Hi,
I've two question:
1)- how works the encryption of communication between a NAS (e.g. a router) and a TACACS+ server? the shared secret are used whit MD5, des, RC4 .... ?
2)- The authentication with MD5 uses the Hash function to create a nonces, this operation is really (mathematically) irreversible or only computationally?
