Struct libssh_rs::SshKey

pub struct SshKey { /* private fields */ }

Represents the public key provided by the remote host

Implementations

impl SshKey

pub fn get_public_key_hash( &self, hash_type: PublicKeyHashType ) -> SshResult<Vec<u8>>

Returns the public key hash in the requested format. The hash is returned as binary bytes. Consider using get_public_key_hash_hexa to return it in a more human readable format.

pub fn get_public_key_hash_hexa( &self, hash_type: PublicKeyHashType ) -> SshResult<String>

Returns the public key hash in a human readable form
