The intelligence gleaned from this source, codenamed "Ultra" by the British, was a substantial aid to the Allied war effort.Though Enigma had some cryptographic weaknesses, in practice it was German procedural flaws, operator mistakes, failure to systematically introduce changes in encipherment procedures, and Allied capture of key tables and hardware that, during the war, enabled Allied cryptologists to succeed and "turned the tide" in the Allies' favour.The Poles had six bomby, but when the Germans added two more rotors, ten times as many bomby were needed, but the Poles did not have the Pyry near Warsaw, the Poles initiated French and British military intelligence representatives into their Enigma-decryption techniques and equipment, including Zygalski sheets and the cryptologic bomb, and promised each delegation a Polish-reconstructed Enigma.Consequently, the Polish mathematicians were able to build their own Enigma machines, which were called Enigma doubles.Rejewski was aided by cryptanalysts Jerzy Różycki and Henryk Zygalski, both of whom had been recruited with Rejewski from Poznań University.I've been looking over the docs for the crypto module in Node, and I'm trying to figure out how to set the padding when doing symmetric encryption. I can't see anywhere that it allows you to specify padding.I would certainly hope this is possible to do using this library.

During the war, British cryptologists decrypted a vast number of messages enciphered on Enigma. I'm about to embark on journey that may change my career by doing a rather big project this time.I have experience in cryptography as I have taken several courses and written my own implementation of some algorithms (DES, AES, Schnorr) but I have never used any complete library for it.The German firm Scherbius & Ritter, co-founded by Arthur Scherbius, patented ideas for a cipher machine in 1918 and began marketing the finished product under the brand name Enigma in 1923, initially targeted at commercial markets.With its adoption (in slightly modified form) by the German Navy in 1926 and the German Army and Air Force soon after, the name Enigma became widely known in military circles.
