No Comments on Asymmetric Cryptographic Commitments

Recently, it occurred to me that there wasn’t a good, focused resource that covers commitments in the context of asymmetric cryptography. I had covered confused deputy attacks in my very short (don’t look at the scroll bar) blog post on database cryptography., and that’s definitely relevant. I had also touched on the subject of commitment […]

10 Comments on 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 […]
