A newer '.sss' version (found packed inside a '.gar' container format) does appear to have been obfuscated: adding/subtracting a certain amount to each byte from the output of a xorshift PNR, seeded from the file-headers supplied immediately before the compressed stream: https://github.com/sladen/pat/blob/master/gar.py#L130 https://en.wikipedia.org/wiki/Xorshift Obfuscation (as found here) is not encryption. But neither is ROT13 encryption either: https://en.wikipedia.org/wiki/ROT13 -Paul -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
