Python wrapper around lib25519 library, wrapper around X25519 and Ed25519 cryptosystems.
Import library:
from lib25519 import x25519
Key generation:
alicepk, alicesk = x25519.keypair()
bobpk, bobsk = x25519.keypair()
Shared-secret generation:
bobk = x25519.dh(alicepk, bobsk)
alicek = x25519.dh(bobpk, alicesk)
Check:
assert alicek == bobk
Import library:
from lib25519 import ed25519
Key generation:
alicepk, alicesk = ed25519.keypair()
Signature generation:
m = b'Hello'
sm = ed25519.sign(m, alicesk)
Signature verification and message recovery:
recoveredm = ed25519.open(sm, alicepk)
Check:
assert m == recoveredm
