Do you really think Boost has to cater for this kind of situations (some nut-case with a pkzip file. I would do a one time unzip with pkzip, and re-zip with lzma or something of that kind), while earlier today, the suggestion of having a signed size_type is readily rejected. I doubt there are many even bigger nut-cases that still keep generating pkzip-archies in 2020)? Meanwhile zip files are still the single most popular archive format on

Go to https://itch.io/ and you'll find thousands of indie games, the vast majority of them packaged as zip. Download a Java jar file and you'll be downloading a zip file with a different extension. Same with .docx. Granted, most of these zip files aren't encrypted. And if I really wanted to read from a zip file, I'd use a third-party library like libzip or libarchive to do the heavy lifting. It was just an example to demonstrate that there are use cases for specific encryption methods, even when those algorithms are known to be method. (Implementing TLS would be another example, although again one where higher-level libraries exist. Reading obscure encrypted file formats would a more compelling example, because there often isn't a readily available library around to do the heavy lifting, but the very nature of obscure file formats is that they are obscure, i.e. I can't think of any off of the top of my head.) -- Rainer Deyke (rainerd@eldwood.com)
