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 or DSS 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 or dss.

       -f file
              Write the secret key to the file file.

       -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
