-Example: DH, ECDH, DHE, ECDHE, RSA
+Example: \texttt{DHE}
 
 \item{Authentication:}
 The client authenticates the server by its certificate. Optionally the server 
 may authenticate the client certificate.
 
-Example: RSA, ECDSA, DSA
+Example: \texttt{RSA}
 
 \item{Cipher:}
 The cipher is used to encrypt the message stream. It also contains the key size
 and mode used by the suite.
 
-Example: AES128, AES128\_GCM, Camellia128
+Example: \texttt{AES256}
 
 \item{Message authentication code (MAC):}
 A MAC ensures that the message has not been tampered with (integrity).
