coinlib 3.1.0

coinlib: ^3.1.0 copied to clipboard

• Add .r and .s getters to SchnorrSignature with a new .fromRS constructor. The underlying bytes for a BIP340 signature can be obtained via .r.x and .s.data.
• Add .xhex convenience getter for ECPublicKey.

Fix SchnorrInputSignature not using SIGHASH_DEFAULT.

This release adds support for ANYPREVOUT and ANYPREVOUTANYSCRIPT. There have been numerous breaking changes.

• Refactored SigHashType to use OutputSigHashOption and InputSigHashOption. Adds ANYPREVOUT and ANYPREVOUTANYSCRIPT.
• Add TapLeafChecksig for single signature checksig tapscripts
• Add TaprootSingleScriptSigInput to sign tapscripts using TapLeafChecksig. Can sign using ANYPREVOUT and ANYPREVOUTANYSCRIPT.
• Replaced sign() with signLegacy(), signLegacyWitness(), signTaproot() and signTaprootSingleScriptSig().
• Added SignDetails with numerous subclasses for providing signing details for inputs. SignatureHasher subclasses and Input sign methods refactored accordingly.
• Taproot signatures are made using SIGHASH_DEFAULT by default.

Add ECCompressedPublicKey class that forces compressed public keys.

Final release for 2.1.0

• Add diffieHellman method to ECPrivateKey to allow generation of ECDH shared keys between two EC keys.
• Update secp256k1 to 0.5.0

Final release for 2.0.0

Fixes documentation links and improves usage of bytesEqual.

• Update secp256k1 to 0.4.1
• Update dart dependencies and FFI bindings

Add windows build support

• Add CoinUnit class to convert between amount strings and satoshis.
• Change NetworkParams to Network.

• P2WSHAddress.fromScript is now P2WSHAddress.fromRedeemScript and P2WSHAddress.fromScript is now P2WSHAddress.fromWitnessScript to remove ambiguity.
• P2WSH.fromRedeemScript is now P2WSH.fromWitnessScript in accordance with usual naming for P2WSH.
• Added MultisigProgram.sorted to allow multisig programs with ordered public keys.

Reduce output size of JavaScript by encoding WASM as base64

Fixed issues with build scripts

Move secp256k1 code to secp256k1 directory

Adds CoinSelection class with coin selection algorithms.

• Add Taproot support for key-path spends and script-path spends.
• Taproot keys and MAST trees are provided with the Taproot class.
• P2TRAddress support for Taproot addresses.
• P2TR provides Taproot program support for outputs.
• TaprootKeyInput and TaprootScriptInput provide Taproot input support.
• NUMSPublicKey allows key-path spending to be omitted.
• Signing logic has been moved to the inputs.
• InputSignature renamed to ECDSAInputSignature and some other name changes.

Final release for 1.0.0

• Make static variables immutable as final or const.

• Add forceLowR to ECDSASignature.sign that is true by default. This forces signatures to use a low r-value.
• Transaction signatures now use low r-values.

• Add witness transactions
• LegacyTransaction is replaced with a single Transaction class.

• Return HDPrivateKey from HDPrivateKey derivation
• Add example code
• hexToBytes and bytesToHex are now exposed

• Allow building secp256k1 for macOS using github download
• Require Dart 3
