My key is 3072-bit RSA, and signed with SHA256. ... To avoid typing them, copy the id_dsa.pub, id_ecdsa.pub, id_ed25519.pub or id_rsa.pub file and edit it. * Rebuild Dropbear to provide support for Ed25519 keys. The format of this file is described in the sshd(8) manual page. In OpenSSH, authorized keys are configured separately for each user, typically in a file called authorized_keys.

You can add the contents of your id_rsa.pub file to the end of the authorized_keys file, creating it if necessary, using this command: echo public_key_string >> ~/.ssh/authorized_keys Everything works as far as using the ed25519 keys (when connecting using the new key the server provided an ed25519 … They work in pairs: we always have a public and a private key. ~/.ssh/authorized_keys Lists the public keys (DSA, ECDSA, Ed25519, RSA) that can be used for logging in as this user. The PuTTY keygen tool offers several other algorithms – DSA, ECDSA, Ed25519, and SSH-1 (RSA).. Reference Resource types. SSH keys are generated in a public/private keypair. In the PuTTY Key Generator window, click Generate. Each server and each client has its own keypair. No spaces are permitted, except within double quotes.
