PrivateKey class abstract interface

Interface for asymmetric private keys (part of a key pair).

Private keys are used for:

  • Decrypting data encrypted with the corresponding public key
  • Generating digital signatures verifiable by the public key

Key data format (serialized as Map/JSON):

{
  "algorithm" : "RSA",  // "ECC", ...
  "data"      : "{BASE64_ENCODE}",
  // Additional algorithm-specific parameters
  // (e.g., key size, curve name)
}

Implements SignKey for digital signature generation.
