How to encrypt a password that is inserted into a MySQL table? [duplicate]

Answer 1

Sanitize your input data first. $password = filter_input(INPUT_POST, 'password', FILTER_SANITIZE_STRING);

Hash your password string

$hashedPassword = hash('sha512', $password);

A better way to hash the password would be to use the new password hash API

$hashedPassword = password_hash($password, PASSWORD_DEFAULT);
