The value of encryption
·
I care very deeply about privacy, which translates to a passion for encryption and cryptography. You should care about privacy, too.

Basic cryptography – the Vigenere cipher
·
The Vigenere cipher is more complicated that the Caesar cipher but based on the same idea. It uses a running key to keep your message secure.

Basic cryptography – the Caesar cipher
·
One of the most basic encryption schemes is the Caesar cipher. It’s weak in practice, but a great way to learn how crypto works.

Hashing is not encryption – redux
·
Hashing and encryption are two different things, even if they’re built upon the same cryptographic foundation.
-
Why is it important never to reuse a nonce?
·
A nonce is an important element in cryptography and keep your data secure. But if you ever reuse a nonce, you’ve lost any hope for secrecy.

Hashing is not encryption
·
Encryption, encoding, and hashing are three related but distinct concepts. It’s important for you to understand all three.

Demystifying forms of encryption
·
There are three types of encryption every developer should know: symmetric, asymmetric, and envelope (which is a combination of the previous two).

WordPress Database Encryption
·
How reasonable is the suggestion that WordPress encrypt its database? Really?

Security, Legal Bypass, Warrants, and Apple
·
Apple has announced they won’t be unlocking iOS 8 phones in response to warrants, not as a point of policy, but because the system they’ve built won’t allow it.

I’m a stickler for security, so how can I in good conscience connect to a network I don’t trust?
