How can one ensure the security of passwords when transferring them between different systems in PHP?

When transferring passwords between different systems in PHP, it is essential to ensure the security of the passwords by encrypting them before transmission. One way to achieve this is by using a strong encryption algorithm like bcrypt to hash the passwords before sending them. This way, even if the data is intercepted during transmission, the passwords will remain secure. 

// Encrypt the password using bcrypt before transferring it
$password = "mySecurePassword";
$hashedPassword = password_hash($password, PASSWORD_DEFAULT);

// Transmit $hashedPassword to the other system securely
