Are you Devil?
Actually, this has been discussion for over 6 months in both public groups and private discussions. Most of you know/heard about me from BitShares and Steem Blockchains, probably, as authentic asshole unto ignorant ones, as my profile says obviously :) Some will say worst about me, some will cheer up my nickname up to the Sky. I'm not any of what they are saying probably... but, it's not up to me to analyze myself or to be realistically objective on that topic :) So, here we go...
My colleagues from real life, blockchain, associates or even friends and family are keep asking me why I'm presenting myself as a Devil/Evil if i'm not and do I know how it actually leaves impression to others or even affects my business reputation. To be honest, i did become a Devil/Asshole around, but not because I was one already or am one, but because of people who were saying/asking and reviving Gates of Hell and what else not...
So, to disappoint few individuals who worship Devil and more of them who are scared from it, I'm not a Devil, and true meaning of IT Devil you can read up below :)
Lucifer aka "Cipher"
"In cryptography, Lucifer was the name given to several of the earliest civilian block ciphers, developed by Horst Feistel and his colleagues at IBM. Lucifer was a direct precursor to the Data Encryption Standard. One version, alternatively named DTD-1, saw commercial use in the 1970s for electronic banking." - Source: Google.com
Short Overview
"LUCIFER uses a combination of Transposition and Substitution crypting as a starting point in decoding ciphers. One variant, described by Feistel in 1971, uses a 48-bit key and operates on 48-bit blocks. The cipher is a Substitution-permutation network and uses two 4-bit S-boxes. The key selects which S-boxes are used. The patent describes the execution of the cipher operating on 24-bits at a time, and also a sequential version operating on 8-bits at a time. Another variant by John L. Smith from the same year uses a 64-bit key operating on a 32-bit block, using one addition mod 4 and a singular 4-bit S-box. The construction is designed to operate on 4 bits per clock cycle. This may be one of the smallest block-cipher implementations known. Feistel later described a stronger variant that uses a 128-bit key and operates on 128-bit blocks.
Sorkin (1984) described a later Lucifer was a 16-round Feistel network, also on 128-bit blocks and 128-bit keys. This version is susceptible to differential cryptanalysis; for about half the keys, the cipher can be broken with 236 chosen plaintexts and 236 time complexity.
IBM submitted the Feistel-network version of Lucifer as a candidate for the Data Encryption Standard (compare the more recent AES process). It became the DES after the National Security Agency reduced the cipher's key size to 56 bits, reduced the block size to 64 bits, and made the cipher resistant against differential cryptanalysis, which was at the time known only to IBM and the NSA.
The name "Lucifer" was apparently a pun on "Demon". This was in turn a truncation of "Demonstration", the name for a privacy system Feistel was working on." - Source: Wikipedia

It all makes sense now. You aren't the devil, just a smart dude!

This was very interesting and enlightening. Thank you for sharing this information. But I will say, I always thought that was your moniker because you bring light to dark nodes and ignorant minds. Which, in addition to the above, is entirely accurate. :)

Lucifer Luxifer is to light what an aquifer is to water.
