Class 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.
