-NB: This code is not safe for use with secret keys or secret data.
-The only safe use of this code is for verifying signatures on public messages.

-Functions for computing the public key of a secret key and for signing
-a message are included, namely publickey_unsafe and signature_unsafe,
-for testing purposes only.
-
-The root of the problem is that Python's long-integer arithmetic is
-not designed for use in cryptography.  Specifically, it may take more
-or less time to execute an operation depending on the values of the
-inputs, and its memory access patterns may also depend on the inputs.
-This opens it to timing and cache side-channel attacks which can
-disclose data to an attacker.  We rely on Python's long-integer
-arithmetic, so we cannot handle secrets without risking their disclosure.

-# Implementation of elliptic curves, for cryptographic applications.
-#
-# This module doesn't provide any way to choose a random elliptic
-# curve, nor to verify that an elliptic curve was chosen randomly,
-# because one can simply use NIST's standard curves.
-#
-# Notes from X9.62-1998 (draft):
-#   Nomenclature:
-#     - Q is a public key.
-#     The "Elliptic Curve Domain Parameters" include:
-#     - q is the "field size", which in our case equals p.
-#     - p is a big prime.
-#     - G is a point of prime order (5.1.1.1).
-#     - n is the order of G (5.1.1.1).
-#   Public-key validation (5.2.2):
-#     - Verify that Q is not the point at infinity.
-#     - Verify that X_Q and Y_Q are in [0,p-1].
-#     - Verify that Q is on the curve.
-#     - Verify that nQ is the point at infinity.
-#   Signature generation (5.3):
-#     - Pick random k from [1,n-1].
-#   Signature checking (5.4.2):
-#     - Verify that r and s are in [1,n-1].
-#
-# Version of 2008.11.25.
-#
-# Revision history:
-#    2005.12.31 - Initial version.
-#    2008.11.25 - Change CurveFp.is_on to contains_point.
-#
-# Written in 2005 by Peter Pearson and placed in the public domain.
