Jochen Hoenicke 1b42fde852 Off by one error in word length. 
This could lead to a buffer overrun if the final 0 byte is
written to current_word[j] after the loop.

Also document the limit of passphrase in mnemonic_to_seed.

trezor-crypto

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 (only hardcoded secp256k1 curve, 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)
