Package org.bouncycastle.operator

Interface ContentVerifier

public interface ContentVerifier
General interface for an operator that is able to verify a signature based on data in a stream of output.

    Method
    Description
    org.bouncycastle.asn1.x509.AlgorithmIdentifier
    getAlgorithmIdentifier()
    Return the algorithm identifier describing the signature algorithm and parameters this verifier supports.
    OutputStream
    getOutputStream()
    Returns a stream that will accept data for the purpose of calculating a signature for later verification.
    boolean
    verify(byte[] expected)
    Return true if the expected value of the signature matches the data passed into the stream.

  • Method Details

    • getAlgorithmIdentifier

      org.bouncycastle.asn1.x509.AlgorithmIdentifier getAlgorithmIdentifier()
      Return the algorithm identifier describing the signature algorithm and parameters this verifier supports.
      Returns:
      algorithm oid and parameters.

    • getOutputStream

      OutputStream getOutputStream()
      Returns a stream that will accept data for the purpose of calculating a signature for later verification. Use org.bouncycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well.
      Returns:
      an OutputStream

    • verify

      boolean verify(byte[] expected)
      Return true if the expected value of the signature matches the data passed into the stream.
      Parameters:
      expected - expected value of the signature on the data.
      Returns:
      true if the signature verifies, false otherwise
