Sign and SignVerify Data using an RSA Key

To Sign and SignVerify data using an RSA key:

1. Create a NAE Session. Pass the NAE username, password, property file path as arguments.

   
   NaeSession session = new NaeSession(user, passwd, propFilePath);
   

2. Create NaeRsaKey object. Pass NaeSession object and keyname as argument.

   
   NaeRsaKey rsaKey = new NaeRsaKey(session,keyName);
   

3. Set the Hash algorithm.

   
   HashAlgorithmName algorithm = HashAlgorithmName.SHA256;
   

4. Call the SignData API and pass input bytes, hashing algorithm name, and RSASignaturePadding as arguments to get the signed bytes.

   
   byte[] outBytes = rsaKey.SignData(inputBytes, algorithm, padding);
   

5. Call the VerifyData API. Pass the signed bytes, input bytes,algorithm name, and RSASignaturePadding as arguments for the verification of signed data.

   
   bool result = rsaKey.VerifyData(inputBytes, outBytes, algorithm, padding);
