ECPy

ECPy (pronounced ekpy), is a pure python Elliptic Curve library providing ECDSA, EDDSA (Ed25519), ECSchnorr, Borromean signatures as well as Point operations.

Full html documentation is available here.

ECDSA sample

from ecpy.curves     import Curve,Point
from ecpy.keys       import ECPublicKey, ECPrivateKey
from ecpy.ecdsa      import ECDSA

cv   = Curve.get_curve('secp256k1')
pu_key = ECPublicKey(Point(0x65d5b8bf9ab1801c9f168d4815994ad35f1dcb6ae6c7a1a303966b677b813b00,
                       0xe6b865e529b8ecbf71cf966e900477d49ced5846d7662dd2dd11ccd55c0aff7f,
                       cv))
pv_key = ECPrivateKey(0xfb26a4e75eec75544c0f44e937dcf5ee6355c7176600b9688c667e5c283b43c5,
                  cv)


signer = ECDSA()
sig    = signer.sign(b'01234567890123456789012345678912',pv_key)
assert(signer.verify(b'01234567890123456789012345678912',sig,pu_key))

Point sample

from ecpy.curves     import Curve,Point

cv = Curve.get_curve('secp256k1')
P  = Point(0x65d5b8bf9ab1801c9f168d4815994ad35f1dcb6ae6c7a1a303966b677b813b00,
           0xe6b865e529b8ecbf71cf966e900477d49ced5846d7662dd2dd11ccd55c0aff7f,
           cv)
k  = 0xfb26a4e75eec75544c0f44e937dcf5ee6355c7176600b9688c667e5c283b43c5
Q  = k*P
R  = P+Q
