[PHP] Encrypt data to base for authentication...
Hi Fellas, I am trying to figure out how to encrypt the data using the base only. The webserver use the base authentication. I have been searching the PHP manual and I only saw base64_encode() but it is not the right algorithm. Does anyone know the php function for the Base encryption?

[PHP] encrypt data with pgp
Hello everyody, I search to encode a string with a strong alogrythm. I choose pgp my desktop is a windows computer; I have found a function but I can't use it because on windows, pgp cant encrypt on commandline. have you found something for windows station? your help will be helpfull. greetings _ GRAND JEU SMS : Pour gagner un NOKIA 7650, envoyez le mot IF au 61321 (prix d'un SMS + 0.35 euro).

Fw: [PHP] encrypt data with pgp
just for explain me another better: if I had post in this mailing list, it's
just because I want to find another way to use this function under windows
system
function pgp_encrypt($keyring_location, $public_key_id, $plain_text) {
$key_id = EscapeShellArg($public_key_id);
putenv(PGPPATH=$keyring_location);
// encrypt the message
$pipe = popen(pgpe -r $key_id -af, r);
fwrite($pipe, $plain_text);
$encrypted_text = '';
while($s = fgets($pipe, 1024)) {
// read from the pipe
$encrypted_text .= $s;
}
pclose($pipe);
return $encrypted_text; }
thanks for the tip on winPT, I will try it and will post the code of the
function I will developp if some are interest in...

Re: [PHP] Encrypt data...
Aww! Neat! That look better than the one I came up with. Thanks for your
time on this one.

Here is a simple class for encoding and decoding:
class encrypt_class{
var $secret;
function encrypt_class(){
$this-secret = 'this is a very long key, even too long
for the cipher';
}
Function encode($id){
$eid = $iv = 0;
$len = strlen($id);
$id = $len.'-'.$id;
$td = mcrypt_module_open(MCRYPT_TripleDES, ,
MCRYPT_MODE_ECB, );
$key = substr($this-secret, 0, mcrypt_enc_get_key_size
($td));
$iv = pack(a.mcrypt_enc_get_iv_size($td),$iv);
mcrypt_generic_init ($td, $key, $iv);
$eid = base64_encode(mcrypt_generic ($td, $id));
mcrypt_generic_deinit($td);
return $eid;
}
Function decode($eid){
$id = $iv = 0;
$td = mcrypt_module_open (MCRYPT_TripleDES, ,
MCRYPT_MODE_ECB, );
$key = substr($this-secret, 0, mcrypt_enc_get_key_size
($td));
$iv = pack(a.mcrypt_enc_get_iv_size($td),$iv);
mcrypt_generic_init ($td, $key, $iv);
$id = mdecrypt_generic ($td, base64_decode($eid));
$len = strtok($id,'-');
$id = substr($id,(strlen($len)+1),$len);
mcrypt_generic_deinit($td);
return $id;
}
}
Usage
?
$word = 'Hello';
$e = new encrypt_class();
$encrypted = $e-encode($word);
echo encrypted = $encrypted br;
$decrypted = $e-decode($encrypted);
echo decrypted = $decrypted br;
if($word == $decrypted){
echo They match br;
}
else{
echo Oops they don't match br;
}
?

Well, I meant a script. I do have mcrypt but I don't feel comfortable with that becuase if I upgrade PHP or Mcrypt, then it could affected the encrypt data.
