    • getString

      public static String getString(int p_iLen)
      Create a cryptographically secure hex-encoded nonce value of the given length in bytes.

      Note that the length of the returned hex-encoded string is twice of the length in bytes.

      Parameter:
      p_iLen - The length of the nonce value in bytes.
      Gibt zurück:
      The hex-encoded nonce value.

    • getBinary

      public static byte[] getBinary(int p_iLen)
      Create a cryptographically secure hex-encoded nonce value of the given length in bytes.
      Parameter:
      p_iLen - The length of the nonce value in bytes.
      Gibt zurück:
      The nonce value.

    • getString58

      public static String getString58(int p_iLen)
      Create a cryptographically secure nonce value of the given length consisting of characters from the Base58 alphabet.

      The entropy of the values created by this method is p_iLen * log(58) / log(2).

      Parameter:
      p_iLen - The length of the nonce value in bytes.
      Gibt zurück:
      The hex-encoded nonce value.
