    • keyStoreType

      public final KeyStoreType keyStoreType()
      Deprecated.
      Description copied from interface: SignatureService
      The type of org.xrpl4j.crypto.keystore this signer can be used with.
      Specified by:
      keyStoreType in interface SignatureService
      Returns:
      A KeyStoreType.

    • sign

      public <T extends Transaction> SignedTransaction<T> sign(KeyMetadata keyMetadata, T transaction)
      Deprecated.
      Description copied from interface: TransactionSigner
      Obtain a signature for the supplied transaction using the private-key that corresponds to keyMetadata. If an implementation does not contain more than a single public/private key pair, then KeyMetadata.EMPTY should be passed into this method.
      Specified by:
      sign in interface TransactionSigner
      Type Parameters:
      T - The type of the transaction to be signed.
      Parameters:
      keyMetadata - A KeyMetadata that describes the public/private Keypair to use for signing operations.
      transaction - A Transaction to sign.
      Returns:
      A SignedTransaction containing binary data that can be submitted to the XRP Ledger in order to effect a transaction.

    • signWithBehavior

      public Signature signWithBehavior(KeyMetadata keyMetadata, Transaction transaction, SigningBehavior behavior)
      Deprecated.
      Description copied from interface: TransactionSigner
      Obtain a signature according to the behavior specified for the supplied transaction using the private-key that corresponds to keyMetadata. This method can be used to sign a multi-signed transaction by passing in SigningBehavior.MULTI.

      If an implementation does not contain more than a single public/private key pair, then KeyMetadata.EMPTY should be passed into this method.

      Specified by:
      signWithBehavior in interface TransactionSigner
      Parameters:
      keyMetadata - A KeyMetadata that describes the public/private Keypair to use for signing operations.
      transaction - A Transaction to sign.
      behavior - A SigningBehavior specifying the type of signature that should be produced.
      Returns:
      A Signature containing the transaction signature.

    • verify

      public <T extends Transaction> boolean verify(KeyMetadata keyMetadata, SignedTransaction<T> transactionWithSignature)
      Deprecated.
      Description copied from interface: TransactionVerifier
      TransactionVerifier the supplied digital-signature to ensure that it was constructed using the private-key corresponding to publicKey.
      Specified by:
      verify in interface TransactionVerifier
      Type Parameters:
      T - The actual type of Transaction.
      Parameters:
      keyMetadata - A KeyMetadata that describes the public/private Keypair to use for verification.
      transactionWithSignature - A SignedTransaction with a Signature over a supplied Transaction.
      Returns:
      true if the signature is valid and verified; false otherwise.

    • edDsaSign

      protected abstract Signature edDsaSign(KeyMetadata privateKeyMetadata, UnsignedByteArray signableTransactionBytes)
      Deprecated.
      Does the actual work of computing a signature using a ed25519 private-key, as locatable using privateKeyMetadata.
      Parameters:
      privateKeyMetadata - A KeyMetadata to describe the private-key to use for signing.
      signableTransactionBytes - A UnsignedByteArray to sign.
      Returns:
      A Signature with data that can be used to submit a transaction to the XRP Ledger.

    • ecDsaSign

      protected abstract Signature ecDsaSign(KeyMetadata privateKeyMetadata, UnsignedByteArray signableTransactionBytes)
      Deprecated.
      Does the actual work of computing a signature using a secp256k1 private-key, as locatable using privateKeyMetadata.
      Parameters:
      privateKeyMetadata - A KeyMetadata to describe the private-key to use for signing.
      signableTransactionBytes - A UnsignedByteArray to sign.
      Returns:
      A Signature with data that can be used to submit a transaction to the XRP Ledger.
