Intro to Cryptography

This whole question is just one question as per Chegg policy.

2. Compare and contrast the following two encryption systems. Would they have a similar result or a different result? Would any of the decryption methods that we have covered (individually or in combination) be applicable to either system? (i) First perform a Vigenre cipher and then perform a general substitution on the Vigenre ciphertext (ii) Determine a keyword, perform a general substitution on the keyword, and then use the encrypted keyword to perform a Vigenre cipher 2.
