Hello software developers,

Please check your code to ensure you're not making one of the following mistakes related to cryptography.

I. General Mistakes

Writing your own home-grown cryptography primitives (For example: Mifare Classic)
- Exception: For the sake of learning, but don't deploy it in production.
Using a fast hash function (e.g. MD5, SHA256) for storing passwords. Use bcrypt instead.
Not using a cryptographically secure random number generator

duplicates = multiple editions

	$ echo ${FILE%.*} # remove ext

	# Himawari-8 Downloader

	# This script will scrape the latest image from the Himawari-8 satellite, recombining the tiled image,
	# converting it to a JPG which is saved in My Pictures\Himawari\ and then set as the desktop background.
