Forget safe primes... Here, we like to live life dangerously... >:)
Searching online for "pollard smooth prime" finds .
Using with the pollard_p_1
attack by running python RsaCtfTool.py --uncipher [c] -e 65537 -n [n] --attack pollard_p_1
doesn't work since it doesn't try enough primes (). So, we adapt their script to create the solution , which tries 7000 primes.
Interestingly, this prime is in factordb so will print the flag immediately when using the factordb
attack.
