AES
The most widely used symmetric block cipher standard in the world; it works with 128-bit blocks and 128/192/256-bit keys.
// EXPLANATION
Because AES is accelerated by dedicated hardware instructions it adds almost no overhead. It is used in most TLS connections, disk encryption and Wi-Fi security; there is no known practical break.
