| Mar 11, 2020 at 19:31 | comment | added | JMP | @MichaelHardy; I found too many errors in it, so I'm going to look at it over the week, maybe even come up with a fancy name! Thanks for the MathJax tip. | |
| Mar 11, 2020 at 19:20 | comment | added | Michael Hardy | @jmp $$ _\pi U_n=\bigcup_t \;_\pi U_n(t) $$ First time someone deleted a posting within seconds after I corrected a typesetting issue in it. But for future reference you may want to know that among the advantages of \bigcup over \large\cup are the positions of the subscripts and superscripts, as in $\displaystyle \bigcup_{n=1}^\infty, $ etc. (Besides the other advantages.) $\qquad$ | |

| Jan 28, 2020 at 15:21 | comment | added | Aravind A | Thankyou, that's the same reason why I felt it should be posted it here. I am very much happy with your explanation. By the way can you please tell me how you calculated that there are 2 raised to 256 pairs for any given c ? | |

| Jan 28, 2020 at 15:00 | comment | added | Aravind A | Thankyou very much for your answer ! How can I move this question to get more answers from there regarding crypto? | |
| Jan 28, 2020 at 14:56 | comment | added | JMP | That's a good question for crypto.stackexchange.com. | |
| Jan 28, 2020 at 14:55 | comment | added | Aravind A | Is it wise to use this a good crypto system ? | |
