[edit] Merge with PAR File

I vote yes merge them. I'm willing to do it, they're both small. Have PAR/PAR2 files redirect tho so we don't get dupes again. -- RevRagnarok 02:03, 15 May 2006 (UTC)

Beat ya to the merge. ;) Cwolfsheep 20:09, 3 June 2006 (UTC)

Cool, I was just looking it over, kudos! -- RevRagnarok ^{Talk Contrib Reverts} 16:23, 4 June 2006 (UTC)

[edit] Big rewrite

Please comment. Spent quite some time on it. -- RevRagnarok ^{Talk Contrib Reverts} 04:52, 10 June 2006 (UTC)

[edit] Other uses

Please contribute... I do what I mentioned with CD-R and DVD-R because I have had CD-Rs fade in the sun and get bit errors. The DAR stuff is just an extra precaution. — RevRagnarok ^{Talk Contrib} 05:56, 10 June 2006 (UTC)

Here is my Makefile. It will skip the subdirectory "Processed." I've used it on Linux and Cygwin:

OUT=RevRagnarok.par2
REDUNDANCY=10

.SILENT: all $(OUT)

SUBDIRS = $(shell find . -iwholename './Processed' -prune -o -type d -printf "''%P'Y'" | perl -pe 's/^\x27\x27\x27Y\x27//g;s/ /\\ /g;s/\x27\x27/ /g;s/\x27*Y\s*\x27/\/$(OUT) /g')

.PHONY: subdirs $(SUBDIRS)

HERE = $(shell pwd | perl -pe 's/ /\\ /g')

subdirs: $(SUBDIRS)

$(SUBDIRS):
        @$(MAKE) $(MAKEFLAGS) -C "$(patsubst %/$(OUT),%,$@)" -f $(HERE)/Makefile par2_files

par2_files : $(OUT)

$(OUT) : 
        $(if $(wildcard *.mp3), par2 c -v -r$(REDUNDANCY) $@ *.mp3, )

[edit] Shouldn't be used for security

PAR does not use cryptographically secure checksums, and therefore cannot be used to assure edits have not occurred. Cryptographically secure checksumming algorithms such as SHA-1 should be used instead.
