## 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'

## Errata:

  Ported from Python 2 ... Not all is carried over. This port is not 8 bit clean
but can be used with a help of hexify utils like base64.
