Answer 1

Based on @inieto answer i created two simple classes for encryption and decryption one for php and one for typescript that are easy to use. https://github.com/5imun/Endecryptor Just include/import them and you are ready to go. Example for php:

#Include Endecryptor before using it
$secret = 'hxXxVEVNa3S6OQdgltNoDkbZ10b0MkQV';
$method = 'AES-256-CBC';
$valid_request_TS_interval = 100; # in seconds
$endecryptor = new Endecryptor($secret, $method, $valid_request_TS_interval );

$original_message = '{"test":"Hello, World!"}';
$endecryptor->encryptWithTS($original_message);

echo "Encrypted message: $endecryptor->temp_encrypted\n";
echo "Encrypted message hmac: $endecryptor->temp_hmac\n";

if ( $endecryptor->decryptAndValidateTS( $endecryptor->temp_encrypted, $endecryptor->temp_hmac ) ) {
  echo "Original message:  $original_message\n";
  echo "Decrypted message: $endecryptor->temp_decrypted\n";
} else {
  echo 'Description was not successful';
}

Result:

Encrypted message: MjliMmM5NzljYWQ0YjA4Mw==ULxsH1juCOrieEkiRpHY1CMkKtvSvB5X+b8E9cOcQ7yYt+SUKj+I6FjaGvYjEldt
Encrypted message: hmac: 5aa8f1b268dfef0dc2f48f1a25204e82
Original  message:  {"test":"Hello, World!"}
Decrypted message: {"test":"Hello, World!"}
