sha2 = "0.10" # You need a hash function for nonce derivation

Should use?

This library and secp256kfun is experimental.

Feature flags

  • libsecp_compat to enable From implementations between rust-secp256k1 types.
  • proptest to enable secp256kfun's proptest feature.
  • adaptor to spec compliant ECDSA adaptor signatures.
  • serde to enable hex and binary serde serialization of data types.
  • bincode: for bincode v2 Encode/Decode implementations
