i need a small desktop application (.exe file, for Windows) to do the following. 1. open a .csv file (via file-open dialog) 2. take an input of secret_key and secret_iv (see below) 3. take an input of the "save-as" 4. encrypt the first column of CSV and put it as last column (see how many columns there are, add one more column) 5. save the newly generated CSV (original with 1 added column) in given location. 6. when i close and reopen the program - it should come back with pre-filled secret_key and secret_iv here is the encryption code in PHP, translate it to the language you use function myCrypter($string, $secret_key, $secret_iv) { $encrypt_method = "AES-256-CBC"; $key = hash('sha256', $secret_key); $iv = substr(hash('sha256', $secret_iv), 0, 16); $output = base64_encode(openssl_encrypt($string, $encrypt_method, $key, 0, $iv)); $output = str_replace(['+', '/', '='], '', $output); return $output; } PHP: if everything is done correctly - with following keys: $secret_key = 'gh356u%#^uj3h5^hertj68eujJUfr'; $secret_iv = 'I^57ki$^7i#%i3hjryjt'; the encrypted version of 'hello world' will be: V1U1b3E2OGpJY3JtRmtKU3N4TER2Zz09 please PM me with your price. Payment is paypal as soon as i receive the working version.
