Password hiding in UNIX

Hi guys,

I use STTY command to make the password invisible.

Now I need to write the password into another file pwd.txt, but in an invisible manner, something like ******. Another thing is to when I echo the content of pwd.txt I get the password I actually typed.

Thanks guys. Help me out.

PASSWORD_VERIFY(3)							 1							PASSWORD_VERIFY(3)

password_verify - Verifies that a password matches a hash

SYNOPSIS
boolean password_verify (string $password, string $hash) DESCRIPTION
Verifies that the given hash matches the given password. Note that password_hash(3) returns the algorithm, cost and salt as part of the returned hash. Therefore, all information that's needed to verify the hash is included in it. This allows the verify function to verify the hash without needing separate storage for the salt or algorithm information. PARAMETERS
o $password - The user's password. o $hash - A hash created by password_hash(3). RETURN VALUES
Returns TRUE if the password and hash match, or FALSE otherwise. EXAMPLES
Example #1 password_verify(3) example <?php // See the password_hash() example to see where this came from. $hash = '$2y$07$BCryptRequires22Chrcte/VlQH0piJtjXl.0t1XkA8pw9dMXTpOq'; if (password_verify('rasmuslerdorf', $hash)) { echo 'Password is valid!'; } else { echo 'Invalid password.'; } ?> The above example will output: Password is valid!

password_hash(3), userland implementation. PHP Documentation Group PASSWORD_VERIFY(3)
