| Jul 18, 2016 at 21:13 | comment | added | e-sushi | @David天宇Wong Yeah, I quickly realized that too then in 2013 when I asked the question. It also quickly dawned upon me that it wasn’t even the same kind of key I was comparing there. All in all, I guess you could call this “one of my oldschool self-facepalm moments” which I probably would have killed a long time ago… if it weren’t for @Pornin’s superb answer which might (or might not) help others in one way or another. | |

Added year as time has passed and it makes it easier for readers to grasp which year was meant. Added two tags while I was at it.

| Oct 1, 2013 at 19:08 | comment | added | user4982 | Originally NIST was intending to disallow 1024-bit keys back in 2010. Discussion between NIST and other government agencies found out that it is not viable alternative from cost perspective and that the agencies are not currently ready. NIST decided to postpone transition until 2013, and it is due soon. The transition affects many other algorithms as well, like DSA, ECDSA, ... Read SP 800-131A for details. The SHA-3 has next to nothing to do with this, except that SHA-1 is get deprecated. But, SHA-2 already exists and is ok. | |
