CRC for string

In a file compressed with any method of compression knew, the software must be reduce 127 of all the data of the file(remember that the file is opened in binary format, a array with a length equal to the length bytes of the file compressed) and must be, with any method, save in another file the file 127-reduced and a crc that let exactly know the positions of the array that has reduced 127. The lenght of the CRC must be maximum 3,5% of the original file lenght. The developer must send a .exe or a .jar demo for test the results, to the buyer.
