3DES - Php crypto codes 2 Java codes convertion problem

Question

I give all php and java codes I convert one by one but I didnt get same result where is my mistake and what shall I do. Thanks for all.
Php Code
$key = "db9ca45ee012dcabaff193ca";
$input = sha1("MehmetKaraman");
$td = mcrypt_module_open('tripledes', '', 'ecb', '');
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND);
mcrypt_generic_init($td, $key, $iv);
$encrypted_data = mcrypt_generic($td, $input);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
echo sha1(bin2hex($encrypted_data));
Output : d7eaa53ab43683a1323cfae877a24efb4a918411
Java Code :
String message= “MehmetKaraman”;
byte[] input = MessageDigest.getInstance("SHA1").digest(message.getBytes("utf-8"));
     final Cipher cipher = Cipher.getInstance("DESede/ECB/NoPadding");
     final SecretKey key = new SecretKeySpec("db9ca45ee012dcabaff193ca".getBytes("utf-8"), "DESede");
cipher.init(Cipher.ENCRYPT_MODE, key );
if( input.length % 8 != 0){
     byte [] in2 = new byte[input.length+ 8- input.length%8];
     for(int i = 0;i<input.length;i++){
     in2=input[i];
     input = in2;
     final byte[] encrypted_data = cipher.doFinal(input);
     System.out.println(bin2hex(MessageDigest.getInstance("SHA1").digest(bin2hex(encrypted_data).getBytes())));
Output : 626b61642ec4ba8f7467933832619d492a6fdde1

Answer 1

Either you need$input = sha1("MehmetKaraman", true);or in your Java you need to hex encode your sha1 digest before encrypting. When I do either of these and emulate your Java bin2hex() method I get a match.
I don't understand why people seem unable to do simple debugging. If you had read the PHP documentation for the sha1() function and had printed out the results at each stage it would have been obvious.
P.S. The zero padding implemented by your codeif( input.length % 8 != 0){
byte [] in2 = new byte[input.length+ 8- input.length%8];
for(int i = 0;i<input.length;i++){
in2=input[i];
input = in2;
}can be replaced by 1 line using one of the methods in class java.util.Arrays.
