Con Kolivas	e561a9a080	mremap is not a macro, check explicitly for freebsd and apple and define it only then.	2011-03-23 08:34:09 +11:00
Con Kolivas	b27e1df879	Revert "Modify the file format to not include rzip chunk size except for STDOUT chunked files thus decreasing the file format size further." ... This reverts commit 131d4c92c2. Breaks STDIN/OUT so revert this change and cope with the slightly extra file size on non-chunked files.	2011-03-23 07:59:04 +11:00
Con Kolivas	8077412ee5	Allow files with non-standard extensions to be tested or decompressed if they actually exist. ... Don't allow a suffix if an actual output filename has been specified. Convert ints to chars when they can be.	2011-03-23 01:51:40 +11:00
ckolivas	df1ec6dd08	Remove unused.	2011-03-22 13:06:44 +11:00
ckolivas	f56e48c4f2	Modify maxram to mean the most we'll allocate in one chunk and add usable_ram for the most we'll allocate to one task. ... Limit all maxram on 32bits to 1GB since most don't like mallocing more than this. Update testing to allow larger total amount based on usable ram while sticking to maxram limit per alloc.	2011-03-22 12:10:21 +11:00

Con Kolivas	0dad7dcc5a	Modify the encrypted version to not write down the rzip chunk size, then keep track of where each block header is written, go back and write 8 bytes of salt before it and encrypt the headers in place.	2011-03-20 15:45:44 +11:00
ckolivas	5005c2dff5	Get rid of extra data in new header and stick to old header size, compacting extra info into existing space.	2011-03-18 17:32:47 +11:00

Con Kolivas	a3e80871c2	Add 8 bytes of random data to the start of every encrypted compressed block and use it along with 8 bytes from the stored salt to make a unique key and IV for encryption.	2011-03-18 00:06:11 +11:00
ckolivas	d63a9a02ff	Use a separate IV for when it is sequentially updated in preparation for encrypting the headers as well.	2011-03-17 16:00:57 +11:00
