Crypto demo

This repository contains Go example implementations related to several cryptographic constructs used in various DLTs.

Packages

It contains the following general packages:

  • slip10 implements the SLIP-10 private key derivation with full BIP-32 compatibility.
  • bip32path provides utilities for BIP-32 chains.
  • bip39 implements the BIP-39 specification and mnemonic word lists.
  • bech32 implements Bech32 addresses based on the format described in BIP-173.
  • ed25519 implements Ed25519 signatures with particular validation rules around edge cases as described in ZIP-215.
  • curl implements the Curl ternary hash function in its batched mode. It relies on avo to generate high-performance x86 assembly.
  • merkle implements a simple Merkle tree hash.
  • pow implements the Curl-based proof of work for arbitrary binary data as mentioned in TIP-12.
  • encoding/b1t6 implements the binary-to-ternary encoding which uses 6 trits to represent each byte.
  • encoding/b1t8 implements the binary-to-ternary encoding which uses 8 trits to represent each byte.
  • migration implements the migration address computation as described in this document: https://hackmd.io/@wollac/H1tZoCK0w

All these packages are tested against the full test vectors provided in the corresponding specifications.

Examples

  • bech32 encode and decode addresses using the bech32 address scheme.
    Run the example with go run examples/bech32/main.go and use -help to see the available commands.
  • kdf shows the private and public key derivation using SLIP-10 and BIP-39 mnemonics + passphrase.
    It performs the legacy IOTA seed derivation (as implemented in the Ledger App) based on BIP-32 and the Ed25519 key derivation following SLIP-10.
    Run with go run examples/kdf/main.go and use -help to see the available command-line flags.
  • merkle prints the Merkle tree of several random transaction hashes on the console.
    Run with go run examples/merkle/main.go and use -help to see the available command-line flags.
  • mnemseed presents the extension of BIP-0039 to decode and encode 81-tryte legacy IOTA seeds using mnemonics.
    Run with go run examples/mnemseed/main.go and use -help to see the available command-line flags.
