Is it completely safe to publish an ssh public key? [duplicate]
I use a RSA key to log into remote servers with ssh. And I keep my dot files under version control in a publicly accessible place so that I can quickly setup new servers to work the way I like.
Right now I don't have my .ssh directory under version control. But it would save a step if I could keep .ssh/authorized_keys in the dotfile repository.
It's just a public key. My private key sits only on trusted client machines in my possession, of course. I made it a 4096-bit RSA key because that seems like the best balance between wide compatibility with common sshd versions and security.
So my question is, is there any security problem with literally publicly publishing the public key? Nobody is regularly nosing around my dotfiles repository, but it's not a secret and anybody interested could read them.
