TLS/SSL protocols support a large number of cipher suites. A cipher suite is a collection of symmetric and asymmetric encryption algorithms used by hosts to establish a secure communication. Supported cipher suites can be classified based on encryption algorithm strength, key length, key exchange and authentication mechanisms. Some cipher suites offer better level of security than others (e.g. Several weak cipher suites were developed for export to comply with US export law). There are more than 200 known cipher suites.
