mod_compat_roles: New module providing compat shim for trunk's new role API
The new role API is translated to is_admin() calls on older versions. On newer
versions (which have the role API) this module does nothing.
It allows modules to drop their use of is_admin() (which is not available in
trunk) and switch to the new role API, while remaining compatible with
previous Prosody versions.

--- summary: Cipher policy enforcement with application level error reporting ... # Introduction This module arose from discussions at the XMPP Summit about enforcing better ciphers in TLS. It may seem attractive to disallow some insecure ciphers or require forward secrecy, but doing this at the TLS level would the user with an unhelpful "Encryption failed" message. This module does this enforcing at the application level, allowing better error messages. # Configuration First, download and add the module to `module_enabled`. Then you can decide on what policy you want to have. Requiring ciphers with forward secrecy is the most simple to set up. ``` lua tls_policy = "FS" -- allow only ciphers that enable forward secrecy ``` A more complicated example: ``` lua tls_policy = { c2s = { encryption = "AES"; -- Require AES (or AESGCM) encryption protocol = "TLSv1.2"; -- and TLSv1.2 bits = 128; -- and at least 128 bits (FIXME: remember what this meant) } s2s = { cipher = "AESGCM"; -- Require AESGCM ciphers protocol = "TLSv1.[12]"; -- and TLSv1.1 or 1.2 authentication = "RSA"; -- with RSA authentication }; } ``` # Compatibility Requires LuaSec 0.5
