The big guys don’t always know what they’re doing

You’d think that a really big software company, like Adobe, would know what it’s doing But no. You may have noticed that there was a big data breach: millions of usernames and (encrypted) passwords were stolen. But they were encrypted, so no big deal, right?

Ah. Well. That’s the point. As this article explains, it was indeed the encrypted passwords that were stolen, not the hashes (if this is gobbledygook to you, the article has a very clear explanation of what this means). As the password hints were stolen too, it turns out to be really easy to decrypt many of them.

Now, I am by no means a security expert. And for websites I build nowadays, I use a ready-rolled solution (usually WordPress). But when I wrote things from scratch, even I knew better than to store the encrypted passwords. I may not have used the most secure hacking algorithm, or proper salting, but I didn’t encrypt the passwords.
