I'm trying to write a class that can be used to generate public/private key pairs for bitcoin (and any of its 'clones'), I found some code elsewhere that uses BouncyCastle to generate keys, here's the part that is currently generating a private key:
protected void GeneratePrivateKeyHex()
{
ECKeyPairGenerator gen = new ECKeyPairGenerator();
var secureRandom = new SecureRandom();
var ps = Org.BouncyCastle.Asn1.Sec.SecNamedCurves.GetByName("secp256k1");
var ecParams = new ECDomainParameters(ps.Curve, ps.G, ps.N, ps.H);
var keyGenParam = new ECKeyGenerationParameters(ecParams, secureRandom);
gen.Init(keyGenParam);
AsymmetricCipherKeyPair kp = gen.GenerateKeyPair();
ECPrivateKeyParameters priv = (ECPrivateKeyParameters)kp.Private;
PrivateKeyBytes = priv.D.ToByteArrayUnsigned();
PrivateKeyHex = ByteArrayToString(PrivateKeyBytes);
}
I'd quite like to be able to create hierarchical deterministic keys using a seed and return a list of those (either by randomly generating a seed or by having a predefined one from a user) but I'm not entirely sure how to implement this!
Assuming I already have a seed, how would I go about generating the addresses for it using bouncycastle? Preferably while avoiding any bitcoin specific libraries as I'm trying to keep this class as generic as possible.
