I had changed the SSH password on something so I had to dig through my known hosts file, and saw the word FUCK spelled out in there in all caps. I chuckled but am sure there's an explanation

I think I got "cunT" once and gave myself a heart attack because I thought I had accidentally committed a frustrated debugging log message to a work repo. I found it while searching for swears but it was in a file I hadn't changed

frustrated debugging log message

Just use porn actresses' names. Or so a friend told me...

We had a system at work that generated 4 character alphanumeric reference numbers. Originally to avoid this they just excluded vowels from the letters but eventually they grew enough they ran out of available reference numbers so they added the vowels back in and I had to built the blacklist to avoid stuff like this happening. I reckon I probably tripped every IT filter known to man in a week long period looking for swear words in a variety of languages 😂

That would be a rare, shiny PEM

I think you are obligated to share your entire known hosts file to prove this.

Man this feels like deep lore at this point 😂

Whaaaaat. I had no idea this had disappeared... sad news!

Thankfully it's archived at least: https://archive.is/BYZ9l

The part where people share asterisks when they talk about their passwords? Just seems like good security honestly 😂 Glad Lemmy is keeping up with this pinnacle of security best practices.

The ~/.ssh/known_hosts file only contains public keys. I mean, maybe someone doesn't want to hand out the list of hosts that they talk to, but exposing it doesn't expose the private keys, which are what you really need to keep secret.

Those are in ~/.ssh/id_rsa or the like, depending upon key type.

New blockchain just dropped

[–] InverseParallax 4 points 3 months ago

Trump's coin dropped already.

The explanation is that it's random. Generate enough random strings and you're bound to get everything.

I know that "Vanity Addresses" are a common thing for onion sites, and there are tools which generate tons of keys looking for prefixes. I haven't seen such a tool for ssh host keys though.

[–] [email protected] 2 points 3 months ago

They exist, but they're not nearly as fleshed out as the bitcoin vanity generators are. https://github.com/danielewood/vanityssh-go

not particularly exciting I think I had 'dog' one time while distro hopping.

Should've been 'bunny'.

The explanation is pretty boring. If you look at https://superuser.com/questions/421997/what-is-a-ssh-key-fingerprint-and-how-is-it-generated it's explained that some fingerprints are displayed with Base64, which according to https://en.wikipedia.org/wiki/Base64 allows the use of all 26 letters of the alphabet, and both the complete uppercase and lowercase sets.

So basically it's just random chance that a given fingerprint has some data that shows up as a word.

SSH keys can likewise use base64, e.g. for PEM format, as per https://unix.stackexchange.com/questions/492704/what-encoding-is-used-for-the-keys-when-using-ssh-keygen-t-rsa
