So back to school again ....
Step 1
If you want to share something you have to create MD5 sums for those files. MD5 sum is unique number for each file and calculated using all bytes in the file. That means if you change only one byte in it, it will be completely different. It's not just simple summation of bytes, but very complicated mathematical calculation that can assure us that two different files can't have same MD5 sum.
Step 2
Someone downloads all files from person number 1 (md5 file included). That person will check his(her) files. Program will calculate MD5 sums on that person's hard disc and compare them with sums in MD5 file. If two sums are identical, file is 100% copy of the source. If sums are different files are not identical and difference can be only one byte or million bytes.
Thank you very much for your attention. :wink:
