wp_hash_password() WP 1.0

Create a hash (encrypt) of a plain text password.

For integration with other applications, this function can be overwritten to instead use the other package password checking algorithm.

Notes:

  • Global. PasswordHash. $wp_hasher PHPass object

This is a pluggable function, and it can be replaced from plugin. It means that this function is defined (works) only after all plugins are connected (included), but before this moment the function has not yet been defined... Therefore, you cannot call this and all functions depended on this function directly from a plugin code. It must be called via hook plugins_loaded or later, for example on hook init.

Function replacement (override) — in a plugin you can create a function with the same name, then it will replace this function.

Is the basis for: wp_set_password()

No Hooks.

Return

String. The hash string of the password

Usage

wp_hash_password( $password );
$password(string) (required)
Plain text user password to hash

Code of wp_hash_password: wp-includes/pluggable.php VER 4.9.8

<?php
function wp_hash_password($password) {
	global $wp_hasher;

	if ( empty($wp_hasher) ) {
		require_once( ABSPATH . WPINC . '/class-phpass.php');
		// By default, use the portable hash from phpass
		$wp_hasher = new PasswordHash(8, true);
	}

	return $wp_hasher->HashPassword( trim( $password ) );
}
