2015-01-09ec25519-fhmqvc: optimize handshake by using embedded group element verificationMatthias Schiffer
Using the embedded group element verification allows us to get away without explicit verification, thus needing one scalar multiplication less. This reduces the number of expensive operations needed for a handshake to three: one Galois field square root (for key unpacking) and two scalar multiplications. For this optimization to be secure, private keys must be divisible by 8. This is the case for all keys generated with all but extremely old versions of fastd (pre-0.4). If fastd finds that its secret is not divisible by 8, it will refuse to start now.
2014-08-24Use simple int64_t timestamps in ms instead of timespecsMatthias Schiffer
2014-08-02Introduce and use alloc helpersMatthias Schiffer
These new helpers will terminate fastd on allocation failures and add some additional convenience (allow strdup with NULL; typesafe new(type) macros).

2013-10-31ec25519-fhmqvc: don't use separate keypairs as initiator and responderMatthias Schiffer
This reverts commit 81a329682b2035dc56f7c6c21815bac590f34b52. As many handshake parameters depend on the handshake direction, crossed handshakes will generate completely different keys anyways.
