Answer 1

You can encrypt the password using the following:

define('SALT', 'atopsecretphrase'); 

function encrypt($text) 
{ 
    return trim(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, SALT, $text, MCRYPT_MODE_ECB, mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND)))); 
} 

function decrypt($text) 
{ 
    return trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, SALT, base64_decode($text), MCRYPT_MODE_ECB, mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND))); 
} 

$encryptedmessage = encrypt("mypassword"); 
echo decrypt($encryptedmessage); 

Answer 2

You can hash your password with md5() or sha1()

Answer 3

If you need to pass the password on the best you can do is encrypt the password.

If you only need to check the password you should look at hashing. See: http://phpsec.org/articles/2005/password-hashing.html

Answer 4

You could save it hashed. For example, sha1($password) will already return the same hash for the same password, but it cannot be decrypted.

That way the password is safe, and you could always take the input of the user, hash it the same way and compare his password entered with the one in the XML file.

Otherwise, another solution is the write your own encryption/decryption algorithm instead of hashing.

Answer 5

Try the following:

echo md5("password");

Will return:
