PHP - Is There An Equivalent To Java Cast To Byte In Php?

Hi All,

Am trying to decrypt a key encrypted by Java Triple DES function using PHP mcrypt function but with no luck. Find below the java code

Code: [Select]
package com.wipro;

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;


public class Encrypt3DES {

private byte[] key;
private byte[] initializationVector;

public Encrypt3DES(){

}

public String encryptText(String plainText, String key) throws Exception{
     
//----  Use specified 3DES key and IV from other source --------------
byte[] plaintext = plainText.getBytes();
byte[] myIV = key.getBytes();
byte[] tdesKeyData = {(byte)0xA2, (byte)0x15, (byte)0x37, (byte)0x08, (byte)0xCA, (byte)0x62,
(byte)0xC1, (byte)0xD2, (byte)0xF7, (byte)0xF1, (byte)0x93, (byte)0xDF,
(byte)0xD2, (byte)0x15, (byte)0x4F, (byte)0x79, (byte)0x06, (byte)0x67,
(byte)0x7A, (byte)0x82, (byte)0x94, (byte)0x16, (byte)0x32, (byte)0x95};

Cipher c3des = Cipher.getInstance("DESede/CBC/PKCS5Padding");
SecretKeySpec    myKey = new SecretKeySpec(tdesKeyData, "DESede");
IvParameterSpec ivspec = new IvParameterSpec(myIV);
   c3des.init(Cipher.ENCRYPT_MODE, myKey, ivspec);
byte[] cipherText = c3des.doFinal(plaintext);
sun.misc.BASE64Encoder obj64=new sun.misc.BASE64Encoder();
return obj64.encode(cipherText);
 
  }
   
  public String decryptText(String encryptText, String key) throws Exception{


byte[] initializationVector = key.getBytes();
byte[] tdesKeyData = {(byte)0xA2, (byte)0x15, (byte)0x37, (byte)0x08, (byte)0xCA, (byte)0x62,
(byte)0xC1, (byte)0xD2, (byte)0xF7, (byte)0xF1, (byte)0x93, (byte)0xDF,
(byte)0xD2, (byte)0x15, (byte)0x4F, (byte)0x79, (byte)0x06, (byte)0x67,
(byte)0x7A, (byte)0x82, (byte)0x94, (byte)0x16, (byte)0x32, (byte)0x95};

       
  byte[] encData = new sun.misc.BASE64Decoder().decodeBuffer(encryptText);
  Cipher decipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");
  SecretKeySpec myKey = new SecretKeySpec(tdesKeyData, "DESede");
  IvParameterSpec ivspec = new IvParameterSpec(initializationVector);
  decipher.init(Cipher.DECRYPT_MODE, myKey, ivspec);
  byte[] plainText = decipher.doFinal(encData);
  return new String(plainText);

}


}


Kindly help me find out an equivalent PHP code to decrypt.

Hi all,

I've just started upgrading from procedural style mysql statements to object orientated style mysqli prepared statements. I was just hoping someone could look over my registration page statement code and tell me if there are any bits that are unecessary or a security issue (All of the code does already work - just want it checking)

The reason I would like them checked over is because I've never touched OOP or mysqli in my life as I haven't been doing php all that long. I've had my own mysql statements running great for a couple of years but I want to keep with the times! If they are ok, then I'll go on to convert the remainder of the site

First of all I include the mysqli database connection script before each mysqli statements (as php auto drops the connection once the script has finished - a little annoying as it increases the code. But I can see the resources advantages.  ):

../db/dbauth.php (outsite www root):
Code: [Select]
$mysqli = new mysqli($hostname_lh, $username_lh, $password_lh, $database_lh);

if (mysqli_connect_errno()) {
$mess = "There was a mysqli connection error! Mysqli Error: " . mysqli_connect_error();
$contact_email = "webmaster@website.com";
$message_sub = "Mysqli Connection Error";
$hdrs = "From: " . $contact_email . "\r\n";
$hdrs .= "Reply-To: ". $contact_email . "\r\n";
$hdrs .= "MIME-Version: 1.0\r\n";
$hdrs .= "Content-Type: text/html; charset=UTF-8\r\n";
mail($contact_email, $message_sub, $mess, $hdrs);
exit();
}

The above will send an email if there are any connection problems. This file has to be called before each mysqli statement... is there an easier way of doing this? I don't want to have it in my file as it contains the password/database details. Do I have to include the file each time I use mysqli in a file as I have been doing? Some files contain upto 4-5 mysqli statements, so i'm effectively including the dbauth.php file 4-5 times.

