They can be regenerated at any time. Furthermore, embedded devices often run on low-end processors that may not have a hardware random number generator. The rules for good passwords also apply here: mix of upper and lower case, numbers, spaces and punctuation. It also comes with the Git Bash tool, which is the preferred way of running git commands on Windows. Practically all cybersecurity require managing who can access what.

You will need to enter the passphrase a second time to continue. Thus, they must be managed somewhat analogously to user names and passwords. Then boot the system, collect some more randomness during the boot, mix in the saved randomness from the seed file, and only then generate the host keys. Within some of the commands found in this tutorial, you will notice some highlighted values. The key fingerprint is: 3c:fb:bf:4b:71:13:dd:d5:36:0d:94:6a:c7:23:97:75 yourusername yourmacname. The ssh-keygen utility prompts you for a passphrase. The key fingerprint is: ae:89:72:0b:85:da:5a:f4:7c:1f:c2:43:fd:c6:44:30 myname mymac.
