For example, on the switch, you would generate the phonetic and hexadecimal
versions of the switch's public key in figure 7-7 as follows:
Figure 7-9. Examples of Visual Phonetic and Hexadecimal Conversions of the Switch's Public Key
The two commands shown in figure 7-9 convert the displayed format of the
switch's (host) public key for easier visual comparison of the switch's public
key to a copy of the key in a client's "known host" file. The switch has only
one RSA host key. The 'babble' and 'fingerprint' options produce two hashes
for the key--one that corresponds to the challenge hash you will see if con­
necting with a v1 client, and the other corresponding to the hash you will see
if connecting with a v2 client. These hashes do not correspond to different
keys, but differ only because of the way v1 and v2 clients compute the hash
of the same RSA key. The switch always uses ASCII version (without babble
or fingerprint conversion) of its public key for file storage and default display
format.
4. Enabling SSH on the Switch and Anticipating SSH
T
parameters the switch uses for transactions with clients. After you enable
SSH, the switch can authenticate itself to SSH clients.
Non-encoded ASCII numeric string: Requires a client ability to
display the keys in the "known hosts" file in the ASCII format. This
method is tedious and error-prone due to the length of the keys. (See
figure 7-7 on page 7-14.)
Phonetic hash: Outputs the key as a relatively short series of alpha­
betic character groups. Requires a client ability to convert the key to
this format.
Hexadecimal hash: Outputs the key as a relatively short series of
hexadecimal numbers. Requires a parallel client ability.
