How to determine the encryption scheme used when issuing ciphertext and key

Question

For homework, I am asked to determine the algorithm used to generate the given ciphertext. A key is also given. I am currently studying a list of simple encryption algorithms and a half-blind test of various decryption methods in an attempt to obtain this simple text.

Is there a better way to do this process? I read the Google results pages on this topic and have not come across anything that would explain a better process than what I am already doing. So far, I have performed several levels of linguistic analysis using encrypted text and am trying to incorporate logical values ​​into an encrypted message in order to decrypt it.

It is built around basic cryptographic systems, nothing at the level of public key encryption or DES.

Even if I can get the original message, how will the encryption scheme used be displayed?

Answer 1

My answer would be that there is nothing wrong with trying different algorithms and see what works.
