WebbNULL cipher suites provide no encryption. Export cipher suites are insecure when negotiated in a connection, but they can also be used against a server that prefers stronger suites (the FREAK attack). Suites with weak ciphers (typically of 40 and 56 bits) use encryption that can easily be broken.
