Hex string following key path

[Dragos Ilie]

Hi,


Can somebody explain what is the hex string following the path to the
RSA key used for authentication? For an example, see last line in the
debug snippet shown below.

debug1: SSH2_MSG_SERVICE_REQUEST sent
debug2: service_accept: ssh-userauth
debug1: SSH2_MSG_SERVICE_ACCEPT received
debug2: key: /Users/blah/.ssh/id_rsa (0x6fef81c1d114)


How is that value generated? Is it something I can also do from the
command line? First, I thought it is the fingerprint of the public key
(as in ssh-keygen -l), but that's not it.


Regards,
Dragos
