因为Laravel5的密码默认加密方式是bcrypt
,希望让YII2也使用这种加密方式,怎么做?Google都难找到资料。

<code> /** * @var string strategy, which should be used to generate password hash. * Available strategies: * - 'password_hash' - use of PHP `password_hash()` function with PASSWORD_DEFAULT algorithm. * This option is recommended, but it requires PHP version >= 5.5.0 * - 'crypt' - use PHP `crypt()` function. * @deprecated Since version 2.0.7, [[generatePasswordHash()]] ignores [[passwordHashStrategy]] and * uses `password_hash()` when available or `crypt()` when not. */</code>
<code> 也就说在2.0.7之后就默认会使用`password_hash`,如果不存在此方法会使用`crypt`</code>
