Sep05Exception

Base exception class for SEP-5 key derivation errors.

All SEP-5-specific exceptions extend this class to enable unified error handling while providing specific error types for different failure scenarios.

This exception hierarchy allows applications to handle key derivation errors at different levels:

• Catch Sep05Exception for general key derivation error handling

• Catch specific subclasses for precise error recovery

Common error scenarios:

• InvalidMnemonicException: General mnemonic validation failure

• InvalidEntropyException: Entropy size or format error

• InvalidChecksumException: Mnemonic checksum validation failed

• InvalidWordException: Word not found in word list

• InvalidPathException: Invalid BIP-32 derivation path

Example - General error handling:

try {
    val m = Mnemonic.from(phrase)
} catch (e: InvalidWordException) {
    println("Unknown word '${e.word}' in ${e.language.name} word list")
} catch (e: InvalidChecksumException) {
    println("Mnemonic checksum failed, check for typos")
} catch (e: Sep05Exception) {
    println("Key derivation error: ${e.message}")
}
