Delivery of Cisco cryptographic products does not imply third-party authority to import, export, distribute or use encryption. Below are some of the Message Authentication Code (MAC) algorithms: hmac-md5 hmac-md5-96 hmac-sha1-96. There's also a new optinal encryption algorithm aes-gcm-128, but for now this is only selected as fallback and aes-ccm-128 is preferred because of the better performance. I’ve noticed arcfour to perform the best, but there have been legitimate complaints in the cryptography community about whether or not it is “secure. The “-c” option allows selection of cipher for a connection. 04에서도 떴었는데 당시에는 크게 신경도 안썼고 버그라는 소문도 들은듯합니다. Several ciphers are disabled by default in ssh: blowfish-cbc, cast128-cbc, all arcfour variants and the rijndael-cbc aliases for AES.
