BIP39

Convenience object for BIP-39 mnemonic operations.

This is a facade that delegates to a MnemonicService implementation. Uses BitcoinJ implementation which is BIP-39 compliant and battle-tested.

Reference: https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki

Usage:

// Generate 24-word mnemonic
val mnemonic = BIP39.generateMnemonic()

// Convert to seed (CRITICAL: wipe seed after use!)
val seed = BIP39.mnemonicToSeed(mnemonic)
try {
    // Use seed...
} finally {
    Arrays.fill(seed, 0.toByte())
}

// Validate mnemonic
val isValid = BIP39.validateMnemonic(mnemonic)

Thread Safety: All methods are thread-safe. The service implementation is immutable.

Testing: For testing with custom implementations, use constructor injection in your components rather than relying on this global object.
