Read-Write locking primitive
Synchronization object used in a solution of so-called second
readers-writers problem. In this problem, many readers can simultaneously
access a share, and a writer has an exclusive access to this share.
Additionally, the following constraints should be met:
1) no reader should be kept waiting if the share is currently opened for
reading unless a writer is also waiting for the share,
2) no writer should be kept waiting for the share longer than absolutely
necessary.
The implementation is based on [1, secs. 4.2.2, 4.2.6, 4.2.7]
with a modification -- adding an additional lock (C{self.__readers_queue})
-- in accordance with [2].

on the right (least significant bits, looking from big endian perspective)

"""
Low level implementation of Elliptic-Curve Digital Signatures.
.. note ::
You're most likely looking for the :py:class:`~ecdsa.keys` module.
This is a low-level implementation of the ECDSA that operates on
integers, not byte strings.
NOTE: This a low level implementation of ECDSA, for normal applications
you should be looking at the keys.py module.
Classes and methods for elliptic-curve signatures:
private keys, public keys, signatures,
and definitions of prime-modulus curves.
Example:
.. code-block:: python
# (In real-life applications, you would probably want to
# protect against defects in SystemRandom.)
from random import SystemRandom
randrange = SystemRandom().randrange
# Generate a public/private key pair using the NIST Curve P-192:
g = generator_192
n = g.order()
secret = randrange( 1, n )
pubkey = Public_key( g, g * secret )
privkey = Private_key( pubkey, secret )
# Signing a hash value:
hash = randrange( 1, n )
signature = privkey.sign( hash, randrange( 1, n ) )
# Verifying a signature for a hash value:
if pubkey.verifies( hash, signature ):
print_("Demo verification succeeded.")
else:
print_("*** Demo verification failed.")
# Verification fails if the hash value is modified:
if pubkey.verifies( hash-1, signature ):
print_("**** Demo verification failed to reject tampered hash.")
else:
print_("Demo verification correctly rejected tampered hash.")
Revision history:
2005.12.31 - Initial version.
2008.11.25 - Substantial revisions introducing new classes.
2009.05.16 - Warn against using random.randrange in real applications.
2009.05.17 - Use random.SystemRandom by default.
Originally written in 2005 by Peter Pearson and placed in the public domain,
modified as part of the python-ecdsa package.
