TextSecure(signal) client package for Go

TextSecure library and command line test client for Go

This is a Go package implementing the TextSecure push data (i.e. not encrypted SMS) protocol v3 including the Axolotl ratchet.

The included sample command line app can send and receive text messages and attachments and supports group chat.

The API presented by the package is in flux, mainly driven by the needs of https://github.com/nanu-c/axolotl

Automatically generated documentation can be found on GoDoc

Installation

This command will install both the library and the test client.

go get github.com/signal-golang/textsecure/cmd/textsecure

textsecure also depends on crayfish which is a Go library for interacting with the upstream libsignal-client library. It's currently used for registration and decryption of messages. libzkgroup is used for the groupv2 protocol and is add by [this go wrapper] (https://github.com/nanu-c/zkgroup). It has to be added to the LD_LIBRARY_PATH environment variable. Crayfish is built with cago build and has to be placed next to the textsecure binary.

Configuration

Copy cmd/textsecure/.config to a directory and modify it, then run the tool from that directory. It will create .storage to hold all the protocol state. Removing that dir and running the tool again will trigger a reregistration with the server.

Usage

Do not run multiple instances of the app from the same directory, it (and the server) can get confused

This will show the supported command line flags

textsecure -h

Running the command without arguments will put it in receiving mode, and once it receives a message it will be able to talk to that contact.

Discussions

User and developer discussions happen on the mailing list

textsecure's Issues

Release v1.3.1 libzkgroup_linux_amd64.so needed

Just compiled the latest release from today and encountered that the library is missing on the system, which the tool wants

/usr/bin/signal: error while loading shared libraries: libzkgroup_linux_amd64.so: cannot open shared object file: No such file

and therefore don't want to start.

I just got back to Release v.1.2.14 https://github.com/signal-golang/textsecure/releases/tag/v1.2.14 and this works flawlessly and doesn't need this library.

Any Ideas?
Thanks

Go get does not work

Running the following command go get github.com/signal-golang/textsecure/cmd/textsecure I get an output of:

# github.com/signal-golang/textsecure/cmd/textsecure
go/src/github.com/signal-golang/textsecure/cmd/textsecure/main.go:139:16: not enough arguments in call to client.cmdable.Publish
        have (string, []byte)
        want (context.Context, string, interface {})

Is there another way I am supposed to be using the library?

Crayfish not working

I have built the latest version https://github.com/signal-golang/textsecure/tree/v1.4.3 and wanted to run it in gateway mode like @morph027 documented it in https://morph027.gitlab.io/signal-web-gateway/

Unfortunately the crayfish does not work.
When starting the program, following output is logged:

level=info msg="[textsecure] Checking certificate"
level=debug msg="[textsecure] GetRegisteredContacts"
level=info msg="[textsecure-crayfish] Starting crayfish-backend"
level=error msg="[textsecure-crayfish] crayfish not found"
level=debug msg="[textsecure-crayfish-ws] BackendStartListening"
level=debug msg="[textsecure-crayfish-ws] websocket connecting to crayfish-server"
level=error msg="dial tcp [::1]:9081: connect: connection refused"
level=error msg="[textsecure-crayfish-ws] Failed to start listening" error="dial tcp [::1]:9081: connect: connection refused"
level=info msg="[crayfish] /home/signal\n"
level=info msg="[textsecure-crayfish-ws] out: /home/signal\n\n"
level=info msg="[textsecure-crayfish-ws] err: \n"
level=info msg="[textsecure-crayfish] Crayfish-backend finished with error: <nil>"

therefore it also unsuccessfully tries to connect to the crayfish server:

level=debug msg="[textsecure] Websocket sending message"
level=debug msg="[textsecure-crayfish-ws] websocket connecting to crayfish-server"
level=error msg="dial tcp [::1]:9081: connect: connection refused"
level=error msg="[textsecure-crayfish-ws] Failed to start listening" error="dial tcp [::1]:9081: connect: connection refused"
level=debug msg="[textsecure-crayfish-ws] websocket connecting to crayfish-server"
level=error msg="dial tcp [::1]:9081: connect: connection refused"
level=error msg="[textsecure-crayfish-ws] Failed to start listening" error="dial tcp [::1]:9081: connect: connection refused"
level=debug msg="[textsecure-crayfish-ws] websocket connecting to crayfish-server"
level=error msg="dial tcp [::1]:9081: connect: connection refused"

Any idea what I'm missing?

