DecodeServerEntry extracts a server entry from the encoding used by remote server lists and Psiphon server handshake requests.

DecodeServerEntryFields extracts an encoded server entry into a ServerEntryFields type, much like DecodeServerEntry.

DecodeServerEntryList extracts server entries from the list encoding used by remote server lists and Psiphon server handshake requests.

EncodeServerEntry returns a string containing the encoding of a ServerEntry following Psiphon conventions.

EncodeServerEntryFields returns a string containing the encoding of ServerEntryFields following Psiphon conventions.

GenerateServerEntryTag creates a server entry tag value that is cryptographically derived from the IP address and web server secret in a way that is difficult to reverse the IP address value from the tag or compute the tag without having the web server secret, a 256-bit random value which is unique per server, in addition to the IP address.

GetCapability returns the server capability corresponding to the tunnel protocol.

GetTacticsCapability returns the server tactics capability corresponding to the tunnel protocol.

NewServerEntrySignatureKeyPair creates an ed25519 key pair for use in server entry signing and verification.

NewStreamingServerEntryDecoder creates a new StreamingServerEntryDecoder.

SetFrontedMeekHTTPDialPortNumber sets the FRONTED-MEEK-OSSH dial port number, which defaults to 443.

TagToDiagnosticID returns a prefix of the server entry tag that should be sufficient to uniquely identify servers in diagnostics, while also being more human readable than emitting the full tag.

NOTE: breaks the naming convention of dropping the OSSH suffix because UsesTLS is ambiguous by itself as there are other protocols which use a TLS layer, e.g.

ValidateServerEntryFields checks for malformed server entries.

Reject reason codes are returned in SSH open channel responses.

PSIPHON_API_CLIENT_VERIFICATION_REQUEST_NAME may still be used by older Android clients.

DisabledTunnelProtocols are protocols which are still integrated, but which cannot be enabled in tactics and cannot be selected by clients.

CustomTLSProfile specifies custom TLS profile.

ServerEntry represents a Psiphon server.

StreamingServerEntryDecoder performs the DecodeServerEntryList operation, loading only one server entry into memory at a time.

UTLSExtension specifies one of the several utls.TLSExtension concrete implementations.

UTLSSpec specifies a utls.ClientHelloSpec.

ConditionallyEnabledComponents defines an interface which can be queried to determine which conditionally compiled protocol components are present.

Redefined uTLS extensions.

ServerEntryFields is an alternate representation of ServerEntry which enables future compatibility when unmarshaling and persisting new server entries which may contain new, unrecognized fields not in the ServerEntry type for a particular client version.

TunnelProtocolPortLists is a map from tunnel protocol names (or "All") to a list of port number ranges.
