Re: best way to encrypt long file names?

Are you trying to encrypt or hash the filenames? Crypt is a one-way hash function (despite the name).

You could use something like Crypt::CBC and pump all your filenames through it. This is particularly desirable if you'd like to be able to recover the filenames again later.

use strict;
use warnings;

my $cbc = Crypt::CBC->new( -header=>"randomiv", -key => 'my secret key
+', -cipher => 'Blowfish' );
my $enc = $cbc->encrypt_hex("filename"); # recoverable hex phrase

Thank you so much for telling me about Crypt::CBC. It looks like this module would work great for encrypting strings, files and other data. However, the resulting encrypted strings are something like "Salted__8´•u,ÞÏZr¨Xfß6™ŒÄ9 þB#©ñüÃ". This would be fine if I was working with data, but this is not good for filenames. Thanks again for your help. I'm sure Crypt::CBC will come in handy in the near future.	[reply]

Why is it "not good?" Looks like you're not using encrypt_hex.	[reply]

Hence the reason my example uses encrypt_hex() ... There are many other ways to move from the binary bits to something suitable to your filesystem, but encrypt_hex is built in and easy... -Paul	[reply]
