1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	51 The following is a list of the pending tasks which would have to be done
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	52 to make mod\_openid fully featured. They are generally ranked in order
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	53 of most importance with an estimated degree of difficulty.

1885 b42eb10dc7d2 mod_openid/README: Convert raw HTML to emphasis Kim Alvefur <zash@zash.se> parents: 1803 diff changeset	55 1. Support Prosody 0.6.x series (Medium)
b42eb10dc7d2 mod_openid/README: Convert raw HTML to emphasis Kim Alvefur <zash@zash.se> parents: 1803 diff changeset	56 2. Refactor code (Medium)
1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	57 - The code is pretty messy at the moment, it should be refactored
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	58 to be more easily understood.

1885 b42eb10dc7d2 mod_openid/README: Convert raw HTML to emphasis Kim Alvefur <zash@zash.se> parents: 1803 diff changeset	60 3. Disable use of "user@domain" OpenID identifier form (Easy)
1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	61 - This is a vestigial feature from the early design, allowing
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	62 explicit specification of the JID. However the JID can be
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	63 inferred from the simpler OpenID identifier form.

1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	65 4. Use a cryptographically secure Pseudo Random Number Generator (PRNG)
1885 b42eb10dc7d2 mod_openid/README: Convert raw HTML to emphasis Kim Alvefur <zash@zash.se> parents: 1803 diff changeset	66 (Medium)
1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	67 - This would likely be accomplished using luacrypto which provides
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	68 a Lua binding to the OpenSSL PRNG.
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	69
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	70 5. Make sure OpenID key-value pairs get signed in the right order
1885 b42eb10dc7d2 mod_openid/README: Convert raw HTML to emphasis Kim Alvefur <zash@zash.se> parents: 1803 diff changeset	71 (*Hard*)
1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	72 - It is important that the OpenID key-value responses be signed in
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	73 the proper order so that the signature can be properly verified
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	74 by the receiving party. This may be complicated by the fact that
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	75 the iterative ordering of keys in a Lua table is not guaranteed
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	76 for non-integer keys.
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	77
1885 b42eb10dc7d2 mod_openid/README: Convert raw HTML to emphasis Kim Alvefur <zash@zash.se> parents: 1803 diff changeset	78 6. Do an actual match on the OpenID realm (Medium)
1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	79 - The code currently always returns true for matches against an
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	80 OpenID realm, posing a security risk.
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	81
1885 b42eb10dc7d2 mod_openid/README: Convert raw HTML to emphasis Kim Alvefur <zash@zash.se> parents: 1803 diff changeset	82 7. Don't use plain text authentication over HTTP (*Hard*)
1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	83 - This would require some Javascript to perform a digest.

1885 b42eb10dc7d2 mod_openid/README: Convert raw HTML to emphasis Kim Alvefur <zash@zash.se> parents: 1803 diff changeset	85 8. Return meaningful error responses (Medium)
1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	86 - Most error responses are an HTTP 404 File Not Found, obviously
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	87 something more meaningful could be returned.
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	88
1885 b42eb10dc7d2 mod_openid/README: Convert raw HTML to emphasis Kim Alvefur <zash@zash.se> parents: 1803 diff changeset	89 9. Enable Association (*Hard*)
1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	90 - Association is a feature of the OpenID specification which
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	91 reduces the number of round-trips needed to perform
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	92 authentication.
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	93
1885 b42eb10dc7d2 mod_openid/README: Convert raw HTML to emphasis Kim Alvefur <zash@zash.se> parents: 1803 diff changeset	94 10. Support HTTPS (Medium)

1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	98 - mod\_openid is designed from the OpenID 2.0 specification, which

1885 b42eb10dc7d2 mod_openid/README: Convert raw HTML to emphasis Kim Alvefur <zash@zash.se> parents: 1803 diff changeset	101 12. Check specification compliance (Medium)
1803 4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	102 - Walk through the code and make sure it complies with the OpenID
4d73a1a6ba68 Convert all wiki pages to Markdown Kim Alvefur <zash@zash.se> parents: 1782 diff changeset	103 specification. Comment code as necessary with the relevant
