BoxDBox uses Huffman Coding Algorithm and SHA256 Hashing to box and unbox your file. In a high level, BoxDBox read bytes of your file and construct the huffman tree where the huffman tree is constructed in a greedy mechanism such that the most frequent byte should be positioned as a leaf node with the shortest path from the root. In this design, the Huffman Tree is binary. The compressed bits of a byte data is derived from the path of root to the leaf node, whereof the left traversal consider an append of '0' and right traversal consider an append of '1'.
To track of a original byte with its compressed binary representation,
we uses a HashMap<Byte,String> in which we called it
a Huffman Table. Finally, by referring to Huffman Table with the original
byte array we construct a Huffman Code String, a string with concatenations
of all compressed byte binary representation.
We serialize a packet that consists of Huffman Code String, Huffman Table, and a SHA256 hashed secret key to the .box file. To unbox a file, we went through a validation phase. In validation phase, we check the validity deserialization of packet and verify the secret key by a hashing match.
