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. WebThis is the NTRU encryption algorithm.
