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.[1][2] It is a recommended function in NIST password guidelines.[3]

The authors claim that Balloon:

Balloon is compared by its authors with Argon2, a similarly performing algorithm.[1]

Algorithm[edit]

There are three steps in the algorithm:[1]

  1. Expansion, where an initial buffer is filled with a pseudorandom byte sequence derived from the password and salt repeatedly hashed.
  2. Mixing, where the bytes in the buffer are mixed time_cost number of times.
  3. Output, where a portion of the buffer is taken as the hashing result.
