Exporting a Wrapped Key

To export a wrapped key:

1. Call the ExportWrappedKey method to export key bytes of symmetric key wrapped with RSA key bytes.

   Syntax

   
   public byte[] ExportWrappedKey(string keyName, byte[] wrapPublicKey, KeyWrapFormat wrapFormat)
   

2. Define KeyWrapFormat, it lists the algorithms used to wrap the symmetric key bytes.

   
   public enum KeyWrapFormat
   {
       RAW_PKCS1v15,
       RAW_PKCS1v21_RSAOAEP_SHA256,
       RAW_PKCS1v21_RSAOAEP_SHA384,
       RAW_PKCS1v21_RSAOAEP_SHA512,
   }
   

Sample code

NaeKeyManagement nkm = new NaeKeyManagement(session);
string keyname = "Sample_Aes_Key";
string public_keyname = "Sample_Rsa_Key";
byte[] exportedpublicBytes = nkm.ExportKey(public_keyname, NaeKeyManagement.KeyType.Public);
byte[] exportedWrappedBytes = nkm.ExportWrappedKey(keyname, exportedpublicBytes,
NaeKeyManagement.KeyWrapFormat.PKCS1v15);