The service runs just as the low privileged signal user.

Release new version

With PR #68 merged, itd be great with a new release soon as to allow axolotl to use the latest and greatest.

For more details, see nanu-c/axolotl#939 (comment)

ed25519/extra25519 change of repositories

While trying to get this project up and running, I see that https://github.com/agl/ed25519 is now deprecated and has moved to https://github.com/golang/crypto/tree/master/ed25519.

For now, I've forked the original project https://github.com/pieterbork/ed25519 and this project https://github.com/pieterbork/textsecure and changed all of the imports to build successfully. However, it seems like the correct solution is to point at the official crypto/ed25519 repo, but I'm not sure what to do about extra25519 as it is imported multiple times in textsecure and doesn't seem to be present in crypto/ed25519.

Any way to accept a group invite ?

Hi i use "signal-web-gateway" wich uses textsecure to send signal messages from check_mk.
This works fine to a single contact.

We want to send to a group which basically seems to be possible.
The problem is that i found no way to accept the group invitation with textsecure.

Is there any way or workaround to achieve this ?

Thanks in advanced!

Unable to send messages using latest build

I've just rebuild the signal commandline binary using the latest build and can't send messages.

contacts on armhf devices

Hello,

contacts are not working on armhf devices due to an issue with the 64bit conversion in a calculation. Please see this issue about details: nanu-c/axolotl#381

Solution already mentioned to change line https://github.com/signal-golang/textsecure/blob/master/contactDiscoveryCrypto/contactDiscoveryCrypto.go#L104

to
strconv.ParseInt(s, 10, 64)

nil pointer dereference when processing attachments sent by Signal Android

Signal Android clients (at least as of 4.70.3) that send a message to a client running this repo's code will trigger a nil pointer deref in handleSingleAttachment

My initial thoughts are that it is at least partially due to this Signal Android commit, as it looks like uploadAttachmentV3 is now being called where it previously may not have been: signalapp/Signal-Android@813c820

Stack trace:

textsecure gateway stops because of websocket failure

I have encountered, that the textsecure server in gateway mode stopped after some time with the error unexpected EOF because of some websocket failure. The logging level is already in debug.

I selfcompiled the binary as stated in https://morph027.gitlab.io/signal-web-gateway/installation/standalone/

From the system log:

level=debug msg="[textsecure] Received websocket pong message"
level=debug msg="[textsecure] Sending websocket ping message"
level=debug msg="[textsecure] Received websocket pong message"
level=debug msg="[textsecure] Sending websocket ping message"
level=debug msg="[textsecure] Received websocket pong message"
level=debug msg="[textsecure] Sending websocket ping message"
level=debug msg="[textsecure] Received websocket pong message"
level=error msg="websocket: close 1006 (abnormal closure): unexpected EOF"

Any Ideas?

Cheers.

428 when sending messages

textsecure has stopped sending messages and now gives error 428 on send. I am still seeing a lot of unexpected closes, but this has not been preventing textsecure to work. Sometimes the unexpected closes cause messages to not be received. I am on the latest build.

Triggering SIGSEGV by revoking Group Invite

I found a reproducible Crash in the textsecure Client

So running textsecure in Combination with a Desktop Client ist still bugging for me. For example Group Invites not working (like #43) and I can't read the messages on the Desktop Client as it only states all the time "Unterhaltungssitzung aktualisiert" on the Desktop Client.

So for the SIGSEGV Crash; How to reproduce:

1. Make Group
2. Invite Textsecure Client Number
3. Client will be invited but does not automatically accepts invitations, therefore there is an open invitation for that client
4. Revoke invitation for the invited textsecure client
5. SIGSEGV

Library doesn't work with current Signal Desktop

Looks like due to envelope timestamps, the messages from this library don't show up with Signal Desktop version 1.32.0 and above. I tested with the CLI client to confirm. I can give more information from Signal Desktop commits if needed.

textsecure.go doesn't honor logging levels set by config

If you look at textsecure.go on line 268, it sets the logging level to debug regardless of what has been set in the config file. The proper code has been commented out for unknown reasons. This causes all kinds of stuff to be in the logs, without any control over it other than manually editing the library code after pulling it down.

