Private keys are often represented in Base58Check called a Bitcoin Secret (also known as Wallet Import Format or simply WIF), like Bitcoin Addresses.
Key privateKey = new Key(); // generate a random private keyBitcoinSecret mainNetPrivateKey = privateKey.GetBitcoinSecret(Network.Main); // generate our Bitcoin secret(also known as Wallet Import Format or simply WIF) from our private key for the mainnetBitcoinSecret testNetPrivateKey = privateKey.GetBitcoinSecret(Network.TestNet); // generate our Bitcoin secret(also known as Wallet Import Format or simply WIF) from our private key for the testnetConsole.WriteLine(mainNetPrivateKey); // L5B67zvrndS5c71EjkrTJZ99UaoVbMUAK58GKdQUfYCpAa6jypvnConsole.WriteLine(testNetPrivateKey); // cVY5auviDh8LmYUW8AfafseD6p6uFoZrP7GjS3rzAerpRKE9Wmuzbool WifIsBitcoinSecret = mainNetPrivateKey == privateKey.GetWif(Network.Main);Console.WriteLine(WifIsBitcoinSecret); // True
Note that it is easy to go from BitcoinSecret to private Key. On the other hand, it is impossible to go from a Bitcoin Address to Public Key because the Bitcoin Address contains a hash of the Public Key, not the Public Key itself. Process this information by examining the similarities between these two codeblocks:
Key privateKey = new Key(); // generate a random private keyBitcoinSecret bitcoinSecret = privateKey.GetWif(Network.Main); // L5B67zvrndS5c71EjkrTJZ99UaoVbMUAK58GKdQUfYCpAa6jypvnKey samePrivateKey = bitcoinSecret.PrivateKey;Console.WriteLine(samePrivateKey == privateKey); // True
PubKey publicKey = privateKey.PubKey;BitcoinPubKeyAddress bitcoinPublicKey = publicKey.GetAddress(ScriptPubKeyType.Legacy, Network.Main); // 1PUYsjwfNmX64wS368ZR5FMouTtUmvtmTY//PubKey samePublicKey = bitcoinPublicKey.ItIsNotPossible;
