This script automates the extraction of icloud passwords on windows into a passwords.csv file, using Autohotkey to go through the entries, copy them to the clipboard with keyboard shortcuts, and write them to file.

Usage:

1. Download and install icloud from the windows store. Do not open it yet.
2. Once installed, run it as administrator for the first time, until you are signed in. (This fixes a bug where icloud says it is still initialising, every time you try to log in).
3. Close icloud, then run it as a regular user. Open the keychain/passwords section in a new window.
4. Download and install Autohotkey v1
5. Download extract.ahk and run it with autohotkey
6. Focus the icloud password window, at the first item.

I ran some experiments with varying recordsizes, filesizes, and compression. The files were .csv, representative of a simple schema:

full_name,external_id,last_modified
'Past, Gabrielle',40605,'2006-07-09 23:17:20' 
'Vachil, Corry',44277,'1996-09-05 05:12:44'

The files were all generated on an ext4 filesystem. There were three sets of five files, with 75, 100,000, and 1,000,000 rows each, resulting in the following sizes:

❯ find . -name '*small*.csv' -exec du -bc {} + | \

awk 'END {printf "%s %.2f %s\n", "Average file size:", ($1 / (NR-1) / 1024), "KiB"}'
