5 [http://xmpp.org/extensions/xep-0257.html XEP-0257] specifies a protocol for clients to store and manage client side certificates. When a client presents a stored client side certificate during the TLS handshake, it can log in without supplying a password (using SASL EXTERNAL). This makes it possible to have multiple devices accessing an account, without any of them needing to know the password, and makes it easier to revoke access for a single device.

10 Each user can add their own certificates. These do not need to be signed by a trusted CA, yet they do need to be valid at the time of logging in and they should include an subjectAltName with otherName "id-on-xmppAddr" with the JID of the user.

35 # Replace the values for {{{otherName.0}}} and {{{commonName}}} and {{{emailAddress}}} with your own values. The JID in {{{otherName.0}}} can either be a full JID or a bare JID, in the former case, the client can only use the resource specified in the resource. There are many other fields you can add, however, for SASL EXTERNAL, they will have no meaning. You can add more JIDs as {{{otherName.1}}}, {{{otherName.2}}}, etc.

50 The {{{client.key}}} *must* be kept secret, and is only needed by clients connecting using this certificate. The {{{client.crt}}} file contains the certificate that should be sent to the server using XEP-0257, and is also needed by clients connecting to the server. The {{{client.req}}} file is not needed anymore.
