SYNOPSIS
dropbearkey -t type -f file [-s bits] [-y]DESCRIPTION
dropbearkey generates a RSA, DSS, or ECDSA 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 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

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
