What is an asymmetric cryptosystem?

An asymmetric cryptosystem is one where different keys are employed for the operations in the cryptosystem (e.g., encryption and decryption), and where one of the keys can be made public without compromising the secrecy of the other key.

What is symmetric key encryption?

symmetric key encryption is when the cryptosystem uses the same key for both encryption and decryption. In this method, keys are shared with both parties prior to transmission and are changed regularly to prevent any system attacks. Asymmetric key encryption is when the cryptosystem uses different keys for encryption and decryption.

Are hybrid cryptosystems better than asymmetric only?

It's a common belief hybrid cryptosystems are better than asymmetric only. Is that allways like that? What's the benefit of using symmetric and asymmetric encryption for small data blocks (< 100 bytes)? Well, you're right about that.

How do cryptosystems encrypt data?

Cryptosystems are categorized by the method they use to encrypt data, either symmetrically or asymmetrically. symmetric key encryption is when the cryptosystem uses the same key for both encryption and decryption. In this method, keys are shared with both parties prior to transmission and are changed regularly to prevent any system attacks.
