shuffle3 - 3 stage byte shuffler
Deterministically and reversably shuffle a file's bytes around.
Shuffling
Shuffle a file in place
$ shuffle3 -s file
Unshuffling
Unshuffle a file in place
$ shuffle3 -u file
Other options
Run with --help
for more options.
Building
Run make
to build the normal binary. It will output to shuffle3-release
.
Release target
The release
(default) target uses the variables RELEASE_CFLAGS
and RELEASE_LDFLAGS
to specify opitimisations. These can be set by you if you wish.
Note
The default RELEASE_CFLAGS
contains the flag -march=native
. This may be underisable for you, in which case set the variable or modify the makefile to remove it.
Debug target
To build with debug information, run make debug
. Extra debug flags can be provided with the DEBUG_CFLAGS
and DEBUG_LDFLAGS
variables which have default values in the Makefile.
The build and unstripped binary will be shuffle3-debug
.
Notes
Before switching between release
and debug
targets, remember to run make clean
.
