Package: libsecp256k1-bitcoin-cash @ 0.22.1

Synopsis

Optimized C library for EC operations on curve secp256k1

Description

Optimized C library for cryptographic operations on curve secp256k1.

This library is used for consensus critical cryptographic operations on the Bitcoin Cash network.

Features:

• secp256k1 ECDSA signing/verification and key generation.

• secp256k1 Schnorr signing/verification (Bitcoin Cash Schnorr variant).

• Additive and multiplicative tweaking of secret/public keys.

• Serialization/parsing of secret keys, public keys, signatures.

• Constant time, constant memory access signing and pubkey generation.

• Derandomized ECDSA (via RFC6979 or with a caller provided function).

• Very efficient implementation.

• Suitable for embedded systems.

• Optional module for public key recovery.

• Optional module for ECDH key exchange (experimental).

• Optional module for multiset hash (experimental).
