The age utility is a bit ironic in that a utility intended to make malicious modification less of a problem doesn't do signatures. So an attacker doesn't have to go to the bother to modify the file, they can just create a whole new file. Kryptor is more complete. If you do public key encryption you also have to support signatures if modification is an issue. You can't just leave it to the user to figure out.
