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
