What are the potential issues with encoding and decoding passwords using a custom PHP class like the one provided in the forum thread?

One potential issue with encoding and decoding passwords using a custom PHP class is the security vulnerability of storing passwords in a reversible format. To solve this issue, it is recommended to store hashed passwords instead of encrypted passwords. Hashing is a one-way function that converts the password into a fixed-length string, making it difficult to reverse engineer the original password. 

// Hashing the password before storing it
$password = 'secret_password';
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Verifying the password
$entered_password = 'secret_password';
if (password_verify($entered_password, $hashed_password)) {
    echo 'Password is correct!';
} else {
    echo 'Password is incorrect!';
}
