Choosing a Secure Password

The best way to explain how to choose a good password is to explain how they're broken. The general attack model is what’s known as an offline password-guessing attack. In this scenario, the attacker gets a file of encrypted passwords from somewhere people want to authenticate to. His goal is to turn that encrypted file into unencrypted passwords he can use to authenticate himself. He does this by guessing passwords, and then seeing if they’re correct. He can try guesses as fast as his computer will process them – and he can parallelize the attack – and gets immediate confirmation if he guesses correctly. Yes, there are ways to foil this attack, and that's why we can still have four-digit PINs on ATM cards, but it's the correct model for breaking passwords.

"I must say that I find television very educational.
The minute somebody turns it on,
I go to the library and read a book."

Consider a Gift to the Annual Appeal

It's clear, you love your libraries! We hope you'll consider making a generous contribution to APL's Annual Appeal.

The Albany Public Library changes lives, answering life's most complex questions and serving as the public's destination for social, intellectual and cultural discourse.

As our world changes, Albany's libraries face new challenges with increased demand for more books, materials, and programs housed in aging and outdated facilities. That's why your annual contribution is so important.

Your gifts to the library though The Albany Public Library Foundation means the difference between adequate libraries and great libraries. With private support, we can expand our collections and services to include more of what customers want in materials, technology, and programs.

So, look for the Annual Appeal information in the mail. We thank you.
