Adam Ierymenko	8c9b73f67b	Make Salsa20 variable-round, allowing for Salsa20/12 to be used for Packet encrypt and decrypt. Profiling analysis found that Salsa20 encrypt was accounting for a nontrivial percentage of CPU time, so it makes sense to cut this load fundamentally. There are no published attacks against Salsa20/12, and DJB believes 20 rounds to be overkill. This should be more than enough for our needs. Obviously incorporating ASM Salsa20 is among the next steps for performance.	2013-10-18 17:39:48 -04:00

Adam Ierymenko	ce14ba9004	Take the 0.6.0 opportunity to add flags to a few protocol verbs and do a bit more cleanup. Also fix it so certificates wont be accepted unless they are newer than existing ones.	2013-10-17 06:41:52 -04:00
Adam Ierymenko	7e7e28f5f7	Add support for pushing network config refresh hints from a MEMORY queue table. That ways it will be possible for network changes to take effect almost immediately across all active peers.	2013-10-17 05:37:01 -04:00

Adam Ierymenko	2fa2796f2a	Another tweak, hopefully final, to reduce variance on identity generation times.	2013-10-07 14:31:13 -04:00
Adam Ierymenko	343b7f44fc	Old algo for ID derivation was not in fact memory-hard since Salsa20 is seekable, so take two.	2013-10-07 12:48:27 -04:00
Adam Ierymenko	0c8614b9c6	Add a second arg to idtool generate to make generating both secret and public easier, add new supernode identities after generating them, fix known good and bad IDs in selftest.	2013-10-07 09:36:20 -04:00
Adam Ierymenko	5fa7a92048	Allocate genmem[] since its too big for the stack on some systems.	2013-10-06 05:28:25 -04:00
Adam Ierymenko	bc715fbd51	Make new identity hashcash algo memory hard, and tweak generation time a bit. Current hashcash cost should be overkill for what we need but still tolerable to users.	2013-10-05 14:15:59 -04:00
