The scrypt Password-Based Key Derivation Function}

specifies the password-based key derivation function scrypt. The

|
function derives one or more secret keys from a secret string.
|

|
|
It is based on memory-hard functions which offer added protection
|

|
|
against attacks using custom hardware. *)
