Here you go!

~ $ cat ~/.ssh/id_rsa
cat: /data/data/com.termux/files/home/.ssh/id_rsa: No such file or directory
~ $ cat ~/.ssh/id_ed25519
cat: /data/data/com.termux/files/home/.ssh/id_ed25519: No such file or directory

The first command works for me on Termux, but the second matches your output. Does this just mean you have not set up SSH?

[-] rikudou@lemmings.world 18 points 1 month ago

I use ssh regularly, I just use a different key for each server. And thus I don't use the default name (id_rsa) because it doesn't make sense.

Let's see the hackers figure that one out!

Damn okay well if the hackers are at that level I guess you're just screwed.

[-] kionite231@lemmy.ca 4 points 1 month ago

No that means they haven't ran ssh-keygen yet

[-] idunnololz@lemmy.world 5 points 1 month ago

Or they did not use the default name. Devious D:

[-] dan@upvote.au 21 points 1 month ago

id_rsa shouldn't exist any more.

If I had a nickel for every time I had to change my ssh key algorithm I'd have two nickels.

Which isn't much but it's concerning that it happened twice.

A few days ago I was messing with my ubiquiti dream router and its ssh config option said the key should start with ssh-rsa ๐Ÿ™„

[-] dan@upvote.au 19 points 1 month ago

It probably accepts other key types and it's just the UI that's outdated. I doubt they're using an SSH implementation other than Dropbear or OpenSSH, and both support ed25519.

[-] dbx12@programming.dev 2 points 1 month ago

Could be stupid input validation which requires ^ssh-rsa

[-] Scoopta@programming.dev 11 points 1 month ago

Fact of the matter is RSA is perfectly secure still...and ECDSA/ED25519 should also be extinct given the rising need for post quantum cryptography

[-] Supermariofan67@programming.dev 16 points 1 month ago

The problem is not the RSA math itself but that it is both extremely slow and implementing it is particularly susceptible to bugs and side channel attacks https://blog.trailofbits.com/2019/07/08/fuck-rsa/

[-] Scoopta@programming.dev 1 points 1 month ago

Most of the situations I encounter RSA are in projects where I hope RSA is implemented correctly. I have a lot of Let's Encrypt certs that are still RSA and my main SSH keys are still RSA. All of these were generated quite some time ago. I understand the problem with projects that implement it incorrectly but I'd hope OpenSSH and certbot aren't those projects ๐Ÿ˜ฅ

[-] computergeek125@lemmy.world 1 points 1 month ago

For Certbot, I think it's even further up the chain - OpenSSL. And if you're installing it to Apache or Nginx, its probably just OpenSSL again.

[-] peeteer@feddit.org 2 points 1 month ago

Azure DevOps only allows you to use RSA keys. This caused a major outage in May (they switched from V1 to V2) :).

[-] blackstrat@lemmy.fwgx.uk 12 points 1 month ago

None of them...

ssh-keygen -t ecdsa -b 384

Then get it signed and use the certificate.

[-] blackstrat@lemmy.fwgx.uk 4 points 1 month ago

SSH certificates are where its at.

cat ~/.ssh/id[TAB]

[-] dosuser123456 1 points 1 month ago* (last edited 1 month ago)

i havent even configured my ssh

~ $ cat ~/.ssh/id_rsa
cat: /home/dos/.ssh/id_rsa: No such file or directory
~ $ cat ~/.ssh/id_ed25519
cat: /home/dos/.ssh/id_ed25519: No such file or directory

(i jut realized i gorgot rthis part)
