Hi Steve,
First for the quick response.
a) For the encrypt file, it seems the behaviour is not reproduced when the file is encrypted:
#crypt_file <test.pl >testenc.pl
OK
# perl ./testenc.pl
$0 : ./testenc.pl
--
root 3189 2984 4 13:12 pts/1 00:00:00 xxxxxxxxxxx 1 2 3 4
--
$0 : xxxxxxxxxxx 1 2 3 4
But this is not valid for me because I would like to pack everything into a binary executable. But the good news it
seems the problem is not reproduce
b) I tested with PAR alone (no filter)
test01:~# ./test A B C
$0 : ./test
--
root 3257 2984 0 13:23 pts/1 00:00:00 xxxxxx A B C <-- See that!!
--
$0 : xxxxxxxxxxx 1 2 3 4
As you can see, it does not work either. If you apply a filter to the PAR archive (different from crypto) ...
test01:~# ./test A B C
$0 : ./test
--
root 3276 2984 30 13:24 pts/1 00:00:00 xxxxxx A B C <-- Same result with other filter??
--
$0 : xxxxxxxxxxx 1 2 3 4
Same behaviour. Something weird... only 6 first character are replaced and arguments seems to be missing as well.. (????)
Any ideas? Could it be related to PAR??

> Note that you're doing two things at once with the "pp -f Crypto..." command: you're encrypting the script and you're packaging it up into a PAR executable. Perhaps you could do some further tests to discover whether it is the encryption done by Filter-Crypto or the executable packaging done by PAR that is the cause of the problem.
