RSA 2/4

Crypto

Challenge

DESCRIPTION Let's kick it up a notch. Bob generated these RSA parameters and was certain that his encryption would be unbreakable because his smartest friend (John) couldn't crack it. Is it truly secure?

Download vals.txt and decrypt the value of c given all the other params.

Author: lord_idiot

ATTACHED FILES vals.txt

Solution

Use factordb to get p and q.

p = 757797040104296557573809656933
q = 927584008074066047910168872563
