IOTA crypto demo

This repository contains Go example implementations related to the cryptography RFCs in iotaledger/protocol-rfcs.

Packages

It contains the following general packages:

encoding/b1t6 implements the binary-to-ternary encoding as described in the IOTA protocol RFC-0015.
bech32 implements Bech32 addresses based on the format described in RFC-0020 draft.
bip32path provides utilities for BIP-0032 chains.
bip39 implements the BIP-0039 specification and mnemonic word lists.
ed25519 implements Ed25519 signatures with particular validation rules around edge cases as described in RFC-0028 draft.
merkle implements the combination of multiple bundle hashes into one Merkle tree as described in the IOTA protocol RFC-0012.
pow implements the Curl-based proof of work for arbitrary binary data as mentioned in RFC-0017 draft.
slip10 implements the SLIP-0010 private key derivation.

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

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-0010 and BIP-0039 mnemonics + passphrase.
It performs the legacy IOTA seed derivation (as implemented in the Ledger App) based on BIP-0032 and the Ed25519 key derivation following SLIP-0010.
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.
