Introduction The usage of RC4 suites ( also designated as arcfour ) for SSH are specified in [RFC4253] and [RFC4345]. [RFC4253] specifies the allocation of the "arcfour" cipher for SSH. [RFC4345] specifies and - allocates the the "arcfour-128" and "arcfour-256" ciphers for SSH. - RC4 encryption has known weaknesses [RFC7465] + allocates the "arcfour-128" and "arcfour-256" ciphers for SSH. RC4 + encryption has known weaknesses [RFC7465] [I-D.ietf-curdle-des-des-des-die-die-die], and the deprecation process should be begun for their use in Secure Shell (SSH) [RFC4253]. Accordingly, [RFC4253] is updated to note the deprecation of the RC4 ciphers and [RFC4345] is moved to Historic as all ciphers it specifies MUST NOT be used. 1.1.
