    • anonymize

      public void anonymize()
      Anonymizes the HMAC pair by removing the public secret key.

    • toByteArray

      public byte[] toByteArray() throws IOException
      Serializes this Crypto_HmacPair into a byte array using standard Java object serialization, delegating to Crypto_SerializationUtils.serialize(Object).
      Returns:
      the serialized bytes
      Throws:
      IOException - if an I/O error occurs during serialization

    • fromByteArray

      public static Crypto_HmacPair fromByteArray(byte[] data) throws IOException, ClassNotFoundException
      Deserializes a Crypto_HmacPair from a byte array, delegating to Crypto_SerializationUtils.deserialize(byte[]).
      Parameters:
      data - the bytes produced by toByteArray()
      Returns:
      the reconstructed Crypto_HmacPair
      Throws:
      IOException - if an I/O error occurs during deserialization
      ClassNotFoundException - if the class of the serialized object cannot be found

    • toString

      public String toString()
      Returns a string representation of the Crypto_HmacPair.
      Overrides:
      toString in class Object
