PasswordHash
From Multi Theft Auto: Wiki
Note: Using passwordHash is the recommended way of storing passwords. |
This function creates a new password hash using a specified hashing algorithm.
Warning: It is strongly recommended to use the async version of the function (i.e. provide a callback function). Otherwise, you will experience short freezes due to the slow nature of the bcrypt 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. Hash length: 60 characters. Note that only the prefix $2y$ is supported (older prefixes can cause security issues).
- options: table with options for the hashing algorithm, as detailed below.
Optional Arguments
- 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!)
- the provided string should be longer or equal than 22 characters
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.
Example
Warning: If you will be using "Example 1" then you will have to save account data "hash_password" after server restart, otherwise this script will no longer work. |
This example makes use of passwordHash and passwordVerify in account creation and account login to boost up security.

Example 1- Use /accountCreate [username] [password] to create an account.
- Use /accountLogin [username] [password] to login in account.
