Cryptosystems
 
 
Everything to do with security.
A cryptosystem is a cryptographic algorithm,
- the key or password management
 - the environment
 - the network
 - the protocol
 - the people
 - everything else
 
 
  Notes: 
  
  
In case you hadn’t guessed, the SEX was to make you pay attention.
Sometimes cryptosystems are referred to as Cryptographic Protocols, but I find this confusing and sometimes too restrictive.
