Path to file\n2. File hash (real or deceiving one)\n\n#### Possible outputs\n- If an original file is upload along with its real hasg, the server will return the file (its hash will be shown) after going through PoW protocol.\n- If an original file is uploaded along a wrong/deceiving hash, the server will upload the file (if it exists, the file will be uploaded, if not, the server won't do anything).\n- If a manipulated file is uploaded along with a wrong hash, the server will upload the file (it will calculate the manipulated file hash).\n- If a manipulated file is uploaded along with its hash, the server will upload the file.\n\n#### License\n\nCopyright 2018 Francisco Javier Rodrigo Ginés\n\nThis program is free software: you can redistribute it and/or modify\nit under the terms of the GNU General Public License as published by\nthe Free Software Foundation, either version 3 of the License, or\n(at your option) any later version.\n\nThis program is distributed in the hope that it will be useful,\nbut WITHOUT ANY WARRANTY; without even the implied warranty of\nMERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
