #
# subscriptions. The checksum will be validated by Adblock Plus on download #
# and checksum mismatches (broken downloads) will be rejected. #
# #
# To add a checksum to a subscription file, run the script like this: #
# #
# python addChecksum.py < subscription.txt > subscriptionSigned.txt #
# #
# Note: your subscription file should be saved in UTF-8 encoding, otherwise #
# the operation will fail. #
