| This Python version of the library is ideal for beginners, or for people |
| interested in quickly putting together a "proof of concept" implementation |
| that requires Elliptic curve or pairing based cryptography. |
| |
| Note this Python version is NOT for serious production use. Since the |
| handling of big numbers is outside of our control, side-channel attacks |
| cannot be prevented, so we have not even attempted to make this version |
| side-channel secure. Also since Python will never be fast, no extreme attempts |
| at optimization have been made, and some optimizations which result in larger |
| code size have been omitted. Once the Proof of Concept has been established, |
| the programmer should switch to one of the other supported languages. |
| |
| Some limitations: RSA is not currently supported. Also larger pairing-friendly |
| curves like BLS24 and BLS48 are not supported. The curves files are not |
| currently automatically generated by the romgen utility. |
| |
| Curve parameters are provided in individual files like ed25519.py and |
| bn254.py. It is a simple matter to support more curves. |
| |
| This Python version is very small, accessible, and easy to use. |
| |
| -------------------------------------- |
| |
| To see it in action, copy all of the files in this directory to a fresh directory. |
| Then execute the python3 script config.py and select the curves that you wish |
| to support. (On Linux use python3 instead of py). |
| |
| py config.py |
| |
| Select options 1 and 8, which are fixed for the example program. Select 0 |
| to exit. |
| |
| Then run the test program |
| |
| py test.py |
| |
| or |
| |
| python3 test.py |
| |
| Elliptic curve key exchange, signature and encryption (ECDH, ECDSA and ECCSI) will be tested. |
| Also MPIN and BLS (Boneh-Lynn-Shacham) signature (using pairings) |
| |
