SIGABA, otherwise known as ECM Mark II, was used by the United States for message encryption during WW2 up to the 1950s. It was developed in the 1930s by the US Army and Navy, and has up to thiTypexEncipher/decipher with the WW2 Typex machine. Typex was originally built by the British Royal Air Force prior to WW2, and is based on the Enigma machine with some improvements made, including using five rotors with more stepping points and WhirlpoolWhirlpool is a cryptographic hash function designed by Vincent Rijmen (co-creator of AES) and Paulo S. L. M. Barreto, who first described it in 2000. Several variants exist: Whirlpool-0 is the original version released in 2000. Whirlpool-T
