hashing passwords

[patchido]

I am trying to upload a big amount of users into a table in mysql, for this i want to import via phpmyadmin, the only problem is that the password is hasshed, so i did a php file for converting the bulk of passwords into sha1, i did a test with one of them and it is not the same value as if i created with another, can anyone tell why??

 

 

this is my code for the bulk.

 

 

<?php


if (isset($_POST['submit'])) { 
	
	
	
	$textarea = $_POST['passwords'];
	$pass_array = explode("\n",$textarea);
	$sha1_array= array();
	foreach($pass_array as $pass){
	
	$sha1_array[] = sha1($pass);
		
	}
	
	echo print_r($sha1_array);	
		
}
 


	

?>


<form action="pass.php" method="post">
<textarea name="passwords" cols="20" rows="1100"></textarea><br />
<input type="submit" name="submit" value="sha1" />
</form>

 

 

 

 

Thanks

i figured out that this is caused on the \n after each line, how can i get rid of this?

FYI: You can greatly reduce that code (and implement trim):

$sha1_array = array_map('sha1', array_map('trim', explode("\n", $_POST['passwords'])));
echo print_r($sha1_array);
