WebAs we can notice from the code above, what happens on the server is: there are 100 stages, at each stage a string is composed by linking 3 randomly words together, where the words come from a list of them read by an external file; the string is then encrypted in some way and finally sent back. WebThe logic is very simple, read the flag and repeat 30 times for the ciphertext. Randomly take p and q, generate a public key, write pubkey.pem, encrypt it with the ext_rsa_encrypt function in the script, and finally write the ciphertext to flag.enc.. Try decryption, suggest that the ciphertext is too long, and then look at the encryption function.
