Those who have large amounts of data to encrypt will anyway use a fast cipher and this means AES. Thus the 64 bit block length is in practice only a theoretical problem. A more practical problem is how to protect against arbitrary I/O or storage errors. Thus in the end you will store the data anyway in chunks. Shalom-Salam, Werner -- Die Gedanken sind frei.
