Jochen Hoenicke f93b003cbc Extended comments, new function bn_add, a bug fix. 
Describe normalized, partly reduced and reduced numbers.
Comment which function expects which kind of input.
Removed unused bn_bitlen.
Add bn_add that does not reduce.
Bug fix in ecdsa_validate_pubkey: bn_mod before bn_is_equal.
Bug fix in hdnode_private_ckd: bn_mod after bn_addmod.

Build Status

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 + Base58 address representation
  • HMAC-SHA256 and HMAC-SHA512
  • PBKDF2
  • RIPEMD-160
  • SHA256/SHA512
  • unit tests (using Check - check.sf.net; in tests.c)
  • tests against OpenSSL (in test-openssl.c)
