  • Method Summary

    Modifier and Type
    Method
    Description
    default <T extends Transaction>
    boolean
    verify(Set<SignatureWithPublicKey> signatureWithPublicKeys, T unsignedTransaction)
    Verify that all signers have properly signed the unsignedTransaction.
    <T extends Transaction>
    boolean
    verify(Set<SignatureWithPublicKey> signatureWithPublicKeys, T unsignedTransaction, int minSigners)
    Verify that minSigners from the collection of public keys have supplied signatures for a given signed transaction.
    <T extends Transaction>
    boolean
    verify(SignatureWithPublicKey signatureWithPublicKey, T unsignedTransaction)
    Verify the supplied digital-signature to ensure that it was constructed using the private-key corresponding to signerPublicKey.

  • Method Details

    • verify

      <T extends Transaction> boolean verify(SignatureWithPublicKey signatureWithPublicKey, T unsignedTransaction)
      Verify the supplied digital-signature to ensure that it was constructed using the private-key corresponding to signerPublicKey.
      Type Parameters:
      T - The actual type of Transaction.
      Parameters:
      signatureWithPublicKey - A SignatureWithPublicKey used for verification.
      unsignedTransaction - The Transaction of type TransactionVerifier that was signed.
      Returns:
      true if the signature is valid and verified; false otherwise.

    • verify

      default <T extends Transaction> boolean verify(Set<SignatureWithPublicKey> signatureWithPublicKeys, T unsignedTransaction)
      Verify that all signers have properly signed the unsignedTransaction.
      Type Parameters:
      T - The actual type of Transaction.
      Parameters:
      signatureWithPublicKeys - A Set of SignatureWithPublicKey used for verification.
      unsignedTransaction - The Transaction of type TransactionVerifier that was signed.
      Returns:
      true if a minimum number of signatures are valid for the supplied transaction; false otherwise.

    • verify

      <T extends Transaction> boolean verify(Set<SignatureWithPublicKey> signatureWithPublicKeys, T unsignedTransaction, int minSigners)

      Type Parameters:
      T - The actual type of Transaction.
      Parameters:
      signatureWithPublicKeys - A Set of SignatureWithPublicKey used for verification.
      unsignedTransaction - The transaction of type TransactionVerifier that was signed.
