GetTokenFromHOTPMockFile opens HOTPMock from file, gets token value, increases hotp and saves it to the file.

NewClient creates a TeleportClient object and fully configures it.

NewFSLocalKeyStore creates a new filesystem-based local keystore object and initializes it.

NewLocalAgent loads all the saved teleport certificates and creates ssh agent with them.

ParseLabelSpec parses a string like 'name=value,"long name"="quoted value"` into a map like { "name" -> "value", "long name" -> "quoted value" }.

Username returns the current user's username.

Config is a client config.

ForwardedPort specifies local tunnel to remote destination managed by the client, is equivalent of ssh -L src:host:dst command.

FSLocalKeyStore implements LocalKeyStore interface using the filesystem Here's the file layout for the FS store: ~/.tsh/ ├── known_hosts --> trusted certificate authorities (their keys) in a format similar to known_hosts └── sessions --> server-signed session keys └── host-a | ├── cert | ├── key | └── pub └── host-b ├── cert ├── key └── pub.

HOTPMock is a HOTP that can be saved or load from file Using HOTPMock disables the hotp security level, don't use it in production.

Key describes a complete (signed) client key.

NodeClient implements ssh client to a ssh node (teleport or any regular ssh node) NodeClient can run shell and commands or upload and download files.

ProxyClient implements ssh client to a teleport proxy It can provide list of nodes or connect to nodes.

TeleportClient is a wrapper around SSH client with teleport specific workflow built in.

LocalKeyStore interface allows for different storage back-ends for TSH to load/save its keys.

HostKeyCallback is called by SSH client when it needs to check remote host key or certificate validity.
