The SHA256 hash with salt is generated by concatenating the salt to the password and then hashing the resulting string. The salt is then appended to the generated hash to form the complete hash. This complete hash is then stored in the database. When a user attempts to login, the salt i...

Boomerang attackSummary: SHA-2 (SHA-224, SHA-256, SHA-384 and SHA-512) is hash function family issued by the National Institute of Standards and Technology (NIST) in 2002 and is widely used all over the world. In this work, we analyze the security of SHA-512 with respect to boomerang...
In this paper, we try to evaluate the security margins of three hash functions namely SHA-512, SHA-256 and DHA-256 against the boomerang attack.Firstly, we give a boomerang attack on 48-step SHA-512 with a practical complexity of 2~(51). The correctness of this attack is verified by ...
