The 'show crypto host-public-key' displays it in two different formats because
your client may store it in either of these formats after learning the key. If you
wish to compare the switch key to the key as stored in your client's known-
hosts file, note that the formatting and comments need not match. For version
1 keys, the three numeric values bit size, exponent <e>, and modulus <n> must
match; for PEM keys, only the PEM-encoded string itself must match.
