RELIC [0] might also be worth a look, however it's more research oriented
and not yet totally optimized for performance. It recently got support for
twisted Edwards curves over prime fields (e.g. ed25519). For much longer it
supports short Weierstraß curves over prime fields and binary fields. It
also has symmetric and asymmetric pairings. However, keep in mind it's more
from an academic background and not optimized for constant time and best
performance yet.
