Hashing algorithms are one-way functions that are used in cryptographic protocols as Pseudo Random Functions (PRF), to assess data integrity or to create a Hash-based Message Authentication Code (HMAC). In many cryptographic constructions, secret data is processed with hashing functions. In these cases, recovering the input given to the hashing algorithm allows retrieving secret data. In this paper, we …
