Con Kolivas	77d44ce108	Disable output when it's not known. More endian fixes.	2011-03-20 22:22:54 +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
ckolivas	e856d481bf	Discard hash_iv entirely, using passphrase hash and centralise key generation. ... Patch by Serge Belyshev.	2011-03-18 10:22:58 +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
Con Kolivas	5fd7c82e1f	Implement ciphertext stealing to not have to pad compressed blocks courtesy of Serge Belyshev who saved me hours of debugging thanks!	2011-03-16 21:24:05 +11:00

Con Kolivas	65f901a83c	Get the seconds, salt and encryption loop data before compressing. ... Store seconds in only 5 bytes which is enough for 400 years, leaving more room for random data.	2011-03-15 14:41:47 +11:00
Con Kolivas	6a903eff8d	Convert the usecs field to a dedicated salt one which has 6 random bytes and 2 encoded loops bytes.	2011-03-15 13:14:27 +11:00
ckolivas	65a681a254	Relative offset is not required in tmp inbuf, it can be safely zeroed.	2011-03-15 11:21:26 +11:00
