Issues

• Design issue: In my design, the Certificate struct has an ptr to a GnuTLS certificate structure to hold its internal data. This has the consequence that the SSL connection system and X.509 handling must both be provided by GnuTLS; if, say, SILC provides the X.509 handling, and GnuTLS the SSL connections, everything grinds to a gruesome segfaulty halt.

Should I address this? The only workaround I can think of is to keep a pointer to the PEM-formatted certificate in the Certificate struct instead, but that will require any consumers of the Certificate to have PEM encoding/decoding and constantly decode it from PEM for every use. (June 19)

• How to ensure that VerificationRequests? get properly trashed in unusual conditions (such as canceling an SSL connection)? (June 26)

Resolved Issues

• It looks like PKCS12 (the certificate import/export format) is supported by both libNSS and GnuTLS.
• Jabber "connect with fd" problem solved by porting a change from soc.2007.xmpp (29 May, June 26)
• Why doesn't a "not accepted" on a certificate cause the connection to fail? (26 June)

TODO

• General paranoia
• Look at how the SILC prpl does its key management, especially the organization of the API used to check certs and interact with the user to verify them.
• Add some way of passing useful error messages back up out of the SSL interface (23 May)
• Fix purple_ssl_init in sslconn.c; it doesn't do anything (23 May)
  • Talking to nosnilmot suggests that this ought to just be removed outright (24 May)
• Figure out libNSS everything. (25 May)
• Why am I getting single-byte serial numbers from servers? (25 May)
• Work out how to use Glib functions for time checking on certificates. (29 May)
• Stall the timeouts on the TCP connection while waiting for user input on SSL? (29 May)
• Worry about ensuring that plugins don't kill in-use ciphers/certschemes when unloaded? (29 May)
• GnuTLS and NSS should probably be configured to use g_malloc and g_free for paranoia's sake (1 June)
• e408398aae606a1aafb857413db4fa9736e374ae should be disapproved. It is hacky and stupid (26 June)

Tasks done

• Figure out how to get key fingerprints out of GnuTLS (25 May, 25 May))
