Include

using csharp_lib_crypto;

Seed generation

var crypto = new WavesCrypto();
string seed = crypto.RandomSeed();

Keys and address

publicKey

var crypto = new WavesCrypto();
string seed = "uncle push human bus echo drastic garden joke sand warfare sentence fossil title color combine";
var publicKey = crypto.PublicKey(seed);
int nonce = 0;
publicKey = crypto.PublicKey(seed, nonce);

privateKey

var crypto = new WavesCrypto();
string seed = "uncle push human bus echo drastic garden joke sand warfare sentence fossil title color combine";
var privateKey = crypto.PrivateKey(seed);
int nonce = 0;
privateKey = crypto.PrivateKey(seed, nonce);

keyPair

var crypto = new WavesCrypto();
string seed = "uncle push human bus echo drastic garden joke sand warfare sentence fossil title color combine";
var keyPair = new KeyPair(seed);

address

var crypto = new WavesCrypto();
string seed = "uncle push human bus echo drastic garden joke sand warfare sentence fossil title color combine";
var address = crypto.Address(seed, WavesChainId.MAIN_NET_CHAIN_ID); //or WavesChainId.TEST_NET_CHAIN_ID

Signatures

signBytes

var crypto = new WavesCrypto();
var seed = "uncle push human bus echo drastic garden joke sand warfare sentence fossil title color combine";
var bytes = new byte[] { 117, 110, 99, 108, 101};
            
var sign = crypto.SignBytes(bytes, seed);
            
var privateKey = "8bg5KM2n5kKQE6bVZssvwMEivc6ctyKahfGLkQfszZfY";
var sign2 = crypto.SignBytesWithPrivateKey(bytes, privateKey);

verifySignature

var crypto = new WavesCrypto();
var seed = "uncle push human bus echo drastic garden joke sand warfare sentence fossil title color combine";
var bytes = new byte[] { 117, 110, 99, 108, 101};
var sign = crypto.SignBytes(bytes, seed);
crypto.VerifySignature(publicKeyInit, bytes, sign);

Hashing

blake2b

var crypto = new WavesCrypto();
var bytes = new byte[] { 117, 110, 99, 108, 101};
crypto.Blake2b(bytes);

keccak

var crypto = new WavesCrypto();
var bytes = new byte[] { 117, 110, 99, 108, 101};
crypto.Keccak(bytes);

sha256

var crypto = new WavesCrypto();
var bytes = new byte[] { 117, 110, 99, 108, 101};
crypto.Sha256(bytes);

Random

randomBytes

var crypto = new WavesCrypto();
var size = 5;
var bytes = crypto.RandomBytes(size);

Base encoding\decoding

var crypto = new WavesCrypto();
var bytes = crypto.RandomBytes(32);

var base16String = crypto.Base16Encode(bytes);
var bytesFromBase16 = crypto.Base16Decode(base58String);

var base58String = crypto.Base58Encode(bytes);
var bytesFromBase58 = crypto.Base58Decode(base58String);

var base64String = crypto.Base64Encode(bytes);
var bytesFromBase64 = crypto.Base64Decode(base58String);

Messaging

- sharedKey

Utils

stringToBytes

var crypto = new WavesCrypto();
var bytes = new byte[] { 6, 7, 8, 4 };
var stringFromBytes = crypto.BytesToString(bytes);

bytesToString

var crypto = new WavesCrypto();
var bytes = "WAVES";
var bytesFromString = crypto.StringToBytes(stringFromBytes);
