WHAT ========================================================================
Horcrux takes an input file/archive, encrypts it, hex encodes it and then
breaks it apart into n equal pieces, or x pieces of <= n bytes. Horcrux
can also take a directory of horcrux pieces and concatenate, decode then
decrypt them to recreate the original file. Horcrux requires GnuPG.
USAGE =======================================================================
$ ./horcrux.sh split -i file -n name -p pass -s n OR -b n[k|m]
where -i = input file/archive
-n = a unique name identifying this horcrux
-p = the password used to encrypt this horcrux
-s = split the horcrux into n pieces of equal bytes, OR
-b = split the horcrux into x pieces of max n[k|m] bytes
k represents kilobytes, m megabytes; example: -b 1k, -b 20m
if no unit is provided bytes are assumed; example: -b 500
Creates a new horcrux inside a folder (named by -n). Note that only the
-s or -b flag need be specified at a time, never both.
$ ./horcrux.sh join -i folder/of/pieces -p pass
where -i = a folder containing horcrux pieces
-p = the password used to decrypt this horcrux
Concatenates, decodes and decrypts a horcrux to recreate the original file.
EXAMPLES ====================================================================
Split a file, archive.tar, into 5 equal pieces:
$ ./horcrux.sh split -i archive.tar -n arch.1.10.15 -p secret -s 5
Split a file, disk.dmg, into 60mb pieces:
$ ./horcrux.sh split -i disk.dmg -n disk.1.10.15 -p secret -b 60m
Restore an original file from a directory of horcrux pieces:
$ ./horcrux.sh join -i ~/disk.1.10.15 -p secret
