## Elliptic curve FIPS 186-3
Cloned from the ecc project
Pure Python implementation of an elliptic curve cryptosystem based on FIPS 186-3
Cloned from the ecc project
This is an adaptation from the original to Python Version 3.
Also added test suite.

### Getting Started
org2 = Random.new().read(80)
org = base64.b64encode(org2)
ttt = time.time()
k = Key.generate(256)
print("key gen time %.3fms" % ((time.time() - ttt) * 1000) )
print("org:")
print(org2)
ttt = time.time()
sss = k.encrypt(org)
print("encrypt time %.3fms" % ((time.time() - ttt) * 1000) )
ttt = time.time()
ddd = k.decrypt(sss)
print("decypt time %.3fms" % ((time.time() - ttt) * 1000) )
ddd2 = base64.b64decode(ddd)
print("dec:")
print(ddd2)
### The above command will print:
key gen time 2.669ms
org:
b'\xdb\xef\xcf\xdc\xc3\x03\x0e\xfd\x05\x9c\x8b\xba\xa8\x05\x0e\xd7\x9d(1\xb2\x80\x80t\xd05\xed\x8f\xa4\x81\xa7'
encrypt time 5.411ms
decypt time 2.803ms
dec:
b'\xdb\xef\xcf\xdc\xc3\x03\x0e\xfd\x05\x9c\x8b\xba\xa8\x05\x0e\xd7\x9d(1\xb2\x80\x80t\xd05\xed\x8f\xa4\x81\xa7'
