All key and messages are set SensitiveParameter type
On end, unset the key parameter with sodium mem zero
Get/Compare key set methods
Additional check on empty key
Add missing sodium mem zero for inner function variable clean up
Move Passwords from Check to Security and deprecate old
Add new SymmetricEncryption and CreateKey
CreateKey class just creates keys for the SymmetricEncryption
SymmetricEncryption uses the hex2bin calls to convert the hex key to the
internal binary key
Example:
$key = CreateKey::generateRandomKey();
$encrypted = SymmetricEncryption::encrypt($string, $key);
$decrypted = SymmetricEncryption::decrypt($encrypted, $key);
Above $key must be stored in some secure location (.env file)
