Paid on delivery
I have working code of a packer and unpacker. The python packer, takes multiple files and adds them compressed into 1 file. The c unpacker, takes the above file and writes the files out. This fully works, with md5 checksum and zlib compression. I would like you to add to this. - encryption (AES or similar with libcrypto) - authentication with private and public cert. ( since the header contains the md5 of the separate files, only header authentication is enough).
