## Interface ContentVerifier

-     public interface ContentVerifier

- - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `org.bouncycastle.asn1.x509.AlgorithmIdentifier` | `getAlgorithmIdentifier()` Return the algorithm identifier describing the signature algorithm and parameters this expander supports.
    `java.io.OutputStream` | `getOutputStream()` Returns a stream that will accept data for the purpose of calculating a signature for later verification.
    `boolean` | `verify(byte[] expected)`

- - ### Method Detail

    - #### getAlgorithmIdentifier

          org.bouncycastle.asn1.x509.AlgorithmIdentifier getAlgorithmIdentifier()

      Return the algorithm identifier describing the signature algorithm and parameters this expander supports.
      Returns:
        algorithm oid and parameters.

    - #### getOutputStream

          java.io.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)

      Parameters:
        `expected` - expected value of the signature on the data.
      Returns:
        true if the signature verifies, false otherwise
