I code for fun, mostly self taught, both high and low level. Also self taught in various aspects of information security. Love the puzzles.

comment Why RSA can't handle numbers above 76?
To be technically correct, it works fine, except there are multiple possible decryption for each character and it's non-deterministic to know which it is.

@yozloy that's more for security, the larger the primes the harder it is to factorize, technically you could use single digit primes, but it'll be trivial to break the keys, something is still wrong with the math here, this expression must hold true: %n !>= n . The only thing I can think of causing an issue is an order of operations error somewhere possibly due to optimization or something. Which programming language is it (I can think of several which have close enough syntax).

comment ABC Conjecture's Impact on RSA Encryption
Actually, sailboats and flying cars have a few more links than that. Aerodynamics and hydrodynamics are very similar and both are important on a sailboat.

comment Is there a way to make RC4 (ARCFOUR) secure, or is it completely broken?
I would point out initial key expansion for AES is also quite slow compared to other block ciphers.
