      Split onion.[ch] into onion{,_fast,_tap}.[ch] · f7e590df
      Nick Mathewson authored
      I'm going to want a generic "onionskin" type and set of wrappers, and
      for that, it will be helpful to isolate the different circuit creation
      handshakes.  Now the original handshake is in onion_tap.[ch], the
      CREATE_FAST handshake is in onion_fast.[ch], and onion.[ch] now
      handles the onion queue.
      
      This commit does nothing but move code and adjust header files.

      Wrangle curve25519 onion keys: generate, store, load, publish, republish · 5b3dd161
      Nick Mathewson authored
      Here we try to handle curve25519 onion keys from generating them,
      loading and storing them, publishing them in our descriptors, putting
      them in microdescriptors, and so on.
      
      This commit is untested and probably buggy like whoa

      Move curve25519 keypair type to src/common; give it functions · 6c883bc6
      Nick Mathewson authored
      This patch moves curve25519_keypair_t from src/or/onion_ntor.h to
      src/common/crypto_curve25519.h, and adds new functions to generate,
      load, and store keypairs.

      Refactor strong os-RNG into its own function · 25c05cb7
      Nick Mathewson authored
      Previously, we only used the strong OS entropy source as part of
      seeding OpenSSL's RNG.  But with curve25519, we'll have occasion to
      want to generate some keys using extremely-good entopy, as well as the
      means to do so.  So let's!
      
      This patch refactors the OS-entropy wrapper into its own
      crypto_strongest_rand() function, and makes our new
      curve25519_secret_key_generate function try it as appropriate.

      Implementat the ntor handshake · cf4dd5fb
      Nick Mathewson authored
      The ntor handshake--described in proposal 216 and in a paper by
      Goldberg, Stebila, and Ustaoglu--gets us much better performance than
      our current approach.

      Add a wrapper around, and test and build support for, curve25519. · 89ec5848
      Nick Mathewson authored
      We want to use donna-c64 when we have a GCC with support for
      64x64->uint128_t multiplying.  If not, we want to use libnacl if we
      can, unless it's giving us the unsafe "ref" implementation.  And if
      that isn't going to work, we'd like to use the
      portable-and-safe-but-slow 32-bit "donna" implementation.
      
      We might need more library searching for the correct libnacl,
      especially once the next libnacl release is out -- it's likely to have
      bunches of better curve25519 implementations.
      
      I also define a set of curve25519 wrapper functions, though it really
      shouldn't be necessary.
      
      We should eventually make the -donna*.c files get build with
      -fomit-frame-pointer, since that can make a difference.

      curve25519-donna-c64: work on bigendian and alignment-happy systems · f0696602
      Nick Mathewson authored
      There was one place in curve25519-donna-c64 that was relying on
      unaligned access and relying on little-endian values.  This patch
      fixes that.
      
      I've sent Adam a pull request.

      Add a data-invariant linear-search map structure · cfab9f07

      I'm going to use this for looking op keys server-side for ntor.

      Avoid spurious local-port warnings · ee418261
      Nick Mathewson authored
      Our old warn_nonlocal_client_ports() would give a bogus warning for
      every nonlocal port every time it parsed any ports at all.  So if it
      parsed a nonlocal socksport, it would complain that it had a nonlocal
      socksport...and then turn around and complain about the nonlocal
      socksport again, calling it a nonlocal transport or nonlocal dnsport,
      if it had any of those.
      
      Fixes bug 7836; bugfix on 0.2.3.3-alpha.
