Meaning in The Context of Cryptography
In this meaning, a cryptosystem refers to a suite of algorithms needed to implement a particular form of encryption and decryption.
Typically, a cryptosystem consists of three algorithms: one for key generation, one for encryption, and one for decryption. The term cipher (sometimes cypher) is often used to refer to a pair of algorithms, one for encryption and one for decryption. Therefore, the term "cryptosystem" is most often used when the key generation algorithm is important. For this reason, the term "cryptosystem" is commonly used to refer to public key techniques; however both "cipher" and "cryptosystem" are used for symmetric key techniques.

“The novelist’s—any writer’s—object is to whittle down his meaning to the exactest and finest possible point. What, of course, is fatal is when he does not know what he does mean: he has no point to sharpen.”

“Among the most valuable but least appreciated experiences parenthood can provide are the opportunities it offers for exploring, reliving, and resolving one’s own childhood problems in the context of one’s relation to one’s child.”
