The first thing is to make a comparison of functions of SHA and opt for the safest algorithm that supports your programming language (PHP).

Then you can chew the official documentation to implement the hash() function that receives as argument the hashing algorithm you have chosen and the raw password.

sha256 => 64 bits sha384 => 96 bits sha512 => 128 bits

The more secure the hashing algorithm is, the higher the cost in terms of hashing and time to recover the original value from the server side.

$hashedPassword = hash('sha256', $password);
