What is a cryptosystem? Definition from WhatIs.com

WebCryptanalysis refers to the study of ciphers, ciphertext , or cryptosystems (that is, to secret code systems) with a view to finding weaknesses in them that will permit retrieval of the plaintext from the ciphertext, without necessarily knowing the key or the algorithm . This is known as breaking the cipher, ciphertext, or cryptosystem. WebNov 30, 2024 · RSA encryption is a public-key cryptosystem technology that employs the RSA algorithm. The world runs on communications. From ledger checking and balancing to pen-pals, everyone has a need to transmit information.