error when registering: Websocket message type is nil

ERRO[2022/03/18 17:58:26] [textsecure-crayfish-ws] Websocket message type is nil {"error":"missing field `request` at line 1 column 58"}

steps to reproduce:

• build latest commits of textsecure and crayfish
• ./textsecure -register
• enter phone number
• enter captcha from url in terminal output (open the signalcaptcha:// link in browser to see the captcha)
• above error message appears

Not receiving reactions

Hey,

I have an interesting issue: textsecure is receiving messages from all contacts normally, but for one contact it can't receive reactions. The log I get is:

Due to the fact that the line [textsecure] handleReceivedMessage: +00 can't even print the phonenumber, I guess something with decrypting the envelope is broken. This log appears in the switch case signalservice.Envelope_UNIDENTIFIED_SENDER in the method handleReceivedMessage(env *signalservice.Envelope) error in textsecure.go.

Can I reset something with the contact? To execute EndSession(uuid string, msg string) (uint64, error) did not help 😞

And at the same time, receiving messages from this contact works great. And sending reactions from this contact to other contacts works also.

Stops receiving after some time when running in gateway mode

After adding the listener to gateway functions (commit) my bot/listener sometimes stops listening, but is still able to send messages.

i've noticed the following messages when this happens:

Jan 09 13:19:58 signal-gateway signal[1505]: time="2020/01/09 13:19:58" level=debug msg="[textsecure] Closing writeWorker"
Jan 12 09:49:41 signal-gateway signal[2008]: time="2020/01/12 09:49:41" level=debug msg="[textsecure] Closing writeWorker"
Jan 14 05:56:24 signal-gateway signal[5517]: time="2020/01/14 05:56:24" level=debug msg="[textsecure] Closing writeWorker"

Looks like this is affecting the receiving of messages in

textsecure/websocket.go

Lines 105 to 138 in 8ed6f75

	func (c *Conn) writeWorker() {
	ticker := time.NewTicker(pingPeriod)
	defer func() {
	log.Debugf("[textsecure] Closing writeWorker")
	ticker.Stop()
	c.ws.Close()
	}()
	for {
	select {
	case message, ok := <-c.send:
	if !ok {
	log.Errorf("[textsecure] Failed to read message from channel")
	c.write(websocket.CloseMessage, []byte{})
	return
	}
	log.Debugf("[textsecure] Websocket sending message")
	if err := c.write(websocket.BinaryMessage, message); err != nil {
	log.WithFields(log.Fields{
	"error": err,
	}).Error("[textsecure] Failed to send websocket message")
	return
	}
	case <-ticker.C:
	log.Debugf("[textsecure] Sending websocket ping message")
	if err := c.write(websocket.PingMessage, nil); err != nil {
	log.WithFields(log.Fields{
	"error": err,
	}).Error("[textsecure] Failed to send websocket ping message")
	return
	}
	}
	}
	}

Should probably restart/re-open the socket handler when this happens and/or add a watchdog which supervises the websocket.

Missing / in commit c4ec2205937bdc7f86443c7d5e30baed6f06b646 causes attachments to fail

Hi, in the latest commit (c4ec220) the initial "/" are missing in the following:
ATTACHMENT_KEY_DOWNLOAD_PATH = "attachments/%s"
ATTACHMENT_ID_DOWNLOAD_PATH = "attachments/%d"
ATTACHMENT_UPLOAD_PATH = "attachments/"

These should be as follows:
ATTACHMENT_KEY_DOWNLOAD_PATH = "/attachments/%s"
ATTACHMENT_ID_DOWNLOAD_PATH = "/attachments/%d"
ATTACHMENT_UPLOAD_PATH = "/attachments/"

The initial missing "/" causes the URL to be "https://cdn2.signal.orgattachments/", which causes attachments to fail.

I have build binaries for textsecure and crayfish and modified the config.yml to poin to ip address of my selfhosted signal server. Registration via crayfish does not seem to work. Nothing happens after entering phone number, signal captcha, user name. Verification code is never requested. Am i missing anything for setup.

TextSecure is flooding the logs when internet is unreachable

Since the last version. Follow up of nanu-c/axolotl#328 on the Axolotl side.

Maybe we could use something like https://godoc.org/net#DialTimeout here: https://github.com/signal-golang/textsecure/blob/master/websocket.go#L55 to check if internet is available?
