Hi Mark,

maybe i was not clear enough.

I want to create and encrypt passwords with rev, which then can be used for http authentication on a webserver.

I want my rev app to create a folder on the webserver, create passwords,encrypt them, create the .httaccess and the .htpassword file and upload them to the newly created folder. 

My rev app is already doing so, with one exception: I am using a php file on the webserver to encrypt  the passwords. I am using the following code to get the encrypted password into rev.

put URL ("http://...../passwdcreate.php?pass=" & sPassword) into sOutput
if line 1 of sOutput is "Password created" 
then 
put line 2 of sOutput into sEncryptedPassword
and so on


My PHP code is like this

<?php
// Passwort setzen
echo "Password created";
echo"<br>"	;
echo crypt($pass , 'sa');
?> 


Regards,

Matthias
