InvalidCiphertextException

PrivateKey

A secret part of a key pair involved in ECDSA, the digital signature algorithm on which the Libplanet is based. It can be used to create signatures, which can be verified with the corresponding PublicKey, as well as to decrypt messages which were encrypted with the corresponding PublicKey.

Note that it uses secp256k1 as the parameters of the elliptic curve, which is the same to Bitcoin and Ethereum. It means private keys generated for Bitcoin/Ethereum can be used by Libplanet-backed games/apps too.

PublicKey

A public part of a key pair involved in ECDSA, the digital signature algorithm on which the Libplanet is based. It can be used to verify signatures created with the corresponding PrivateKey and to encrypt messages for someone possessing the corresponding PrivateKey. This can be distributed publicly, hence the name.

Note that it uses secp256k1 as the parameters of the elliptic curve, which is same to Bitcoin and Ethereum. It means public keys generated for Bitcoin/Ethereum can be used by Libplanet-backed games/apps too.

SymmetricKey

An AES-GCM symmetric key. Unlike PrivateKey and PublicKey that are involved in an asymmetric key cryptography, it uses the same SymmetricKey for both encrypting a plaintext and decrypting a ciphertext.
