SSL/TLS: "Invariance Weakness" vulnerability in RC4 stream cipher

The RC4 algorithm, as used in the TLS protocol and SSL protocol, does not properly combine state data with key data during the initialization phase, which makes it easier for remote attackers to conduct plaintext-recovery attacks against the initial bytes of a stream by sniffing network traffic...

Weak SSL RC4 Cipher Suites (CVE-2013-2566; CVE-2015-2808)

RC4 is a widely supported stream cipher, often preferred by TLS servers and other servers using encrypted sessions. It has long been known to have a variety of cryptographic weaknesses. Recent cryptanalysis results, one of which is the "Bar Mitzvah attack", exploit biases in the RC4 keystream to...
