TonEntropyGeneratorUtils class

The TonEntropyGeneratorUtils class provides utility methods for handling entropy generation and validation related to the TON (The Open Network) blockchain. It includes methods to determine if a given entropy corresponds to a basic seed, a password-protected seed, and if a password is required based on a mnemonic phrase.

Constructors

Static Methods

generateEnteropy(Mnemonic mnemonic, {String password = ""}) → List<int>

Generates entropy from a given mnemonic and optional passphrase using HMAC-SHA512.

isBasicSeed(List<int> entropy) → bool

Determines if the provided entropy is a basic seed by using PBKDF2 with a predefined salt and iteration count. Returns true if the derived key's first byte is 0.

isPasswordNeed(Mnemonic mnemonic) → bool

Checks if a password is needed for the given mnemonic by generating its entropy and evaluating it with isPasswordSeed and isBasicSeed methods.

isPasswordSeed(List<int> entropy) → bool

Determines if the provided entropy is a password-protected seed by using PBKDF2 with a predefined salt and a single iteration. Returns true if the derived key's first byte is 1.

Constants
