Consider below cipher suite TLS v1.0

TLS_RSA_WITH_DES_CBC_SHA                **DES-CBC-SHA**
TLS_RSA_WITH_3DES_EDE_CBC_SHA           **DES-CBC3-SHA**

Wwhat is the meaning of CBC and CBC3, and what is the difference between them?

DES-CBC-SHA is DES encryption, SHA-1 as HMAC.
DES-CBC3-SHA is 3DES encryption, SHA-1 as HMAC.
