With 1024 bit key I can represent a lot of values, would seem to be plenty. You have to use scientific notation for the number, 2^1024=1.797693134862315907729305190789e+308.
If you haven’t used scientific notation lately, you have to move the decimal place 308 places to the right inserting zeroes when you reach the “e”. That is a really big number! Unfortunately, with the steady growth of computing power, it will soon be not enough. Before that happens, it is important that internet security moves to the stronger 2048 bit.
How Do I Know if My Certs are 2048-bit?
Just go to the following page and you can generate a discovery report to see if their certs are 2048, and it’s free!
Action Required: What do I need to do?
If you own any 1024-bit certificates expiring this year, you must renew them by generating a 2048-bit or higher CSR. If you have certificates expiring in 2014 or later you need to replace and upgrade all 1024-bit certificates with 2048-bit. The deadline was October 1st, so if you have not done so you are past due!
