Creates 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.

$password string Required

Plain text user password to hash.

string The hash string of the password.

This function can be replaced via plugins. If plugins do not redefine these functions, then this will be used instead.

Creates a hash of a plain text password. Unless the global $wp_hasher is set, the default implementation uses PasswordHash, which adds salt to the password and hashes it with 2**8 = 256 passes of MD5. MD5 is used by default because it’s supported on all platforms. You can configure PasswordHash to use Blowfish or extended DES (if available) instead of MD5 with the $portable_hashes constructor argument or property (see examples).
