bip_utils

Add support for Cardano:

• Cardano Byron legacy (old Daedalus addresses, i.e. Ddz...)
• Cardano Byron-Icarus (Yoroi addresses in the Ae2... format)
• Cardano Shelley (Yoroi addresses in the addr1... format)

Add support for Ergo (Bip44Coins.ERGO, Bip44Coins.ERGO_TESTNET)

Add ChainCode method to Bip32 and Bip44 key classes to quickly get it

Add PublicKey method to Bip44PrivateKey

Bip32Base class:

• Add Curve method
• Remove IsPrivateUnhardenedDerivationSupported method (same meaning of IsPublicDerivationSupported)

Bip32KeyIndex class:

• Bip32Utils methods move to Bip32KeyIndex
• Add Harden/Unharden methods to Bip32KeyIndex

DataBytes class:

• Add possibility to get length (Length, Size, __len__)
• Add possibility to check for equality (__eq__)
• Add possibility to iterate over bytes (__iter__)

Add Curve method to Bip32PublicKey/Bip32PrivateKey classes

Add possibility to create a Bip32PublicKey class from an IPoint instance

Add CurveType method to IPoint classes

BIP32 classes were renamed in a consistent way:

• Bip32Ed25519Slip -> Bip32Slip10Ed25519
• Bip32Ed25519Blake2bSlip -> Bip32Slip10Ed25519Blake2b
• Bip32Nist256p1 -> Bip32Slip10Nist256p1
• Bip32Secp256k1 -> Bip32Slip10Secp256k1
• Bip32Ed25519Kholaw -> Bip32KholawEd25519

Old classes kept for compatibility

Update key net version to get xprv prefix for BIP32 Kholaw private extended keys

• Mnemonic-specific checksum exceptions (i.e. Bip39ChecksumError and MoneroChecksumError) were replaced by the common MnemonicChecksumError

• Add implementation of SLIP-0010
• Add support for nist256p1, ed25519, ed25519-blake2b and sr25519 curves
• Add support for new coins based on the new curves (see below)
• Add support for Substrate (Polkadot ecosystem) keys derivation and addresses generation
• Add support for Monero mnemonic generation and validation
• Add support for Monero keys derivation and addresses/subaddresses generation
• Usage of coincurve library for secp256k1 curve (still possible to use ecdsa, anyway)
• Better usage of private and public keys:
  • Improved and more complete class hierarchy and design
  • Easier construction (from bytes, from point, from object)
  • Possibility to pass as argument the key object in addition to key raw bytes (e.g. to methods of Bip and address classes)
  • Keys validation
  • Possibility to use both compressed/uncompressed public keys without the need of converting
• General code refactoring and re-design to keep everything neat and tidy

• BIP44 coins:
  • Algorand
  • Elrond
  • Filecoin
  • Kusama (based on BIP44 and ed25519 SLIP-0010, like TrustWallet, it won't generate the same addresses of Polkadot-JS)
  • Monero (based on BIP44 and secp256k1 or ed25519 SLIP-0010, it won't generate the same addresses of the official wallets but it supports subaddresses generation)
  • Nano
  • NEO
  • Ontology
  • Polkadot (based on BIP44 and ed25519 SLIP-0010, like TrustWallet, it won't generate the same addresses of Polkadot-JS)
  • Solana
  • Stellar
  • Tezos
  • Theta Network
  • Zilliqa
• Substrate coins (based on the official wallet, e.g. Polkadot-JS):
  • Acala
  • Bifrost
  • Chainx
  • Edgeware
  • Karura
  • Kusama
  • Moonbeam
  • Moonriver
  • Phala Network
  • Plasm Network
  • Sora
  • Stafi
  • Polkadot
  • Generic Substrate coin
• Monero (based on the official wallet)

• Bip32 class does not exist anymore. It has been replaced by different classes depending on the underlying elliptic curve: Bip32Ed25519Slip, Bip32Ed25519Blake2bSlip, Bip32Nist256p1, Bip32Secp256k1
• Bip49 and Bip84 now have their own coin types: Bip49Coins and Bip84Coins
• Bip39MnemonicValidator.GetEntropy method has been replaced by Bip39MnemonicDecoder.Decode method
• The mnemonic in Bip39MnemonicValidator class is passed as argument to the methods instead of the constructor (e.g. Bip39MnemonicValidator(mnemonic).IsValid() -> Bip39MnemonicValidator().IsValid(mnemonic))
• P2PKH, P2SH and P2WPKH address classes now have an "Addr" suffix (i.e. P2PKHAddr, P2SHAddr and P2WPKHAddr, same for BCH versions)
• In address classes, the ToAddress method now is called EncodeKey (e.g. EthAddr.ToAddress -> EthAddr.EncodeKey) and the additional parameters shall be explicitly named
• AtomBech32Decoder/AtomBech32Encoder is now simply called Bech32Decoder/Bech32Encoder
• P2PKHAddr/P2SHAddr/P2WPKHAddr classes do not have anymore Bitcoin net versions as default parameter
