The "sslinfo" Module (v4)

Description

This module adds user facing TLS information, various TLS configuration options, and the /SSLINFO command to look up TLS certificate information for other users.

Configuration

To load this module use the following <module> tag:

<module name="sslinfo">

<connect>

This module extends the core <connect> tags with the following fields:

Name	Type	Default Value	Description
requiressl	Text	no	Whether users must be using TLS to use this class.

The requiressl field should be set to one of the following values:

Value	Description
no	TLS is not required to use this class.
trusted	TLS is required and and a CA-verified client certificate must be provided to use this class.
yes	TLS is required to use this class.

Example Usage

Requires users to be using TLS to be assigned to the Secure class:

<connect name="Secure"
         ...
         requiressl="yes">

<oper> & <type>

This module extends the core <oper> and <type> tags with the following fields:

Name	Type	Default Value	Description
fingerprint	Text	None	If defined then a space-delimited list of TLS client certificate fingerprints to check against this server operator's TLS client certificate.
sslonly	Boolean	No	Whether this server operator must be connected using TLS to log into their account.

Example Usage

Requires Sadie to connect with TLS with the TLS client certificate fingerprint 5d7499e1a3537687a2e875fed60b171508a4d1384351e276c4f961ab80729249 in order to log in to their server operator account:

<oper name="Sadie"
      ...
      fingerprint="5d7499e1a3537687a2e875fed60b171508a4d1384351e276c4f961ab80729249"
      sslonly="yes">

Requires server operators of type NetAdmin to connect with TLS with the TLS client certificate fingerprint 5d7499e1a3537687a2e875fed60b171508a4d1384351e276c4f961ab80729249 in order to log in to their server operator account:

<type name="NetAdmin"
      ...
      fingerprint="5d7499e1a3537687a2e875fed60b171508a4d1384351e276c4f961ab80729249"
      sslonly="yes">

<sslinfo>

The <sslinfo> tag defines settings about how the sethost module should behave. This tag can only be defined once.

Name	Type	Default Value	Description
hash	Text	None	The IANA Hash Function Textual Name of the hash algorithm used when getting client fingerprints sent by a WebIRC gateway.
localsecure	Boolean	Yes	Whether to consider clients connecting from localhost as secure even if they are not using TLS.
operonly	Boolean	No	Whether user TLS certificate fingerprints are only visible to server operators.
spkifp	Boolean	No	Whether to use a Subject Public Key Info (SPKI) fingerprint for WebIRC gateway clients instead of a certificate fingerprint.
warnexpiring	Duration	0s	The maximum amount of time left that can be left on a TLS client certificate before clients start being warned of the expiration time. If set to 0s then no warning will be sent.

Example Usage

<sslinfo hash="sha-256"
         localsecure="yes"
         operonly="no"
         spkifp="no"
         warnexpiring="1w">

Commands

Name	Parameter Count	Syntax	Description
SSLINFO	1	<target>	Views the TLS certificate information for <target>.

Example Usage

Views the TLS certificate information for Sadie:

/SSLINFO Sadie

Views the TLS certificate information for users in #wibble:

/SSLINFO #wibble
