The Phisical and The Result

this link is for have the physically layer from power designer...after you make the conceptual, you can generate to be a physically layer....the example process to make physically layer can you download here
and after that you can make the physically layer to be a SQL script...you can download here to know about the generate process...

the Conceptual

this afternoon my student question about conceptual data diagram in power designer....some of them feel it's very difficult...so I make example how to make it easily...woth this video I make presentation today,,,this is my first practical video study in this university....and now i share to the world....oke lets enjoy it...:)  download

share your problem with KORAN Software

This a system that My Close Friend Joedith and me, make a system. How to search Koran verses to our problem. Using text mining and correlation method, we try to make it although have a lot of problem…but, in the end, we success to make trial version (Indonesian Verses) …to download Java Project click here…and this is to download the database click here

There are some example to  help yo to used it

have nice try..and please share to me about the problem..so we can make the better system

Random di PHP

A friend asked about the random function in PHP. coincidence this blog has not been updated. it altogether, update blogs and helped my friends. ok..let's play the listing ...:) :

echo rand() . "\n";
echo rand() . "\n";

echo rand(5, 15);
?>

result :
123
242
2

random in the query

// First get the last id from the table

$SQL = "SELECT * FROM HIGHLIGHTS ORDER BY highlight_id DESC LIMIT 1";
$result = mysql_query( $SQL );
while( $row = mysql_fetch_array( $result ) ) {
$ending_id = $row["highlight_id"];
}

// I only want the 5 most recent entries
// So I just subtract 5 from the last ID

$starting_id = $ending_id - 5;

// Because I we don't want a nagitive number I just
// make sure that the starting ID is at least 1

if($starting_id <= 0){
$starting_id = "1";
}

// now I run the the $starting_id $ending_id at RAND

$howey = rand($starting_id, $ending_id);

// Now I use howey as my id

$SQL = "SELECT * FROM HIGHLIGHTS WHERE highlight_id = '$howey'";
$result = mysql_query( $SQL );
while( $row = mysql_fetch_array( $result ) ) {
$highlight_id = $row["highlight_id"];
$highlight_title = $row["highlight_title"];
}
echo "$highlight_id $highlight_title";
?>

Mail Client With ElGamal Cryptography

System architecture of the program Mail Client with ElGamal cryptography is :





From the picture above can be seen that the mail client sender encrypts the message by sending a plain text parameter of the encryption function. After that sends cipher text encryption function as a result of encryption. With the SMTP port and the cipher text of the message sent to the Mail Server. Mail Server Mail Server sends to the destination if the recipient has a different Mail Server. With POP3 or Imap protocol then the message recipient mail client can receive email. Email recipients can decrypt the cipher text sent parameters. Decryption function will check first private key. After the enter key then the private decryption function can send plain text decryption results. The essence of the above programs are Mail client can send an email to the mail server after encryption. And the recipient mail client can download email delivery at Mail Server, and then decrypt.

the process is :

1. 1) The process triggers the generation of these numbers is a process to generate random prime numbers as a trigger for ElGamal key lock so that adds to the complexity in its calculations. The more complicated the calculation will be more secure algorithm.
2. 2) Power private key (x) is the process to calculate the number x of keywords (in a phrase or sentence) that users input. With this process the X does not come out of the range specified in ElGamal.
3. 3) Generation of public key (y) this process is to calculate the public key (y) by using the private key (x). Y goal is the key to be distributed to the public, so that others can encrypted messages to be sent to us. And we can decrypt the message with the key x (private).
4. 4) Encrypt the message that the process used to encrypt the plain text or email message early. ElGamal method then this process will produce cipher text (password) with 2 characters represent the plain text characters 1. So the cipher text twice the amount of plain text.
5. 5) Send the message this process is the process of sending a message to the Java mail to Email Server. This process uses the SMTP protocol to send email. Messages sent in the form of byte [] so that the sending process can go smoothly and be accepted by the Mail Server.
6. 6) Reading emails this process is the process for reading emails sent. Initially Email Client to download messages to the Mail Server using the POP3 or Imap protocol. Users can choose one of these 2 protocols. After downloading the message is displayed in the table in java mail messages.
7. 7) Decryption email messages in your email Server is not in decryption. Always in a cipher text. So to read email decryption process carried out beforehand. This process checks first private key. Then decryption process can be done with the same result as the plain text before encryption by the sender in the email.

Create Mail Client

in this post, mail client created using Java mail library. Java mail is a special library for email applications that can be downloaded for free at www.sun.com.
To make the email client required an order to be able to access SMTP, POP3, and IMAP. SMTP is a protocol to be able to send email. While POP3 and IMAP are protocols to be able to download email messages from the Mail Server.
To send a message use the following command:



In the above listing can be seen that done by sending an email calling new Mime Message class in Java Mail library. Object of the class to fill the properties of data such as email subject, email messages, and Date. Then the object of Mime Message sent by calling the transport method.
Meanwhile, to download the messages to look the this listing as follows:

Meanwhile, to connect to the Mail Client is as follows:



Described in the above listing that the input in order to connect to the Mail Server, in the pages that have been in connection input of the user, the insert into the String Buffer. Then the connection is done by making Store object and then the object is to connect with the save and send the session that contains the properties to the port SMTP authentication, POP3, IMAP and.
