    • fromBase64

      public static byte[] fromBase64(String data)
      Decode a base64 string into a byte array.
      Parameters:
      data - the encoded data.
      Returns:
      a byte array.

    • longFromBase64

      public static long longFromBase64(String value)
      Decode a base64 string into a long value.
    • toBase64

      public static String toBase64(byte[] data)
      Converts a byte array into a base 64 encoded string. Null is encoded as null, and an empty array is encoded as an empty string. Otherwise, the byte data is read 3 bytes at a time, with bytes off the end of the array padded with zeros. Each 24-bit chunk is encoded as 4 characters from the sequence [A-Za-z0-9$_]. If one of the source positions consists entirely of padding zeros, an '=' character is used instead.
      Parameters:
      data - a byte array, which may be null or empty
      Returns:
      a String
    • toBase64

      public static String toBase64(long value)
      Return a string containing a base-64 encoded version of the given long value. Leading groups of all zero bits are omitted.
