Slow key-derivation functions like SCrypt, BCrypt or PBKDF2 are necessary, to protect relatively short and weak passwords, or to generate a key from such passwords (Password-Based-Key-Derivation-Function). Users need to remember their passwords, so they are typically not very strong, that's why SCrypt was choosen to hash the user password. On the other ...


scrypt needs much more power than SHA2 as it needs computing power and memory. The master key is protected using scrypt because it is much slower. But the passwords for the websites are hashed using the strong scrypt key but this time SHA256 is used because it is faster. The scrypt key is used for the hash and builds a strong base for the hash. Hashing the ...
