Example

说明
dropbearkey generates SSH host and user keys in Dropbear's native format. Dropbear is a lightweight SSH implementation commonly used on embedded systems, routers, and resource-constrained devices where OpenSSH would be too large. The tool supports modern key types including Ed25519, ECDSA, and RSA with configurable key sizes. Generated keys are stored in Dropbear's own format, which differs from OpenSSH's format. If you need to use keys with OpenSSH or vice versa, use dropbearconvert to convert between formats. Host keys are typically stored in /etc/dropbear/, while user keys can be placed in standard SSH locations.
