Elliptic curve crypto in python including secp256k1, alt_bn128, and bls12_381.
> **Warning**: This library contains some experimental codes that have **NOT** been audited.
[](https://github.com/ethereum/py_ecc) [](https://circleci.com/gh/ethereum/py_ecc) [](https://badge.fury.io/py/py-ecc)
## Quickstart
```sh
pip install py_ecc
```
## BLS Signatures
`py_ecc` implements the [IETF BLS draft standard v4](https://tools.ietf.org/html/draft-irtf-cfrg-bls-signature-04) as per the inter-blockchain standardization agreement. The BLS standards specify [different ciphersuites](https://tools.ietf.org/html/draft-irtf-cfrg-bls-signature-04#section-4) which each have different functionality to accommodate various use cases. The following ciphersuites are available from this library:
- `G2Basic` also known as `BLS_SIG_BLS12381G2_XMD:SHA-256_SSWU_RO_NUL_`
- `G2MessageAugmentation` also known as `BLS_SIG_BLS12381G2_XMD:SHA-256_SSWU_RO_AUG_`
- `G2ProofOfPossession` also known as `BLS_SIG_BLS12381G2_XMD:SHA-256_SSWU_RO_POP_`
### Basic Usage
```python
from py_ecc.bls import G2ProofOfPossession as bls_pop
private_key = 5566
public_key = bls_pop.SkToPk(private_key)
message = b'\xab' * 32 # The message to be signed
# Signing
signature = bls_pop.Sign(private_key, message)
# Verifying
assert bls_pop.Verify(public_key, message, signature)
```
### Aggregating Signatures
```python
private_keys = [3, 14, 159]
public_keys = [bls_pop.SkToPk(key) for key in private_keys]
signatures = [bls_pop.Sign(key, message) for key in private_keys]
# Aggregating
agg_sig = bls_pop.Aggregate(signatures)
# Verifying signatures over the same message.
# Note this is only safe if Proofs of Possession have been verified for each of the public keys beforehand.
# See the BLS standards for why this is the case.
assert bls_pop.FastAggregateVerify(public_keys, message, agg_sig)
```
### Multiple Aggregation
```python
messages = [b'\xaa' * 42, b'\xbb' * 32, b'\xcc' * 64]
signatures = [bls_pop.Sign(key, message) for key, message in zip(private_keys, messages)]
agg_sig = bls_pop.Aggregate(signatures)
# Verify aggregate signature with different messages
assert bls_pop.AggregateVerify(public_keys, messages, agg_sig)
```
## Developer Setup
If you would like to hack on py_ecc, please check out the [Ethereum Development Tactical Manual](https://github.com/ethereum/ethereum-dev-tactical-manual) for information on how we do:
- Testing
- Pull Requests
- Code Style
- Documentation
## Got bug?
Feel free to create issue under https://github.com/ethereum/py_ecc/issues
## Copyright and Licensing
Project is licensed under the MIT license.
## Release setup
To release a new version:
```sh
make release bump=$$VERSION_PART_TO_BUMP$$
```
#### How to bumpversion
The version format for this repo is `{major}.{minor}.{patch}` for stable, and
`{major}.{minor}.{patch}-{stage}.{devnum}` for unstable (`stage` can be alpha or beta).
To issue the next version in line, specify which part to bump,
like `make release bump=minor` or `make release bump=devnum`.
If you are in a beta version, `make release bump=stage` will switch to a stable.
To issue an unstable version when the current version is stable, specify the
new version explicitly, like `make release bump="--new-version 4.0.0-alpha.1 devnum"`
