Prefer stronger algorithms in algorithm negotiation.
Prefer diffie-hellman-group14-sha1 (2048 bit) over
diffie-hellman-group1-sha1 (1024 bit).
Due to meet-in-the-middle attacks the effective key length of
three key 3DES is 112 bits. AES is stronger and faster then 3DES.
Prefer to delay the start of compression until after authentication
has completed. This avoids exposing compression code to attacks
from unauthenticated users.

.TH dropbearconvert 1 .SH NAME dropbearconvert \- convert between Dropbear and OpenSSH private key formats .SH SYNOPSIS .B dropbearconvert .I input_type .I output_type .I input_file .I output_file .SH DESCRIPTION .B Dropbear and .B OpenSSH SSH implementations have different private key formats. .B dropbearconvert can convert between the two. .P Dropbear uses the same SSH public key format as OpenSSH, it can be extracted from a private key by using .B dropbearkey \-y .P Encrypted private keys are not supported, use ssh-keygen(1) to decrypt them first. .SH OPTIONS .TP .B input type Either .I dropbear or .I openssh .TP .B output type Either .I dropbear or .I openssh .TP .B input file An existing Dropbear or OpenSSH private key file .TP .B output file The path to write the converted private key file .SH EXAMPLE # dropbearconvert openssh dropbear ~/.ssh/id_rsa ~/.ssh/dropbear_priv .SH AUTHOR Matt Johnston ([email protected]). .SH SEE ALSO dropbearkey(1), ssh-keygen(1) .P https://matt.ucc.asn.au/dropbear/dropbear.html
