Article source : https://www.warpcond...el-256-and-cbc/ Requirement: PHP 5.3 + Use the following code In Phprunner, After Application Initialized:
// Define a 32-byte (64 character) hexadecimal encryption key
// Note: The same encryption key used to encrypt the data must be used to decrypt the data define('ENCRYPTION_KEY', 'd0a7e7997b6d5fcd55f4b5c32611b87cd923e88837b63bf2941ef819dc8ca282'); // Encrypt Function
function mc_encrypt($encrypt, $key){
$encrypt = serialize($encrypt);
$iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_CBC), MCRYPT_DEV_URANDOM);
$key = pack('H*', $key);
$mac = hash_hmac('sha256', $encrypt, substr(bin2hex($key), -32));
$passcrypt = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $encrypt.$mac, MCRYPT_MODE_CBC, $iv);
$encoded = base64_encode($passcrypt).'|'.base64_encode($iv);
return $encoded;
} // Decrypt Function
function mc_decrypt($decrypt, $key){
$decrypt = explode('|', $decrypt.'|');
$decoded = base64_decode($decrypt[0]);
$iv = base64_decode($decrypt[1]);
if(strlen($iv)!==mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_CBC)){ return false; }
$key = pack('H*', $key);
$decrypted = trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key, $decoded, MCRYPT_MODE_CBC, $iv));
$mac = substr($decrypted, -64);
$decrypted = substr($decrypted, 0, -64);
$calcmac = hash_hmac('sha256', $decrypted, substr(bin2hex($key), -32));
if($calcmac!==$mac){ return false; }
$decrypted = unserialize($decrypted);
return $decrypted;
}
Note:
- Use your own Hex for ENCRYPTION KEY. You can generate Hex from here : http://www.andrewsco...m/tools/wep.asp
- In your database, make sure your field size is enough to store encrypted data (varchar, 180 or 200 is enough)
In PHPRunner Events : Add Page: Before Record Added
Edit Page: Before Record Updated
Import Page: Before insert Record
Use the following code to encrypt data:
$values["YOUR_FIELD_NAME"] = mc_encrypt($values["YOUR_FIELD_NAME"], ENCRYPTION_KEY); [color="#0000ff"]Print Page: Before Record Processed [color="#0000ff"]Export Page: Before [size="2"]Export [/size][size="2"]Record [/size]
Use the following code to decrypt data:
$data["YOUR_FIELD_NAME"]=mc_decrypt($data["YOUR_FIELD_NAME"], ENCRYPTION_KEY);
