NAME

       dropbearconvert - convert between Dropbear and OpenSSH private key formats

SYNOPSIS

       dropbearconvert input_type output_type input_file output_file

DESCRIPTION

       Dropbear and OpenSSH SSH implementations have different private key formats.  dropbearconvert can convert
       between the two.

       Dropbear  uses the same SSH public key format as OpenSSH, it can be extracted from a private key by using
       dropbearkey -y

       Encrypted private keys are not supported, use ssh-keygen(1) to decrypt them first.

ARGUMENTS

       input_type
              Either dropbear or openssh

       output_type
              Either dropbear or openssh

       input_file
              An existing Dropbear or OpenSSH private key file

       output_file
              The path to write the converted private key file. For client authentication ~/.ssh/id_dropbear  is
              loaded by default

SUPPORTED FORMATS

       dropbearconvert  can  read  OpenSSH  format  files,  and  older  PEM  format files ( ssh-keygen -m PEM ).
       dropbearconvert will write OpenSSH format files, usable with OpenSSH  6.5  and  later.   Reading  OpenSSH
       format DSS files or PKCS8 files is not currently supported.

EXAMPLE

        # dropbearconvert openssh dropbear ~/.ssh/id_rsa ~/.ssh/id_dropbear
