Pairings can be used for all kinds of advanced cryptographic schemes such as Encryption (Identity-based, Attribute-based, Predicate-based, etc.), Signatures, Zero-Knowledge Proofs, etc. It is in no particular order.
Provides multiple types of Elliptic Curve groups with appropriate pairings on top of them. Code repository resides here.

| A pure Python "ping" implementation, based on a rewrite by Johannes Meyer, | |
| of a script originally by Matthew Dixon Cowles. Which in turn was derived | |
| from "ping.c", distributed in Linux's netkit. The version this was forked | |
| out of can be found here: https://gist.github.com/pklaus/856268 | |
| I've rewritten nearly everything for enhanced performance and readability, | |
| and removed unnecessary functions (assynchroneous PingQuery and related). |

| To install, just copy it to your profile/startup directory, typically: | |
| ~/.ipython/profile_default/startup/ | |
| Example usage: | |
| %clip hello world | |
| # will store "hello world" |

| # This is a sample matplotlib configuration file - you can find a copy | |
| # of it on your system in | |
| # site-packages/matplotlib/mpl-data/matplotlibrc. If you edit it | |
| # there, please note that it will be overwritten in your next install. | |
| # If you want to keep a permanent local copy that will not be | |
| # overwritten, place it in HOME/.matplotlib/matplotlibrc (unix/linux | |
| # like systems) and C:\Documents and Settings\yourname\.matplotlib | |
| # (win32 systems). |
