dropbearkey
TLDR
Generate ed25519 key
$ dropbearkey -t ed25519 -f [path/to/key_file]
Generate ECDSA key$ dropbearkey -t ecdsa -f [path/to/key_file]
Generate RSA key with 4096 bits$ dropbearkey -t rsa -s 4096 -f [path/to/key_file]
Print fingerprint and public key$ dropbearkey -y -f [path/to/key_file]
SYNOPSIS
dropbearkey [options]
DESCRIPTION
dropbearkey generates SSH keys in Dropbear format. Dropbear is a lightweight SSH implementation for embedded systems.
Keys generated are not directly compatible with OpenSSH format; use dropbearconvert to convert between formats.
PARAMETERS
-t type
Key type (rsa, ecdsa, ed25519)-f file
Output key file-s bits
Key size in bits (for RSA)-y
Print public key and fingerprint from existing key
CAVEATS
Dropbear key format differs from OpenSSH. Use dropbearconvert to convert keys. Part of Dropbear SSH suite, common in embedded Linux.
