comment Calculating amount of time for brute forcing ciphertext depending on the size of the key
There were a number of different types of Enigma machines; however I don't believe any of them came anywhere close to transforming the plaintext in $2^{77}$ possible different ways; I get closer to $2^{30}$ (assuming the 4-rotor Naval variant)

comment Which is better ECDHE with TLS 1.0
@tylo: nit: AES-128 and AES-256 has the same block size; they differ in the size of their keys.

comment Multiplicative inverse in $GF(2^8)$?
Actually, log and antilog are tables that you build (or initialize); they're uint8_t log[255], antilog[255]; (and, come to think about it, in C, log isn't the best name; it conflicts with the log() function within math.h). You initialize those tables as above (possibly using your multiplication routine to generate the initial antilog entries)

comment Recovery of RC4 key when S-box 0 stage or 1st stage known
I have no idea what 'state of S is 1' means.
