Functions ¶
func HashHostname ¶
HashHostname hashes the given hostname. The hostname is not normalized before hashing.
func New ¶
New creates a host key callback from the given OpenSSH host key files. The returned callback is for use in ssh.ClientConfig.HostKeyCallback. By preference, the key check operates on the hostname if available, i.e. if a server changes its IP address, the host key check will still succeed, even though a record of the new IP address is not available.
Types ¶
type KeyError ¶
type KeyError struct { // Want holds the accepted host keys. For each key algorithm, // there can be one hostkey. If Want is empty, the host is // unknown. If Want is non-empty, there was a mismatch, which // can signify a MITM attack. Want []KnownKey }
KeyError is returned if we did not find the key in the host key database, or there was a mismatch. Typically, in batch applications, this should be interpreted as failure. Interactive applications can offer an interactive prompt to the user.
type RevokedError ¶
type RevokedError struct {
Revoked KnownKey
}
RevokedError is returned if we found a key that was revoked.
func (*RevokedError) Error ¶
func (r *RevokedError) Error() string
