Function generateBip39MnemonicNonStandard

Parameters

• wordList: string[]

  a 2048-word array to use as the BIP39 word list

• entropyLength: Bip39ValidEntropyLength = Bip39.minEntropyBytes

  the entropy length to generate – 16, 20, 24, 28, or 32 bytes (defaults to 16).

• __namedParameters: {
      generateRandomBytes?: ((length, generate?) => Uint8Array);
  } = {}

  • Optional generateRandomBytes?: ((length, generate?) => Uint8Array)

    • • (length, generate?): Uint8Array

      • Generate a Uint8Array of the specified length containing a cryptographically-random series of bytes.

        For safety, this function first verifies that the provided generate function produces unique results across two evaluations; by default, this verifies that the crypto.getRandomValues function provided by the JavaScript environment appears to be producing random values.

        While this validation can't prevent a compromised environment from producing attacker-known entropy, it may help to prevent software defects in unusual environments (e.g. React Native) from impacting end-user security.

        An Error is thrown if this validation fails, otherwise, the Uint8Array produced by the first evaluation is returned.

        Parameters

        • length: number

          the length of the Uint8Array to generate

        • generate: ((length, cryptoInstance?) => Uint8Array) = generateRandomBytesUnchecked

          a function used to generate the random bytes, defaults to generateRandomBytesUnchecked.

          • • (length, cryptoInstance?): Uint8Array

            • Generate a Uint8Array of the specified length containing a cryptographically-random series of bytes. See generateRandomBytes for a safer alternative.

              Parameters

              • length: number

                the length of the Uint8Array to generate

              • cryptoInstance: {
                    getRandomValues: (<T>(array) => T);
                } = crypto

                an instance of the Crypto object with the getRandomValues function (defaults to the crypto global property).

                • getRandomValues: (<T>(array) => T)

                  • • <T>(array): T

                    • MDN Reference

                      Type Parameters

                      • T extends null | ArrayBufferView

                      Parameters

                      • array: T

                      Returns T

              Returns Uint8Array

        Returns Uint8Array
