AES is more advanced and very secure so I would advise to with AES. I assume that you meant.

DSA - you need digital signature to encrypt.
AES - you have to have private/public pairs.

If you want more security then go for AES otherwise DSA should be fine.

There is no just encryption. You need to get an idea of your security schema, how you generate and distribute keys, and so on, otherwise the message could be decrypted by anyone, not by addressee, or not decrypted by addressee...

Please see my comment to the question. First of all, you need to grasp some ideas, at least the level of the user of cryptography, which is not trivial at all, so, from time to time, we observe the inquirers on this forum who even actually use the technology but still have no clue on the use of it. Don't become one of them, try to understand the topic. Start here:
https://en.wikipedia.org/wiki/Public-key_cryptography[^],
https://en.wikipedia.org/wiki/Cryptography[^].

Pay attention for what Alice and Bob do and why.
