Fabien 9ef26c347e Add support for Schnorr crypto (BCH variant) 
Support Schnorr signature and verification defined in
https://github.com/bitcoincashorg/bitcoincash.org/blob/master/spec/2019-05-15-schnorr.md.

The implementation is based on https://github.com/Bitcoin-ABC/secp256k1
as well as the test vectors.

Build Status gitter

Heavily optimized cryptography algorithms for embedded devices.

These include:

  • AES/Rijndael encryption/decryption
  • Big Number (256 bit) Arithmetics
  • BIP32 Hierarchical Deterministic Wallets
  • BIP39 Mnemonic code
  • ECDSA signing/verifying (supports secp256k1 and nist256p1 curves, uses RFC6979 for deterministic signatures)
  • ECDSA public key derivation
  • Schnorr (BCH variant) signing/verifying
  • Base32 (RFC4648 and custom alphabets)
  • Base58 address representation
  • Ed25519 signing/verifying (also SHA3 and Keccak variants)
  • ECDH using secp256k1, nist256p1 and Curve25519
  • HMAC-SHA256 and HMAC-SHA512
  • PBKDF2
  • RIPEMD-160
  • SHA1
  • SHA2-256/SHA2-512
  • SHA3/Keccak
  • BLAKE2s/BLAKE2b
  • Chacha20-Poly1305
  • unit tests (using Check - check.sf.net; in test_check.c)
  • tests against OpenSSL (in test_openssl.c)
  • integrated Wycheproof tests
