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.
