NAME

       dropbearkey - create private keys for the use with dropbear(8) or dbclient(1)

SYNOPSIS

       dropbearkey -t type -f file [-s bits] [-y]

DESCRIPTION

       dropbearkey  generates  a RSA, DSS, ECDSA, or Ed25519 format SSH private key, and saves it
       to a file  for  the  use  with  the  Dropbear  client  or  server.   Note  that  some  SSH
       implementations use the term "DSA" rather than "DSS", they mean the same thing.

OPTIONS

       -t type
              Type of key to generate.  Must be one of rsa ecdsa ed25519 or dss.

       -f file
              Write the secret key to the file file. For client authentication ~/.ssh/id_dropbear
              is loaded by default

       -s bits
              Set the key size to bits bits, should be multiple of 8 (optional).

       -y     Just print the publickey and fingerprint for the private key in file.

NOTES

       The program dropbearconvert(1) can be used to convert between  Dropbear  and  OpenSSH  key
       formats.

       Dropbear does not support encrypted keys.

EXAMPLE

       generate a host-key:
        # dropbearkey -t rsa -f /etc/dropbear/dropbear_rsa_host_key

       extract a public key suitable for authorized_keys from private key:
        # dropbearkey -y -f id_rsa | grep "^ssh-rsa " >> authorized_keys
