Methods

ecRecover(int recId, Uint8List messageHash, SignatureData signature, [bool isCompressed = false, bool isEthereum = false]) → Uint8List

Given an arbitrary message hash and an Ethereum message signature encoded in bytes, returns the public key that was used to sign it. https://github.com/web3j/web3j/blob/c0b7b9c2769a466215d416696021aa75127c2ff1/crypto/src/main/java/org/web3j/crypto/Sign.java#L241

generateKeypair([SecureRandom? random]) → AsymmetricKeyPair<PublicKey, PrivateKey>

generatePrivateKey([SecureRandom? random]) → BigInt

generatePrivateKeyBytes([SecureRandom? random]) → Uint8List

getPublicKey(BigInt privateKey, [bool isCompressed = true]) → Uint8List

If isCompressed is true, return public key length is 33 (flag + x), otherwise, public key length is 64 (x + y)

getPublicKeyFromPrivateKeyBytes(Uint8List privateKey, [bool isCompressed = true]) → Uint8List

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

recoverFromSignature(int recId, ECSignature sig, Uint8List msg, [bool encoded = false]) → Uint8List?

recoveryId(ECSignature signature, Uint8List messageHash, Uint8List publicKeyBytes) → int

sign(Uint8List messageHash, Uint8List privateKey, [bool isEthereum = false]) → SignatureData

toString() → String

A string representation of this object.

inherited

verifySignature(Uint8List messageHash, SignatureData signature, Uint8List publicKey) → bool

Operators

operator ==(Object other) → bool

The equality operator.
