Some questions about rsyncrypto

[Michal 'h. S. <hra...@ce...>]

Hello

Unfortunately I cannot think of a more specific subject, I would just
like to clarify a few points which the documentation does not cover (or
does not state them clearly enough for me to understand).

First I wonder if rsynrypto does really solve the problem of syncing
effectively a file to which a single byte was inserted in the middle.

I myself would not hope any software would solve that for encrypted
files.  But I do not understand cryptography and a person who studied it
already assured me that it is likely possible to solve the problem.

Second I do not understand why a new key is generated for each file. Is
the encryption so severely wakened that one cannot afford encrypting
larger amount of data? What about files that are already gigabytes
or tens of gigabytes long?


Thanks
