ECCoxide -- Rust Elliptic Curve Cryptography

General elliptic curve cryptography

⚠️ Disclaimer

This is not a ready-to-use in production code crate, but instead provide generic mechanism to experiment with elliptic curve cryptography.

TODO

this is a not exhaustive list:

• NonZeroFieldElement, NonZeroScalar
• Constant time Result/Either (CtResult, CtEither)
• add assign{add,sub,mul}
• add all other fiat implementation
  • generated sqrt & inverse "addition-chain"
  • macro to write addition chain
  • constantness
• scaling functions
• Scalar to FieldElement
• NonZeroScalar to NonZeroFieldElement
• audit function for CT
• init from wide binary : remove bias
  • need barrett reduction
• "hash"-to-curve (point)
• add ECDH/ECDSA
• fence bigint implementation behind a rust package flag
• special weirstrass curves : A=0, A=-3
• non weirstrass curves
