Change key generation method

[gidung2]

How do I change the key generation method from secure random to bip39 seed? I modified the json as in the example and ran it, but the cmd window closed.

{
  "command": "Find",
  "finder": {
    "keyProducerJavaRandom": [
      {
        "keyProducerJavaRandomInstance": "SECURE_RANDOM",
        "customSeed": 0,
        "keyProducerId": "exampleKeyProducerSecureRandomId",
        "privateKeyMaxNumBits": 256
      }

Here, i change the secure_random to bip39_seed
but not working

{
  "keyProducerJavaRandomInstance": "BIP39_SEED",
  "mnemonic": "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about"
}

I did it as an example, but it was forced to terminate the same way.

Hi,

Here are some relevant lines of code for further reference:

• https://github.com/bernardladenthin/BitcoinAddressFinder/blob/main/src/main/java/net/ladenthin/bitcoinaddressfinder/configuration/CKeyProducerJavaRandomInstance.java#L79
• https://github.com/bernardladenthin/BitcoinAddressFinder/blob/main/src/main/java/net/ladenthin/bitcoinaddressfinder/configuration/CKeyProducerJavaRandom.java#L23
• https://github.com/bernardladenthin/BitcoinAddressFinder/blob/main/src/main/java/net/ladenthin/bitcoinaddressfinder/KeyProducerJavaRandom.java#L73
• https://github.com/bernardladenthin/BitcoinAddressFinder/blob/main/src/main/java/net/ladenthin/bitcoinaddressfinder/BIP39KeyProducer.java#L52

Please change the configuration from:

"keyProducerJavaRandom": [
  {
	"keyProducerJavaRandomInstance": "SECURE_RANDOM",
	"customSeed": 0,
	"keyProducerId": "exampleKeyProducerSecureRandomId",
	"privateKeyMaxNumBits": 160
  }
],

to:

"keyProducerJavaRandom": [
  {
	"keyProducerJavaRandomInstance": "BIP39_SEED",
	"mnemonic": "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about",
        "passphrase": "",
	"keyProducerId": "exampleKeyProducerSecureRandomId",
	"privateKeyMaxNumBits": 160
  }
],

You might also want to set:

"logSecretBase": true,

to see which base addresses are used for the OpenCL chunks generated from the BIP39 seed. I assume you have not set the passphrase to an empty string (or not set it at all).

I've improved the README.md, thanks a lot: 078da31
