Hi Joachim,

I recommend signify as an ed25519 example:

http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/signify/

Please note which files are used; from Makefile:

SRCS= signify.c
SRCS+= fe25519.c sc25519.c smult_curve25519_ref.c
SRCS+= mod_ed25519.c mod_ge25519.c
SRCS+= crypto_api.c

.PATH for these files:

http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/

I don't have access to my machine and I can only offer/send links :/

Daniel
