Block ciphers

FROG

In cryptography, FROG is a block cipher authored by Georgoudis, Leroux and Chaves. The algorithm can work with any block size between 8 and 128 bytes, and supports key sizes between 5 and 125 bytes. The algorithm consists of 8 rounds and has a very complicated key schedule. It was submitted in 1998 by TecApro, a Costa Rican software company, to the AES competition as a candidate to become the Advanced Encryption Standard. Wagner et al. (1999) found a number of weak key classes for FROG. Other problems included very slow key setup and relatively slow encryption. FROG was not selected as a finalist. (Wikipedia).

Why Frog Tongues Are The Ultimate Weapon

A frog’s tongue can catch flies faster than you can blink. It shoots out of its mouth colliding with the fly, covering it in some of the stickiest spit on Earth. That mucus is so strong, the frog can lift 1.4 times its body weight, the equivalent of a human lifting up a refrigerator with i
