Excellent questions. Keep in mind that because RSA encryption/decryption uses a public key and a private key, it is regarded as asymmetric cryptography.
Hi MosheTreutel99 ,
Great questions. Note that RSA encryption/decryption is considered asymmetric encryption as it involves a pubic key and private key. Symmetric encryption is when both sides are using the same key. AES is a good example of this.
There is a theory section at the bottom of this page: https://asecuritysite.com/rsa/ speed stars . There are also lots of references to further topics at that link.
