!!! Overview
In cryptography, [{$pagename}] (Rivest Cipher 4 also known as ARC4 or ARCFOUR meaning Alleged [{$pagename}], see below) is the most widely used software stream [Cipher] and is used in popular Internet protocols such as Transport Layer Security [TLS].
While remarkable for its simplicity and speed in software, [{$pagename}] has been termed [Cryptographically Weak] that and some argue against its use in new systems.
[RFC 7465] ([Prohibiting RC4 Cipher Suites]) declares [{$pagename}] as being [PROHIBITED][{$pagename}] is especially vulnerable when the beginning of the output keystream is not discarded, or when nonrandom or related keys are used; some ways of using [{$pagename}] can lead to very insecure protocols such as WEP.
As of 2015, there is speculation that some state Cryptologic agencies may possess the capability to break [{$pagename}] even when used in the TLS protocol.
Mozilla and Microsoft recommend disabling [{$pagename}] where possible.
[RFC 7465] prohibits the use of [{$pagename}] in [TLS].
