XMPP Server List

Build Status

Public XMPP server list and metadata in JSON format. This list only includes servers with 'A' grade on xmpp.net and that allow In-Band Registration (XEP-0077).

Example:

{
  "servers": [
    {
      "name": "Calyx Institute",
      "description": "Non-profit education and research organization focused on privacy technology.",
      "website": "https://www.calyxinstitute.org",
      "twitter": "https://twitter.com/calyxinstitute", // optional
      "privacy_policy": "https://www.calyxinstitute.org/legal/privacy-policy",
      "logo": "images/calyx.jpg", // can be relative path or absolute URL to an image
      "country_code": "NL",
      "domain": "jabber.calyxinstitute.org", // domain at the end of user JIDs. For example, example.com would be the domain for [email protected]
      "server": "jabber.calyxinstitute.org", // result of DNS SRV lookup, and may be different than domain. This is required for Tor to work for domains without .onions, whose XMPP server is at a different address via SRV lookup. e.g. domain=example.com vs server=xmpp.example.com
      "onion": "ijeeynrc6x2uy5ob.onion", // optional
      "port": 5222,
      "extensions": ["XEP-0357", "XEP-0363"], // Array of some important XEPs. Unfortunately Calyx doesn't actually support these yet. 
      "requires_otr": true, // indicates if server rejects non-OTR messages
      "captcha": false, // if server requires captcha for in-band registration
      "certificate": "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"

Domain and Server

Some servers have a domain of example.com and a server of xmpp.example.com. Server should be the result of SRV lookup, you can retrieve it with dig: dig _xmpp-client._tcp.example.com SRV.

This is here mainly to make it possible for users to connect via Tor to servers without .onions, because SRV lookups are not possible over Tor.

Logos

Logos should have a 1:1 aspect ratio.

Extensions

You only need to include info about XEP-0357 and XEP-0363. You can omit other extensions, these are the only two required for clients to work properly.

Certificates

For the certificate key we need the certificate in 'der' format, converted to base64 with no linebreaks.

You can get the certificate in PEM format from the result on xmpp.net, which needs to be converted:

$ openssl x509 -outform der -in certificate.pem | openssl enc -base64 -A -out certificate.cer.base64

Or you can get it directly from the XMPP server:

$ openssl s_client -starttls xmpp -showcerts -connect example.com:5222 < /dev/null 2>/dev/null | openssl x509 -outform der | openssl enc -base64 -A -out certificate.cer.base64

Option -starttls xmpp should only be used for servers using STARTTLS. When in doubt try with and without it.
