The flag.zip contains the flag I am looking for but it is password protected. The password is the encrypted message which has to be correctly decrypted so I can useit to open the zip file. I tried using RSA but the zip doesn’t open by it. Can you help me get the flag please?
- RSA n分解
a.txt has a really small value of
n. The factors of this value can be brute-forced for directly and then an integer is obtained. The only file in
flag.txt which is password-protected. The password to this file is the integer which is obtained.
