Factorization of 512 and 1024 bit numbers
I have been given cryptography task in university. I need to factorize 2 numbers - one 512 bit and one 1024 bit and i have about a day for till deadline.
I tried at first MSIEVE, but it need about several weeks to factorize 512 bit number.. Last night i tried to check modulo my number to prime numbers - from sqrt(my_number) and go on..
This attempt failed too - it will take too much time.
Can You help me with any ideas to meet the deadline..
Thanks a lot.
