A Furry’s Guide to Cryptocurrency

Normally when you see an article that talks about cryptocurrency come across your timeline, you can safely sort it squarely into two camps: For and Against. If you’re like me, you might even make a game out of trying to classify it into one bucket or the other from the first paragraph–sort of like how […]

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, […]

The Subtle Hazards of Real-World Cryptography

Imagine you’re a software developer, and you need to authenticate users based on a username and password. If you’re well-read on the industry standard best practices, you’ll probably elect to use something like bcrypt, scrypt, Argon2id, or PBKDF2. (If you thought to use something else, you’re almost certainly doing it wrong.) Let’s say, due to […]

Commission Prices for Furries and Artists
