示例1: getCryptedPassword
/**
* Formats a password using the current encryption.
*
* @param string $plaintext The plaintext password to encrypt.
* @param string $salt The salt to use to encrypt the password. []
* If not present, a new salt will be
* generated.
* @param string $encryption The kind of password encryption to use.
* Defaults to md5-hex.
* @param boolean $show_encrypt Some password systems prepend the kind of
* encryption to the crypted password ({SHA},
* etc). Defaults to false.
*
* @return string The encrypted password.
*
* @since 11.1
*
* @deprecated 4.0
