May have to do with the size of the blocks you feed into the encoding (and decoding) parts

Base64 encoding : 3 bytes become 4 bytes (3 * 8 bits >> 4 * 6 bits)
The block - if not a multiple of 3 bytes is padded with = or == see http://en.wikipedia.org/wiki/Base64

To encode - feed blocks that are multiple of 3 bytes ( except the last block)


What is the code to Encode and Decode ?
