Which encryption algorithm is stronger for transferring large text files?

Question

Encryption

Symmetric cipher. or combined cipher. (symmetrical + asymmetric). I myself think that the second option is correct, but honestly I do not understand much.

Answer 1

For large text files, it is much more important to pre-compress them ...

Answer 2

Cryptographic strength

Answer 3

The strength of the cipher is determined not only by the algorithm, but also by the length of the key. For example, AES-256 encryption is more secure than RSA 512.
Typically, large amounts of data are encrypted with a symmetric algorithm, since it is much faster than an asymmetric one (with comparable cryptographic strength).
But how to exchange keys is a separate issue. It depends on various parameters, such as who sends where. If you are transferring files from one computer to another (that is, you have only 2 exchange participants), then you can get by with a simple shared key. If there are many participants in the exchange, then an asymmetric algorithm can be used for key exchange.