Anyways to the statements:

First prepared statement is for populating a countries drop down box:
Code: [Select]
// connect to db for mysqli
require_once('../db/dbauth.php');

// populates countries drop down
$countrystmt = $mysqli->stmt_init();
if ($countrystmt = $mysqli->prepare("SELECT country FROM countries")){
$countrystmt->execute();
$countrystmt->bind_result($option);
while ($countrystmt->fetch()) {
// records stored in $option
echo "<option value='" . $option . "'";
if ($user_country == $option) {
echo " selected";
}
echo ">" . $option . "</option>";
}
$countrystmt->close();
}
$mysqli->close();

This one checks the db to see if the user already exists:
Code: [Select]
// connect to db for mysqli
require_once('../db/dbauth.php');

// checks if the username is in use
$result = $mysqli->stmt_init();
if ($result->prepare("SELECT their_username FROM users WHERE their_username=?")){
$result->bind_param("s", $their_username);
$result->execute();
$result->store_result();
$row_count = $result->num_rows;
$result->close();
}
// if query errors sends an email
$mysqli->close();

// if the name exists it gives an error
if ($row_count != NULL) { //..... .... ....


next one inserts a new user into the db (after some santitising of inputs):
Code: [Select]
// connect to db for mysqli
require_once('../db/dbauth.php');

// inserts a new user
$null = NULL;
$insert_stmt = $mysqli->stmt_init();
if ($insert_stmt->prepare("INSERT INTO members VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)")) {
$insert_stmt->bind_param('issssssssssssiiiiisiis', $null, $user_name, $user_companyname, $user_email, $user_1stline, $user_address2, $user_town, $user_county, $user_postcode, $user_country, $user_tel, $their_username, $null, $zero, $zero, $zero, $zero, $zero, $user_serial, $zero, $zero, $zero);
$insert_stmt->execute();
$insert_stmt->close();
}

// if query errors sends an email
if ($mysqli->error) {
try {   
throw new Exception("MySQL error $mysqli->error <br> Query:<br> $query", $mysqli->errno);   
} catch(Exception $e ) {
$mess = "Error No: ".$e->getCode(). " - ". $e->getMessage() . "<br >";
$mess .= nl2br($e->getTraceAsString());
$contact_email = "webmaster@website.com";
$message_sub = "Mysqli Registration Query Error [UAU01]";
$hdrs = "From: " . $contact_email . "\r\n";
$hdrs .= "Reply-To: ". $contact_email . "\r\n";
$hdrs .= "MIME-Version: 1.0\r\n";
$hdrs .= "Content-Type: text/html; charset=UTF-8\r\n";
mail($contact_email, $message_sub, $mess, $hdrs);
}
header("refresh: 10; registration.php");
die('ERROR: Unable to add you as a new user. Please report this error to us using our contact us form.<br><br>We will redirect you back to the registration form in 10 seconds.<br><br><div style="margin: auto; text-align: center;"><img src="http://static.website.com/images/loading.gif" alt="loading"></div>');
exit();
}
$mysqli->close();

If the script above errors then it will send an error email to the webmaster (me) and also give a friendly error to the user before redirecting back to a registration page.

I've got a similar error and refresh method for the other statements further up, but didn't think I should overload everyone with loads of similar code! 

Anyways,  muchos help always appreciated!!!

Anyone know how to cast arabic numeric input to (int) ?
Or how to convert arabic numerals to english numerals?
I created an auction website, inputting english numbers seems to work. However when I switch languages to Arabic, it doesn't work.
By casting any arabic numeral input to (int) It keeps returning 0.

i have a code in c# and here use GetBytes(msg) for SSlStream.write, here send and received data correctly, here all work fine, now i want to make the same event in php, but here i cant see a SslSteam or similar(i think no problem, becouse i working with socket_connection, and i think SSL is only for security), now for compare i stop the code in c# for see what data is sending and try to convert in php, for send here, i can see a data byte{} in c# and with `

$message=unpack('C*',$message);

` i can convert the string to byte[], comparing with c# value is the same so, here all is ok, my problem is when i try to write the request, becouse in SslStream.write accpet byte[] but socket_write no accept whe i try send `

socket_write($socket, '\n', strlen($message))

` i have a error : socket_write() expects parameter 2 to be string and obvius is becouse socket_write() only accept string, but so.. as i can send my byte[], becouse the server only accept a byte[] please help me

Dear all,

I'm trying to build an application to retrieve PDF documents from a site. The document being there is byte-served, so that I'm not able to get the complete document.

When i do a curl get for the document I get only the below.

In firebug, I could see three GET requests. First one has the status '302 Found'. Second and third has status as '206 Partial Content'.

How to get the complete file in this case. Or guide me, if I'm doing it in a wrong way.
