This template is no longer in use as it results in poor readability. This function creates a new password hash using a specified hashing algorithm.

Syntax

string passwordHash ( string password, string algorithm [, table options = {} ][, function callback ])

Required Arguments

  • password: The password to hash.
  • algorithm: The algorithm to use:
    • bcrypt: use the bcrypt hashing algorithm

Optional Arguments

  • options: table with options for the hashing algorithm, as detailed below
  • callback: providing a callback will run this function asynchronously, the arguments to the callback are the same as the returned values below.

Options for each hashing algorithm

  • bcrypt:
    • cost (int), default: 10. Visit this link to determine the number of rounds appropriate for your server.
    • salt (string), default: automatically generate salt
      • an empty string will automatically generate a salt with the cost provided
      • if a string is provided, the given salt is used (do not do this!)

Returns

Returns the hash as a string if hashing was successful, false otherwise. If a callback was provided, the aforementioned values are arguments to the callback, and this function will always return true.
