I have a script with SHA256 encryption and Decryption.
Here is the Script.
Code: Select all
<?php
/* Body and code here */
public function shcEnDesDirS($locate,$method){
switch ($method) {
case '1':
rename($locate, $locate.".ext");
break;
case '2':
$locates = str_replace(".ext", "", $locate);
rename($locate, $locates);
break;
}
}
public function shcEnCry($key,$locate){
$data = file_get_contents($locate);
$iv = mcrypt_create_iv(
mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC),
MCRYPT_DEV_URANDOM
);
$encrypted = base64_encode(
$iv .
mcrypt_encrypt(
MCRYPT_RIJNDAEL_128,
hash('sha256', $key, true),
$data,
MCRYPT_MODE_CBC,
$iv
)
);
if(file_put_contents($locate, $encrypted )){
echo '....';
}else{
echo '....';
}
}
public function shcDeCry($key,$locate){
$data = base64_decode( file_get_contents($locate) );
$iv = substr($data, 0, mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC));
$decrypted = rtrim(
mcrypt_decrypt(
MCRYPT_RIJNDAEL_128,
hash('sha256', $key, true),
substr($data, mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC)),
MCRYPT_MODE_CBC,
$iv
),
"\0"
);
if(file_put_contents($locate, $decrypted )){
echo '....';
}else{
echo '....';
}
}
public function kecuali($ext,$name){
$re = "/({$name})/";
preg_match($re, $ext, $matches);
if($matches[1]){
return false;
}
return true;
}
}
/* rest of code here */
?>But I wanna know How can I use AES 256 with salt in this script instead of sha256?
Please.
Thanks in Advace..
