Horcrux

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
