from nem_ed25519.key import secret_key, public_key, get_address
# secret key
sk = secret_key()
# public key
pk = public_key(sk)
# compressed key
ck = get_address(pk, main_net=True)
 
from nem_ed25519.signature import sign, verify
# sign message
sign = sign(msg=b'hello world', sk=sk, pk=pk)
# verify message
verify(msg=b'hello world', sign=sign, pk=pk)
 
from nem_ed25519.encrypt import encrypt, decrypt
# encrypt/decrypt message
sk1 = secret_key()
pk1 = public_key(sk1)
enc = encrypt(sk=sk, pk=pk1, msg=b'Hot potato.')
dec = decrypt(sk=sk1, pk=pk, enc=enc)
