Vulnerability: SSL/TLS use of weak RC4(Arcfour) cipher port …

WebStream ciphers are vulnerable to attack if the same key is used twice (depth of two) or more. Say we send messages A and B of the same length, both encrypted using same key, K. The stream cipher produces a string of bits C (K) the same length as the messages. The encrypted versions of the messages then are: where xor is performed bit by bit. WebFor the integrity check, you should not use MD5, and, if possible, avoid SHA-1 as well. ... There is no DHE cipher suite which uses RC4.
