They are correct because SHA1 was designed to make it very hard to construct two files that hash to the same value Unless one is very cleverly contructing files to hash to the same value one will have to create about 2^80 files, before two of them are likely to hash to the same value - which is vastly more than one is likely to have. If one is very cleverly constructing files to hash to the same value, things get complicated - but the numbers are still far vaster than one is going to encounter in practice --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "leo-editor" group.
