cipher_get_keycontext() and cipher_set_keycontext() copying OpenSSL RC4 cryptographic state
These two functions in cipher.c (I have looked at openssh5.8p1 & openssh5.9p1) copy the internal cryptographic state of an OpenSSL RC4 encryption/decryption context using simple memcpy().
This code also copies the state when evptype is EVP_acss, which I am unfamiliar with.
This code appears to works fine when using the builtin crypto of OpenSSL 1.0.0d.
However, I have been doing some work
