On multiple hashing
Hash functions are cryptographic functions that calculate a fixed-size, unique hash for a given string. Their role in computer science is significant: we use them to calculate control sums, in cryptographic protocols and to store users’ passwords. In this post I’d like to focus on the last usage, and to be more precise: focus on the idea of multiple password hashing. If you have ever thought why not improve their security in this way, you are welcome to read it.
