DJ Bernstein and Tanja Lange did a study on which ECC curves are safe to implement and use, found at http://safecurves.cr.yp.to/ YMMV as per the snowden releases but for now curve p25514 appears to be safe AND accessible in at least 2 cli type implementations. To be avoided at present is SECCURE-0.4 and below(no safe curves as per the bernstein document) GH -- Tentacle #99 ecc public key curve p25519(pcp 0.15) 1l0$WoM5C8z=yeZG7?$]f^Uu8.g>4rf#t^6mfW9(rr910 Governments are instituted among men, deriving their just powers from the consent of the governed, that whenever any form of government becomes destructive of these ends, it is the right of the people to alter or abolish it, and to institute new government, laying its foundation on such principles, and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness.’ https://github.com/TLINDEN/pcp.git to get pcp(curve25519 cli)
