Add a vendored copy of the secp256k1lab library (master branch, commit a265da139aea27386085a2a8760f8698e1bda64e) that the half-aggregation reference implementation and test vector scripts depend on.
secp256k1lab
An INSECURE implementation of the secp256k1 elliptic curve and related cryptographic schemes written in Python, intended for prototyping, experimentation and education.
Features:
- Low-level secp256k1 field and group arithmetic.
- Schnorr signing/verification and key generation according to BIP-340.
- ECDH key exchange.
WARNING: The code in this library is slow and trivially vulnerable to side channel attacks.
