First I was thinking to start a LZMA compression but that dictionay based thing is quite heavy and not for the text commpression.
Now I have decided to implement this cypher text with help of Hffman encoding algo.
Please share some codes in .Net and Java through which I could implement compression.
Remember that I will have to do encryption also after this compression.
In short I have to compress/decompress and encrypt/decrypt the text files.
