SEED is a block cipher developed by the Korean Information Security Agency (KISA) and widely used in Korea. It is a 16-round Feistel cipher using two 8 by 8 S-boxes. SEED was not candidate in the AES competition. However, it uses 128-bit blocks and takes a 128-bit key, so it can be used as a drop-in replacement for AES-128 in many applications.
