    Method
    Description
    KeyPair
    deriveKeyPair(Seed seed)
    Derive a public/private keypair from a Base58Check encoded 16 byte seed.
    default Seed
    generateSeed()
    Generate a random 16-byte seed to be used to derive a private key.
    Seed
    generateSeed(Entropy entropy)
    Generate a 16 byte seed, which can be used to derive a private key, from a non-encoded value.

  • Method Details

    • generateSeed

      default Seed generateSeed()
      Generate a random 16-byte seed to be used to derive a private key.
      Returns:
      A String containing a randomly generated Base58Check encoded seed value.

    • generateSeed

      Seed generateSeed(Entropy entropy)
      Generate a 16 byte seed, which can be used to derive a private key, from a non-encoded value.
      Parameters:
      entropy - An UnsignedByteArray containing the bytes of entropy to encode into a seed.
      Returns:
      A String containing the Base58Check encoded seed value.

    • deriveKeyPair

      KeyPair deriveKeyPair(Seed seed)
      Derive a public/private keypair from a Base58Check encoded 16 byte seed.
      Parameters:
      seed - A Base58Check encoded String containing the seed.
      Returns:
      The KeyPair derived from the seed.
