Re: [PHP] can I compile php source

I can't believe you can spend so much energy on this flame/agrovated
response crap when a small amount of that energy would have simply answered
this guys question.

No wonder there is so much war. Mostly started by people who know how to be
self sufficient. Don't worry. In 100 years we will all be dead, maybe the
next generation will actually learn something John.

Richard,

Thanks for your help.

The code (as I mentioned) was not mine. I did however find the example from
the link you sent me to and followed that. It works quite well.

Again, thanks for your time.

Darren

 Where did you call srand() as the manual says you should?
 http://php.net/mcrypt_create_iv

  mcrypt_generic_init ($td, $key, $iv);

 Why are you not checking your error codes here?
 This function alone has -3, -4, and unknown error codes you should be
 checking.

 *EVERY* function with a documented error code return mechanism needs you
 to write code to *CHECK* that return code.

 You'll find a *TON* of things out a lot faster if you write that extra few
 lines of code for each function call.

  $encrypted_data = mcrypt_generic ($td, $input);
  mcrypt_generic_deinit ($td);
  mcrypt_module_close ($td);
  return trim(chop(base64_encode($encrypted_data)));
  }
 
  //$input - stuff to decrypt
  //$key - the secret key to use
 
  function _mdecrypt($input,$key)
  {
  $input = str_replace(\n,,$input);
  $input = str_replace(\t,,$input);
  $input = str_replace(\r,,$input);
  $input = trim(chop(base64_decode($input)));
  $td = mcrypt_module_open ('tripledes', '', 'ecb', '');
  $key = substr(md5($key),0,24);
  $iv = mcrypt_create_iv (mcrypt_enc_get_iv_size ($td),
  MCRYPT_RAND);
  mcrypt_generic_init ($td, $key, $iv);
  $decrypted_data = mdecrypt_generic ($td, $input);
  mcrypt_generic_deinit ($td);
  mcrypt_module_close ($td);
  return trim(chop($decrypted_data));
  }
  main();

[PHP] Re: Encryption

2004-12-20 Thread Darren Wheatley

If nobody has a better suggestion I am simply going to do a reverse check
and for those that fail implement a massive hack. I really don't want to do
that...

Please, if you have any ideas give me a yell?
