GZIP Security Features


Extended functionality to ensure data integrity is not specified for GZIP according to its approach. Optionally the header information could be protected by the least significant word of the CRC-32 checksum created up to this point. The full 32 bit CRC code of the entire (uncompressed) data will be added following the compressed data.


Additional procedures to add redundancy improving error tolerance are not specified. Mechanisms like this would exceed the scope GZIP. In common pratice this would be part of higher protocol levels.


Encryption is also not defined for GZIP. The same considerations as made for data integrity are valid for encryption features.
