Function

The program horcrux can split a file into a predefined number of horcruxes, or merge a predefinable sufficient number of constituent horcruxes in a directory back into the original file.

Split

To split up a file into horcruxes, call horcrux with the filename and optionally flags -n/--num with the number of desired horcruxes or -m/--min followed by the minimum number of horcruxes needed to merge back into the original file. Example:

horcrux -n 5 -m 3 secret.txt

The resulting horcruxes can be renamed, dispersed and later be used to put the original file back together if only the minimum number is met.

Merge

To merge horcruxes back into the original file, call horcrux in the directory containing the horcruxes, or pass that directory as an argument:

horcrux directory/with/horcruxes

Only files ending in .horcrux will be taken into account. There should not be any horcruxes in the directory that were produced at a different time or from a different file!

Query

To display information about a horcrux, call horcrux with the -q/--query flag followed by the filename of the horcrux in question, like:

horcrux -q file.horcrux
