Con Kolivas 373cfa25e4 limit must still be clamped to chunk_limit at most. 2011-03-23 08:44:52 +11:00
Con Kolivas 915edb78a2 Remove unused variables and functions. 2011-03-23 08:16:07 +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.

Con Kolivas 8fcedbc43e Fix big endian decompression from lzma. 2011-03-23 07:42:45 +11:00
Con Kolivas f7a1c14e28 Put warning about possibly wrong password at appropriate place in stream.c 
Use char to be consistent in open_stream_in.
Fail to failure() instead of fatal() should open_stream_in fail.

Con Kolivas 70e7866271 Include arpa/inet.h for those OSs that have endian details elsewhere. 2011-03-22 21:47:24 +11:00
ckolivas eebba614bc Don't adjust endianness in read_val. 2011-03-22 17:00:37 +11:00
ckolivas 36cc464d2b Yet more 32 bit clamping. 2011-03-22 14:44:56 +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.

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
Con Kolivas e7d33e82d0 Make read_1g able to read from the tmp outbuf if we decide to read from fd_out. 2011-03-19 14:46:06 +11:00

Con Kolivas 63fb1bafea Modify the file format further to make all block header information only encode the number of bytes determined in chunk_bytes instead of 8 full bytes all the time. 2011-03-18 23:18:36 +11:00
ckolivas b8d8ecfe33 Fix warnings. 
Patch ~ by Serge Belyshev.
 2011-03-18 10:37:09 +11:00

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 e78069c0d7 Consolidate magic writing to be able to seek to read and encrypt block header data later. 2011-03-17 16:59:27 +11:00
ckolivas 4bc23ee001 Centralise where all encryption/decryption is done, and whether to carry over the IV or not. 2011-03-17 14:10:58 +11:00
ckolivas 660243b8dc Pad out first block if less than CBC_LEN and encrypting or else encryption will fail. 2011-03-17 11:19:34 +11:00

This reverts commit 4314970b0d.

Oops, it can return invalid length.
 2011-03-16 10:00:20 +11:00
Con Kolivas 2d2a9bc1e9 We're freeing the wrong buffer by mistake should decompression fail. 2011-03-16 09:50:30 +11:00
Con Kolivas 4314970b0d aes_crypt_cbc always returns zero so ignore its return value. 2011-03-16 08:39:05 +11:00
Con Kolivas 519123966a total_read field is no longer used. 2011-03-16 08:32:16 +11:00
Con Kolivas 5da0633893 aes_crypt_cbc will allow you to work on the same buffer, so don't bother allocating a separate buffer. 
Allocate slightly more on the buffer that might be used for encryption rather than reallocing.
 2011-03-16 00:46:39 +11:00
