Password Hashing mainly provides four functions.

/ / check the information about the hash array password_get_info (string $hash) / / create the hash password string password_hash (string $password, integer $algo [, array $options]) / / determine whether the hash password is a specific option, and the boolean password_needs_rehash created by the algorithm (string $hash, integer $algo [, array $options] boolean password_verify (string $password, string $hash) / / verify the password $password = 'password123456';// original password $hash_password = password_hash ($password, PASSWORD_BCRYPT) / encrypt the password if (password_verify ($password, $hash_password) using the BCRYPT algorithm) {echo "password match";} else {echo "password error";}

The password encrypted by password_hash is difficult to crack by using a dictionary, because the password generated each time is different, and the encryption can only be broken by violence. No matter how good the encryption method is, the simple setting of the original password is easy to be cracked, and setting a complex password is the king.
