WebMar 30, 2024 · Viewed 971 times. 2. I'm trying to solve a CTF problem relating to RSA encryption. I can run a challenge binary that will read a flag from a file, the flag will match the following RegEx: AB1234C\ { [0-9a-f] {32}\}\n. So in total the flag is 42 bytes including the newline. The flag is then padded with random padding to a total of 128 bytes. WebOct 18, 2024 · Specific RSA challenge. It was a challenge from CTF (ended), but I didn't solve it. p, q = keygen (512) n = p * q flag = bytes_to_long (flag) enc = pow (n + 1, flag, n**3) So we have module and encrypted flag.
