Is RC4 asymmetric or symmetric?

I have been studying and thinking about the RC4 stream cipher for a couple of days.

It seems like there are many variants on how RC4 works, such as symmetric or asymmetric, some with keys, and others not.

For example, if RC4 is symmetric, then the key is the same for both encrypt and decrypt. Does that mean that RC4 uses one key for each message? How would RC4 work if it was asymmetric? Also, does the use of multiple keys weaken RC4? For example, if the first key was used to encrypt messages, and the second key was used to decrypt them. RC4 is asymmetric. RC4 is a stream cipher. As such, it is very fast and easy to use. However, the encryption/decryption of an entire message requires a lot of CPU power (not to mention the time and the size of the generated keystream). Thus, this is not something that should be done in real-time applications. This means that the data must be split into blocks, which is known as mode-of-operation.

If RC4 is symmetric, then the key is the same for both encrypt and decrypt. Yes, RC4 is symmetric. You need a secret key to be able to encrypt and decrypt a message.

If you use a block cipher, then each block needs a secret key. However, if you use a stream cipher, then each key is only needed for a single message. The keystreams for all messages that are encrypted at the same time are generated with the same key.

If you use a block cipher, then the mode-of-operation determines how the blocks are processed. If the mode-of-operation is ECB, then the blocks are encrypted in a plaintext block-by-block fashion. If the mode-of-operation is CBC, then the blocks are encrypted in a cipher-block-by-block fashion.

For RC4, the mode-of-operation is CFB, so the blocks are encrypted in a cipher-block-by-block fashion.
