  • Method Details

    • sign

      byte[] sign(JwsAlgorithm algorithm, String data)
      Signs the given String data using the Java Cryptographic algorithm defined by the JwsAlgorithm. The signature is created using the given private key.
      Parameters:
      algorithm - The JwsAlgorithm defining the Java Cryptographic algorithm.
      data - The data to be signed.
      Returns:
      A byte array of the signature.

    • sign

      byte[] sign(JwsAlgorithm algorithm, byte[] data)
      Signs the given raw data bytes using the Java Cryptographic algorithm defined by the JwsAlgorithm.
      Parameters:
      algorithm - the JWS signature algorithm to use.
      data - the raw data to sign.
      Returns:
      the signature.

    • verify

      boolean verify(JwsAlgorithm algorithm, byte[] data, byte[] signature)
      Verifies that the given signature is valid for the given data.

      Uses the Java Cryptographic algorithm defined by the JwsAlgorithm and private key to create a new signature of the data to compare against the given signature to see if they are identical.

      Parameters:
      algorithm - The JwsAlgorithm defining the JavaCryptographic algorithm.
      data - The data that was signed.
      signature - The signature of the data.
      Returns:
      true if the signature is a valid signature of the data.
