Set the right order for the algorithm of base64 encoding.

Put the items in the correct order
add empty 6-bit groups if the last sequence encodes less than 3 bytes (24 bits)
add zeros if the last part of the binary sequence contains less than 6 bit
split the binary data into 6-bit groups
encode each of the groups according to the values in the index table
