This feature of rubyzip is experimental and may change in the future, but it seems to be working currently:. Rubyzip does provide a bunch of configuration options that can be either provided in the block:.
On Windows the default file permissions are set to as suggested by the Ruby File documentation. If bit 3 0x08 of the general-purpose flags field is set, then the CRC and file sizes are not known when the header is written.
The fields in the local header are filled with zero, and the CRC and size are appended in a byte structure optionally preceded by a 4-byte signature immediately after the compressed data.
If ::Zip::InputStream finds such entry in the zip archive it will raise an exception. AES encryption is not yet supported. It can be used with buffer streams, e. By default, rubyzip will not overwrite files if they already exist inside of the extracted path. By default, rubyzip will not overwrite files if they already exist inside of the extracted path.
