Question

In the User Authentication Protocol, when the client requests for authentication, then the first byte ( in this format) has decimal value –

(a) 80

(b) 60

(c) 50

(d) 61

The question was asked during an online exam.

My enquiry is from Secure Shell(SSH) topic in chapter Internet Protocol, Network Addressing and Transport Level Security of Cryptograph & Network Security

Answer 1

Right option is (c) 50

For explanation I would say: The first byte is assigned a value 50. This is the SSH user authentication message/byte.
