I am very new to cryptography and I am confused with something. Here is the homework question I am having trouble with:
Write a program to attack the Textbook RSA Encryption Scheme, in order to decrypt the encrypted file key_enc.txt which contains the 128 bits AES secret key together with the initialisation vector (IV) for Question 2.
You must explain and show how the attack is done.
The RSA parameters are as follows:
N: 92001629535369949668182190680140710002429961412439471184834723194899969898404162 82428855806975402440064473888135838545187330646754494062187654035542047167435016 34608863342073173012508616123265965429721791336874605919036975439595316606713189 21259313523852555003517715050369476348174980850810194157624985747443
My questions are:
- is it possible to use the formula in the link to find the answer with such a big value?
- inside the link, the plaintext value is given but the homework didn't provide a plaintext. Do I need to guess it?
