Foser Posted May 31, 2007 Share Posted May 31, 2007 I'm looking for a slight tutorial about how to encrypt a password in mysql and decrypt it so when you want to login it's simple. Also I'd like to find a simple tutorial on how to make a basic login with sessions to few 3-4 pages. thanks Link to comment https://forums.phpfreaks.com/topic/53712-mysql-password-encryption-and-decryption/ Share on other sites More sharing options...
chocopi Posted May 31, 2007 Share Posted May 31, 2007 Well the best way to encrypt a password is through md5 and sessions are quite tricky to get used to so I would look at: Sessions So with the md5 you would want your password to be something like this: <?php $password = $_POST['password']; $password = md5($password); ?> <html> <body> <form name="password" action="<?PHP_SELF?>" method="post"> <input type="password" name="password" value="$password"> <input type="submit" name="submit" value="Submit"> </form> </body> </html> <?php // Insert assuming you already connected to the database $query = "INSERT INTO tablename (fieldname) VALUES('$password')"; mysql_query($query) or die(mysql_error()); ?> And then for the login have: <?php $username = $_POST['username']; $password = $_POST['password']; $password = md5($password); // Check if combo is in database $query = mysql_query("SELECT fieldname FROM tablename WHERE fieldname='$username' && fieldname='$password'"); $result = mysql_num_rows($query); if($result > 0){ echo ("Congrats"); } else { echo ("Invalid"); } ?> <html> <body> <form name="login" action="<?PHP_SELF?>" method="post"> <input type="username" name="username" value="$username"> <input type="password" name="password" value="$password"> <input type="submit" name="submit" value="Submit"> </form> </body> </html> This code is completly untested and probably has some faults, but try it and report back Hope it helps ~ Chocopi Link to comment https://forums.phpfreaks.com/topic/53712-mysql-password-encryption-and-decryption/#findComment-265464 Share on other sites More sharing options...
Daniel0 Posted May 31, 2007 Share Posted May 31, 2007 I'm looking for a slight tutorial about how to encrypt a password in mysql and decrypt it so when you want to login it's simple. There is no need to decrypt again. Use a one-way hashing algorithm such as SHA-1 or MD5. Then when the user enter their password to login again they you would just encrypt the entered password and compare it with the already encrypted password stored in the database.
