Balloon hashing is a key derivation function presenting proven memory-hard password-hashing and modern design. It was created by Dan Boneh, Henry Corrigan-Gibbs (both at Stanford University) and Stuart Schechter (Microsoft Research) in 2016. It is a recommended function in NIST password guidelines. The authors claim that Balloon: * has proven memory-hardness properties, * is built from standard primitives: it can use any standards non-space-hard cryptographic hash function as a sub-algorithm (e.g., SHA-3, SHA-512), * is resistant to side-channel attacks: the memory access pattern is independent of the data to be hashed, * is easy to implement and matches the performance of similar algorithms. Balloon is compared by its authors with Argon2, a similarly performing algorithm. (Wikipedia).

Now You Know: Bursting Balloons
When you stick a needle in a balloon, the rubber tears—the balloon pops. But high-speed video reveals the details, and there are some surprises to be had. How does the rubber unzip as it tears? It’s different for a round balloon and a longer balloon-animal balloon. And if the balloon is fi
