Cryptographic Wear-Out for Symmetric Encryption

As we look upon the sunset of a remarkably tiresome year, I thought it would be appropriate to talk about cryptographic wear-out. What is cryptographic wear-out? It’s the threshold when you’ve used the same key to encrypt so much data that you should probably switch to a new key before you encrypt any more. Otherwise, […]

Going Bark: A Furry’s Guide to End-to-End Encryption

Governments are back on their anti-encryption bullshit again. Between the U.S. Senate’s “EARN IT” Act, the E.U.’s slew of anti-encryption proposals, and Australia’s new anti-encryption law, it’s become clear that the authoritarians in office view online privacy as a threat to their existence. Normally, when the governments increase their anti-privacy sabre-rattling, technologists start talking more […]

Comparison of Symmetric Encryption Methods

There seems to be a lot of interest among software developers in the various cryptographic building blocks (block ciphers, hash functions, etc.), and more specifically how they stack up against each other. Today, we’re going to look at how some symmetric encryption methods stack up against each other. If you’re just looking for a short […]
